" Prompt and transparent communication "

We were lucky to come across Deb through our house-hunting process. After a year of hunting, with no luck, coming across many unethical and dishonest real estate agents - Deb was a breath of fresh air. She was transparent in her communication and kept us informed throughout the process. I would not hesitate to recommend her!


" Excellent, well above expectations "

We found Deb Newton to be most helpful in assisting us to sell our home. It was the first time we were involved in selling a home, having lived in the same home for 59 years so, we really required the extra help and advice we received from Deb. Her market knowledge helped when we were deciding on a price and a selling date considering it was close to the holiday period. Deb achieved a great result, well beyond our expectations.

Roy & Carol

We are so pleased we chose Deb from Castlehaven to process the sale of our property. We are so impressed that the property only took about 2 weeks to be sold in the market! From doing all marketing and advertising to finding potential buyers and helping us negotiate a contract, Deb has provided her expertise and professional service during the process. She kept on updating us and answered all our questions with very detailed explanations, making sure we fully understood the purpose and necessity so that the process went smoothly and successfully. Thank you so much Deb, for your efforts and great job! We are so appreciative and highly recommend Deb to anyone looking for an experienced, top-notch, professional property agent.

I had a great experience with wonderful Deb who is highly recommended. She sold the house to me with satisfactory services. She is a reliable, honest, attentive and polite person with professional knowledge and experiences.


" Outstanding in every aspect "

Deb is nothing but professional to deal with. No matter what we asked or needed nothing was a problem for her at all. Deb's happy, easy going & caring attitude shines through no matter what she does. We were constantly kept up to date on the whole process & knowing that this could have been a very stressful experience became a very easy process. Thanks so much Deb you are amazing


" Incredibly helpful "

Deb is helpful and professional. Deb was incredibly helpful throughout the entire process. She provided thorough information regarding the price guide, allowing us to make informed decisions. Despite our late afternoon request for a house inspection, she readily arranged it and patiently waited for us, even when we were significantly delayed due to heavy traffic. Throughout the sales process, Deb consistently offered valuable support and communication, which played a crucial role in successfully closing the deal. We would not hesitate to recommend Deb to our friends based on her excellent service.

Iris Wu

" Helpful, good suggestions and follow through "

We chose Castlehaven and Vicky and Deb because they were enthusiastic and had good suggestions. They make the process as seamless as possible and they had ‘skin in the game’ for a result by covering the marketing/ advertising/ printing/ signboards and photography costs within the agreed percent of the sale price.

Mark Baker

" Great market knowledge "

Deb is a professional with great local market knowledge and brilliant communication. Deb was brilliant to deal with when selling our house. She works so hard to get the results for us.

Love your work, Deb! I found you a delight to work with. You were flexible, always positive and happy to go out of your way to fit in with our schedule to see the place. Negotiations are always tricky but you made the process easy. It has been a real pleasure doing business with you!

Justine Toh

" The best "

The BEST!! for knowledge; enthusiasm; thoughtfulness; always being contactable at ANY time; keeping me up to date with every aspect of the sale and never a negative, always a positive. An agent who is willing to help out at any time and go above and beyond - even providing coffee when I really needed it. For professionalism, knowledge, care, and a happy and positive attitude contact Deb. So glad I took up the recommendation to use her from another happy customer of hers!

Ruth Ricketts

" Honest and balanced "

I had inspected some properties before this and talked to many agents, and unlike some, Deb had a balanced and reasonable opinion of the property and its value. She also didn't push me to a rushed and uninformed decision and provided the information I needed. I'd recommend them if you want a fair buying experience.

Nafiseh Faramarzi

" Deb was outstanding "

Deb was recommended to sell our house and I’m so glad I went with that recommendation.

" Deb is brilliant "

One of the best people to deal with. She is a true professional and her communication skills are second to none! Love to deal with her.


" Deb was great! "

We recently entrusted Deb to sell our family home of 45 years. It was an emotional time for us all and Deb was understanding every step of the way. Deb and her team were very professional and negotiated to get a price we were very happy with. I'd highly recommend Deb to any prospective seller.


" Very professional & highly experienced "

I would highly recommend Deb Newton to sell your property. This is my second time dealing with her, and she has been able to achieve top price and sell both my properties very quickly.

Just sold my house and it wouldn’t have been possible without Deb. Deb was honest, respectful and understood and accommodated my needs from the get-go. The transaction flowed so smoothly and I’m very happy with the outcome.

Sallyanne Hage

" Smooth and stress-free experience with Deb "

I can't speak highly enough of Deb's professionalism and attention to detail. She has such a lovely, honest and transparent manner with excellent communication between all parties, and was always available when I had questions. Despite the slowing property market in late 2022, Deb sold my property in just one week at an impressive price, well above my expectations. This is my second time working with Deb, and she outdoes herself each time. I couldn't recommend her enough.


" So happy with Deb Newton "

I couldn't be happier with Deb Newton selling my house in 5 days. Deb was so knowledgeable of the local market and delivered on what she promised. Such a professional lady and always taking into consideration my concerns. I would recommend Deb to anyone considering selling.

Janine Caleo

" Deb was exceptional "

Deb was exceptional from the moment we placed our Baulkham Hills home for sale with her. She was very committed to the sale and kept us informed on every step of the way. Having owned our house for over 40 years ( this is the first home we have ever sold) we were a bit overwhelmed, but Deb took all the worry off our hands. After discussing the market downturn and the current interest rate hike, as well as the property sales in the surrounding area, we came up with a wIsh sale price which Deb chased relentlessly and did not except an inferior offer. After numerous text’s and phone calls we are pleased to say we got our wish plus a very handsome increase. We would highly recommend Deb to anyone who is considering engaging an agent in the Hills area.

Geoff & Cheryl Elliott

" Deb Delivered "

My wife & I felt comfortable with Deb from our initial meeting & were confident she had the experience & character to sell our property. All promises were met in a timely manner throughout the process with regular verbal & written reports on inspections, offers & questions raised by potential buyers. The negotiation phase really highlighted Deb’s competence & she was able to keep us calm & focused at all times. Her enthusiasm, dedication & skill combined to produce a very positive result, with the house selling in just 12 days. Deb has continued to assist us with relocating & has become a genuine friend. I venture to say the purchasers of our property would make similar comments about Deb’s professionalism, integrity & engaging personality.

Dick & Narelle

" Great Communication "

I would gladly recommend Deb to anyone who is considering selling their property. Castlehaven assisted with getting the property ‘sale ready’ and once on the market, found a buyer within only ten days in a falling market. Deb's communication was always very strong.


" Deb - Amazing AGAIN!! "

Deb, you've done it again! In trying times with interest rate rises and property market lulls, you still managed to get us the sale we were looking for. So glad we persisted. As always your communication was outstanding and we appreciated your honesty throughout the whole process. Thanks again!

Adrian Sutton

" Deb made the whole experience of selling our home easy and stress free! "

Deb is a true professional and her experience in the industry showed through in every step of the process of selling our home. She constantly kept in touch, letting us know about all enquiries and feedback from potential buyers. Deb has a lovely manner in dealing with both buyers and sellers, and is tenacious without being pushy. Deb gave us excellent advice and achieved a great sale for us, we couldn’t have been happier with the way she handled the sale of our home.

Manfred and Janette Oechsle

" Absolutely͏ amazing experience! "

Deb is your consummate professional. The sale was a painless experience for us and we greatly appreciate Deb's help and guidance as we have not sold property recently. I would have no hesitation in recommending Deb and Castlehaven to any of my family and friends if purchasing or selling a property!

Kathryn O'Donnell

" Stress͏ free sale! "

We engaged Deb on the recommendation of a friend, to sell my mum's home. We both felt immediately at ease and comfortable with Deb’s understanding of the market and her willingness to go out of her way to make things happen.

Melissa Matheson

" The best real estate company we have ever dealt with! "

Very professional, experienced and helpful agents. I can’t speak highly enough of Leanne, Montana, Deb and Patrick. Their professionalism, knowledge, honesty, integrity and hard work ethics are very much appreciated and respected. They have been incredibly helpful and understanding about our circumstances for the past 2 years. Highly recommend!

Hani Salehi

" Seriously brilliant! "

I've known Deb Newton and Castlehaven for many years and never actually used their services. To my loss, until now. They have been nothing but incredible. Deb is a pleasure to work with and is so refreshingly honest and caring of both the seller and buyer. I am so pleased to have had her sell my land and am currently listing another property with them. Don't bother looking around for another agent. You cannot beat Castlehaven and Deb's service and professionalism!

Leanne Cox

" Deb's Your Best Bet "

Deb’s the only agent which worked with zero fees upfront, which meant while every other agent wanted us to take the full risk upfront and pay the commission too, Deb and her team stood out by putting their money where their mouth (or ‘our house’) is. We got the price we wanted, and whether we put it down to our timing or Deb, it doesn’t matter - she delivered. Having talked to multiple agents, she was also the most open minded.


" Happy customer "

I would gladly recommend Deb Newton! She was very professional throughout our selling process and I have know her for many years now from previous sales.


" Perfectly organised! "

She did a great job from start to finish when selling my property. Deb is well organised, knows the market well, and has very good communication skills for every part of the process. I was so happy to work with her. A Strongly recommendable agent!!

Leanne Kim

" Professional "

A professional, organised and peace of mind experience with great communication all the way! Would definitely recommend Deb to be your sales agent.


" Above expectation "

Deb is an excellent communicator and was meticulous in updating us by phone, email and text. Her marketing skills yielded 180 inquiries and resulted in the sale of the property in 12 days. Deb arranged details of contracts and solicitor involvement seamlessly and without fuss. Additionally, Deb is personable and inspires confidence.

Geoffrey and Susan Brooke-Cowden

" Amazing service "

We were thoroughly impressed with the service provided by Deb and her team. Nothing was too much trouble, from accessing our rental property managed by another company, arranging styling for us, advertising and open houses. Her enthusiasm and professional attitude made the sale relatively painless and the outcome was fantastic. I would have no hesitation in recommending her to anyone wanting to sell or buy.

Diane Schultz

" An outstanding agent "

Deb is an outstanding agent and a true professional. She is dedicated, working long hours responding to all the prospective purchasers and keeping us fully updated of all inquiries and inspections. We couldn’t be happier with the outcome as our house sold within 4 days and at a price which exceeded our expectations. Deb is a delightful person and a pleasure to work with and we absolutely recommend Deb to anyone looking to sell their property.

Rodney Green

" One in a million "

Amazing, one in a million agent! I met Deb whilst she was selling one of our neighbour's properties and there was just something about her that made me think if ever I need to sell my place, she is the agent I want. Deb is such a pleasure to work with, she is genuine and caring and does everything she can do her for clients. She has gone above and beyond with what she has done for me with selling the property. If you are looking at choosing an agent with the whole package, look no further Deb is the one to choose.

Danielle Lott

" Found a good buyer "

Deb was very professional and was really keen in selling our property. From the time we met Deb in her office, she took us through the process of sales and was very confident that she can sell our property. It was tried by 2 other local sales agents but they gave up and we only ended up losing our money. But Deb was consistent in her work and found a good buyer for the property. We really appreciate her consistent hard work, professional ethics, politeness with clients, and her quick response to emails and messages. We highly recommend Deb from Castlehaven for buying or selling of properties. We wish her good luck with all her future endeavours.

George and Ann

" Impressive service! "

Deb is very committed to ensuring the best result. Very hardworking, in fact Deb was most willing to give private viewings in addition to the open houses in order to provide opportunities to as many potential buyers as possible. Nothing was too much trouble. Very professional attitude, friendly and helpful with advice, skillful at qualifying potential buyers. Our family has used Deb before and we will do so again. We would recommend that any seller considers using her services.

Nigel Saunders

" It has been a pleasure to sell my apartment with Deb "

Deb has been a fabulous agent to work with. She has a positive outlook and a "can do" attitude and has persevered for several months until she got me the buyer I was looking for. I really appreciate the fact that she has been so approachable through the stressful process of selling, and has always kept me in the loop and taken the time to explain things and debrief me after each appointment/viewing at my apartment. There were many days when she has worked way past "normal" working hours, and been in touch with me late in the evening, just so that I do not worry about things all night. Her customer service is excellent and she is friendly and professional at the same time - and most importantly - gets the results you want! I would highly recommend DEB NEWTON as a fantastic sales agent to anyone who wants to sell their property in the HILLS area.

Qiana Irani

" Wonderful agent, attentive and helpful "

Deb was wonderful from start to end of my sale. Deb kept me informed the entire time, she was patient with all my questions and I’m thrilled I chose her as my agent. I met Deb at an open home I attended and I knew I wanted her to sell my place. She was sincere and reliable the entire time. I would highly recommend Deb to anyone selling their home.

Michelle Inskip

" Very nice and warm hearted "

During the selling of my property, Deb devoted great effort trying to tackle all kinds of issues from tricky tenant to troublesome repair works. Fortunately everything sorted out fairly good thanks to her effort.

Jue Wang

" Excellent service! Beyond my expectations! "

Deb is very professional and sold our porperty in the first week with a price beyond our expectation! During the sale of our home she constantly kept us updated and was always a phone call away. Her knowledge, experience and honesty makes us feel very secure and comfortable in the process of selling and buying at the same time. I will definitely recommend Deb to anyone I know who is interested in selling in the future as she is simply the best!

Rose Song

" An exceptional, caring and professional agent "

Deb came highly recommend by our neighbours, who had recently sold and she proved to be an exceptional, dedicated and professional agent, who always put our needs first. She is a friendly, genuine person and although we were unsure and hesitant at first to list our property, Deb was patient, fully supportive and positive throughout. Deb went above and beyond in her role, walking us through the process, listening to our needs and giving valuable advice. Her commitment was clearly evident through her long working hours and she is truly knowledgeable about the market. As a result 80 groups attended our open house in two days and it was sold, above our expectations. Deb continued to stay in contact throughout the settlement period and we would strongly recommend her and Castlehaven to anyone considering listing their property. Thank you Deb.

Robert & Sandra

" Professional and experienced "

Deb is the consummate professional. Her client engagement skills are brilliant. She is transparent and displays a high level of integrity. Deb worked the property hard and her activity levels and feedback was frequent and accurate. Deb worked around the clock. She has to be one of the best real estate agents to deal with in the Hills. Really chuffed we engaged Deb to sell our family home.


" What a star "

We decided we were going to sell our house about a year ago and had Deb come over to discuss, but it was put on the back burner due to our circumstances. Three weeks ago we decided the time was right to sell so had Deb come over again to complete the contracts, organise photos etc on the Wednesday. This was done and within 2 days the house was on the market and the first open home was on the Saturday. We had an amazing open house with 36 groups through. The next week we had numerous private inspections and the following Saturday open home we had another 31 groups through. Deb really did her homework in getting people interested in the house and we felt sorry that she was so busy with the enquiries but she took it all in her stride and kept us informed of what was going on. Deb is extremely hard working and never stopped even on a Sunday. Deb is a true professional who is honest and knows the market, knows the area and we would recommend her to anyone who is wanting to sell their property. Thank you again Deb we really appreciate all that you did for us and selling the house within 2 weeks you are a STAR.


" A fantastic real estate agent! "

Deb is a fantastic real estate agent. She is patient, consistent, humble, and most important, professional. She is a person you can trust and hand your keys to. If you are looking for a happy ending selling your house, Deb is the one you need!


" Thank you Deb "

It was a real pleasure dealing with you. You seriously enshrine the principle of integrity & truthfulness as you mentioned in your profile. I am grateful that you arranged private inspection, kept in touch & allowed a building inspection even before entering the cooling off period.

Hitesh, buyer

" Ultimate professional "

Deb Newton is the ultimate professional. Deb has assisted my family several times since we moved to the Hills. Deb has a vast knowledge of the area and has always provided sound advice. I could not recommend her more highly.

Fiona McDonagh

" Just awesome! "

Deb and the team at Castlehaven were fabulous. Without a second's hesitation I would use Deb & Castlehaven again. Nothing was too hard, fabulous connections to help me with the sale, great communication keeping me up to date as things happened from day to day. Highly recommended! Thanks Deb and Team!

Peter & Judy

" A humble realtor! "

It is a rarity to find an agent who is hungry to sell a property at an optimal price but is just as humble. Deb epitomises what a realtor should be. She is persistent but not pushy. She is realistic with a positive attitude. And she never gives up. When picking an agent, ask yourself – Can I trust giving this agent a key to my house? Would I want to have a coffee with them? Do I trust them with my biggest investment? The answer is YES, YES, and YES when it comes to Deb. She surpassed all our expectations and I would happily recommend her to family and friends. Deb made a stressful process, easy. She made us feel comfortable and guided us through a daunting time to sell and buy – COVID-19! When it comes to Deb, you don’t just get a realtor, you make a lifelong friend.


" Great result "

Deb and the Castlehaven Crew are Excellent! From the first open home to the completion Deb has been brilliant in keeping us informed and guiding us through the entire process. The home required an experienced and professional agent which is why we picked Castlehaven and they smashed it out of the ballpark.


" Seamless - easy "

Having Deb sell our new build was an easy choice. Deb always follows through with quick responses to any questions raised. Deb has a great deal of knowledge of the area we were selling in. Easy choice using Deb and Castlehaven Realtors. Great result.


" Sale of our house "

Very pleased with Deb's professional approach to selling our house. We recommend her to others.

John & Sharon

" Excellent service "

We bought a property from a vendor represented by Deb. Deb was responsive and went out of her to way to answer all our questions about the property. She ensured that all communication between the parties went smoothly and she made the whole process pain free. All in all, she contributed signicantly to the successful settlement of our new home.

Jing & Jia, buyer

" Excellent Result "

We found Deb great to work with. Very positive and offered fabulous feedback from prospective buyers. We would recommend Deb & her Castlehaven team.

Wayne & Linda

Deb - what an amazing job you did. Sold our home in less than 1 week. We have used Castlehaven & Deb twice now & can't thank them enough. Delivered well above our expectations in all areas both times. Excellent communication, so helpful, nothing was a problem for them. Simply the best ! Thanks so very much.


" We had complete confidence! "

Deb was fantastic! From our first meeting we had complete confidence in her and her team. She was always on time, professional and went over and above to help us sell our home. Deb sold our home in 2 days for a price that exceeded all our expectations. We are delighted to recommend Deb to anyone wanting an excellent, trouble free experience when selling their home.

Neil & Wendy

" Very honest person and a pleasure to deal with "

I would love to give Deb 10 stars as she is a very honest person and a pleasure to deal with, I would recommend her and her team highly. I have been in business for 28 years, honesty, passion and dedication is what she demonstrated. To me service is a key item in business and delivering what you you promise is very important, Deb did this! It was s pleasure buying from you, Thanks again.

Giovanni & Anna, buyer

" Deb was fantastic "

Deb was fantastic from start of the process right through to the end always updating me throughout. I certainly would recommend Deb to anyone who is thinking of any kind of real estate sale. I know I would use Deb's expertise again.


" Very Professional and cordial "

Deb is very professional and cordial. She supported us happily through multiple valuation and inspection visits prior to sale and with multiple queries for the seller through and post purchase even. Very responsive and easy to work with.

Thusshar, buyer

" I recommend Deb and the Castlehaven Team! "

I wanted to write and thank you for the very professional approach you took to the sale of my property in West Pennant Hills. I am living interstate and was delighted to find communication and the entire process was effortless and well co-ordinated by your agent Deb Newton. Deb had been recommended to me and I really must say, I met with her just once and everything else was done through regular and very pro-active phone and email contact from Deb. It really felt like I was right there beside her and I cannot commend her approach highly enough. I would not hesitate to recommend Deb and the Castlehaven Team to anyone looking to sell a home in the Hills' District.


" We bought a house with Deb and sold the same house with Deb 10 years later. "

I had the pleasure of meeting Deb in 2009 when I requested a viewing of a home she'd listed online only that afternoon. Deb wasted no time, and organised a viewing the same afternoon. We put in an offer and Deb liaised with both parties to agree on a price. Fast forward 10 years and we were thinking of selling. Having remained in contact over that time, Deb was able to offer some practical advice. There was timing to consider and repairs to be made to the house, and Deb took the time to understand the situation and took a proactive role in simplifying the process. Unlike other agents, who insisted we undertake repairs and wait until a better market time to sell by auction, Deb utilised her database to market our property discreetly to potential buyers who were interested in this very specific opportunity. As I'd come to expect of Deb, she sold our house quickly and without any complication. She worked seamlessly around our very limited available time and made the process of selling our home (which is said to be one of the most stressful times of ones life) simple, stress free, and fast. And saved us the the huge process and cost associated with presenting the home to suit an agent's preferred way of selling. To top it off, we sold for a price that met our expectations and the market. I would recommend Deb to anyone selling a property. Especially if you require flexibility and support from your agent.


" Would surely recommend Deb for her excellent expertise! "

We had a great experience with Deb. She was very honest and sincere throughout. She was always approachable and friendly to talk to. Would surely recommend Deb for her excellent expertise!!


" Purchase of property "

Deb made it too easy for us to see properties without hounding us or being a salesperson. Pleasure to do business with. Was prompt, on time and with sufficient follow-up to make us feel special.

John & Sharon

" Good very helpful "

Good Very helpful Approachable

Ranju & Jolly

Deb and Colin were a pleasure to work with Selling your home is a stressful and daunting task. Subsequently, it was a pleasure to have the support of Deb and Colin through the process. Their professionalism and expertise shone through every stage. They were sensitive to our wishes and we always felt we were in “good hands”. We would definitely recommend them to anyone who is about to sell their home.

Helen and Tom

Professional, friendly and ‘always on the ball’. From the time we approached Deb Newton she gave great advice on presenting our property for sale, as well as great contacts to help us achieve it. Deb kept us up to date on the advertising and sales process, and when we received offers she provided great support and advice. This friendly and professional service continued right through the ‘cooling off’ period to settlement day. Couldn’t be happier with the process, and the outcome. Highly recommend Deb at Castlehaven.

C Brook

Above all we appreciated Deb's honesty We met Deb Newton about 20 years ago and have just moved from Kellyville. We had a number of friends who had used Deb's services both to buy and sell properties so when it was time for us to sell it was an easy decision to list through Deb. We had a great experience. Deb helped us position the property, developed a sales strategy and we achieved an excellent outcome. We loved her regular communication and valued her in-depth knowledge of the market, and above all we appreciated Deb's honesty and how we really felt we were working with a professional.

R O'Brien

Honest and professional agent!  I was very impressed with the service I received while working to sell our home with Deb from Castlehaven. I first heard about Castlehaven through some promotional leaflets in our letterbox and I’m so glad to have found and worked with a local agent who is both honest and professional. Deb made regular visits to us to ensure we understood exactly what was happening and kept our personal needs in mind when negotiating with the purchasers to ensure the sale was the very best result for us.


Great agent Great agent …. would recommend them to all my friends.  Great job to Deb and the team!

Bev H

Very Experienced Agent Usually selling a house is a stressful experience but because of Deb's extensive experience in the real estate industry this was not the case. I found her to be friendly approachable and very helpful. She went above and beyond her normal duties to help me, and as a result I was able to get top dollar for my property. I would have no hesitations in referring Deb to any of my friends and family.

L McGuffie

Deb was always courteous and supportive I wanted to thank you for your professional service when we purchased a property recently through Castlehaven. Your agent Deb Newton was always courteous and responsive to any questions we had or help we may have needed. Deb was very supportive to us as we navigated building inspections and other matters of due diligence. It is a pleasure to work with a professional of this calibre.

Robert Hickson

We were very happy Friends of ours had sold their home with Deb Newton previously and were very happy with how everything went so, we’d made contact with Deb before we were even thinking of selling. When we did finally decide to go ahead with the sale of our home, we got in touch with Deb straight away. She saw us through the entire process and found genuine buyers who were interested in the careful renovations we’d done to our home. Nothing was too hard for Deb and she kept us informed of everything the whole way. It was great to have the house sold within three weeks and we were just very happy with the whole process.

D Rimmer

Deb really helped us understand each step of the sale process Selling our Baulkham Hills property through Castlehaven was very easy and stress free. A friend referred us to Deb Newton and they had been very happy with her, so that was a good enough recommendation for me. From the moment we met Deb she was really friendly, understood us and shared our philosophy around the sale of the home. Deb really helped us understand each step of the sale process and was a fantastic communicator – giving us reasons and information about why she was making particular decisions and recommendations. I also really like the Castlehaven philosophy of giving back to the community and appreciate that it is owned and run by Hills’ District real estate professionals. I wanted to thank you for this excellent real estate experience.

Megan Howdle

" We will be letting all our friends know about your excellent service "

I wanted to thank you for the professional service we received when we set out to sell our apartment in the Atmosphere complex. We were delighted with the friendly, honest and hard-working attention we received from your agent Deb Newton. We will be letting all our friends know about your excellent service and attention to detail.  Thank you again for making the sale of this apartment a smooth and simple process, plus one with such excellent results.

" I recommend Deb and the Castlehaven team "

I wanted to write and thank you for the very professional approach you took to the sale of my property in West Pennant Hills. I am living interstate and was delighted to find communication and the entire process was effortless and well-coordinated by your agent Deb Newton.  Deb had been recommended to me and I really must say, I met with her just once and everything else was done through regular and very pro-active phone and email contact from Deb.  It really felt like I was right there beside her and I cannot commend her approach highly enough.  I would not hesitate to recommend Deb and the Castlehaven Team to anyone looking to sell a home in the Hills' District. 


" We had complete confidence "

Deb was fantastic! From our first meeting we had complete confidence in her and her team. She was always on time, professional and went over and above to help us sell our home. Deb sold our home in 2 days for a price that exceeded all our expectations. We are delighted to recommend Deb to anyone wanting an excellent, trouble free experience when selling their home.

" Deb Newton provided a personalised, hands on experience and was available to talk to at any time "

What a professional. Deb's knowledge of the real estate market and Hills region was impressive. Even with her professional approach to sales I felt as though she was with us every step of the way. Negotiating at all hours, flexible with open homes and inspection dates, Deb kept us informed on each possible buyer and explained the website market research patiently. I would not hesitate to recommend her or the agency and will definitely use her services in the future.

" I can only say good things about Castlehaven & Deb in particular "

I wanted to write and thank you for your help selling our home. I can only say good things about your firm, and Deb in particular. Deb was always ready to answer my questions and was honest and genuine to deal with – I regard her in the highest esteem.


" Deb is a standout "

Deb was a standout & to our surprise the marketing costs were included. We sold our Castle Hill home within a fortnight, from the day it came on the market until we accepted the offer completely. I wanted to thank you for the service we received from the Castlehaven team during this time. Deb Newton was a stand out in terms of leading us through each step of the process. Deb was approachable, realistic and committed and she was always available with answers and advice.  To our surprise, the marketing costs were included free for us which was a welcome advantage. Through the entire process we just felt confident we were doing the right thing and the fact we achieved a sale before Christmas was great and a result of Deb’s hard work. I believe the Castlehaven agency is very much about building long term relationships with clients and if we ever had to sell again, we would certainly come back to your excellent team.

" I trusted Deb "

I felt confident to trust Deb with the sale of our family home I have known Deb Newton for more than 30 years and felt confident to trust her with the sale of our family home in Castle Hill’s Knightsbridge Estate. I have always found Deb to be honest, hardworking and competent and through this process she did not disappoint. Deb is a very trustworthy person and I’m thankful to have been able to work with her and your team at Castlehaven through this process.


We sold our last home with Deb and knew exactly who to call when we decided to move I wanted to let you know how delighted we were following the sale of our home with Castlehaven. We sold our last home 13 years ago with your agent Deb Newton and when we decided to move from Castle Hill to a newer home in North Kellyville we knew exactly who to call. To put it simply; deciding to list with Deb again was a “no-brainer”.  In fact, the minute we decided to sell again we went straight to Deb because she had been absolutely fabulous in the past and in true Deb Newton style she has gone way above and beyond for us again. I’d also like you to know how skilful Deb is at handling delicate situations. I like to call it “politely honest”. We knew there were areas of our home that needed attention if we wanted to present well to buyers. Deb let us know exactly what we needed to do in a kind but clear way so we knew what changes to make but were never offended. It’s the little things like that which I have always really appreciated. It’s wonderful to see Deb has grown in her role at Castlehaven and is now General Manager – we dealt with a few of your other staff through the sale process and noted they were equally polite and enthusiastic in their dealings with us. It is great to see this standard applied across the organisation. Finally, I wanted to touch on your agency’s unique offering regarding sale of existing homes and purchase of new homes in the North Kellyville precinct. This was a defining difference for us from all other agencies as we were able to hold our wonderful new home for just $1000 while Castlehaven completed the sale of our existing property. This was a huge advantage and gave us peace of mind that we would not miss the new home of our dreams while our existing one finalised. It also avoided messy finance extensions with banks and other agencies. Glenn, this is an amazing offering that really makes a big difference to families looking to move into a new home. Thank you Castlehaven for making this whole process so easy.

We have always found Deb to work with integrity We were very happy with the service and help we received when selling our Kellyville home through Castlehaven.  We worked closely with Deb Newton who sold a home for us 16 years ago and we have always found her to be someone who works with integrity. Deb was professional and honest in the market appraisal of our home and we appreciated that she set realistic goals and valuations for us to work towards. As always, Deb also offered excellent customer service to us during the marketing of our home and it is wonderful to engage with an agent who is committed to achieving not just a sale but also a happy customer. We believe Deb worked very hard to support us through the sale of our home and negotiate the best price possible for us.

Deb's warm & happy personality made selling a breeze Thank you so much Castlehaven for the amazing service you offer to people selling their homes in the Hills area. We recently sold our home in Kellyville through Deb Newton and her warm and happy personality made this very busy process a breeze. Working with Deb, I had every confidence that she had taken care of everything and we were delighted when the home sold within a week for a great price. Deb and the Castlehaven team made sure everyone who should know about our home did. In the first week, we had more than 20 people inspect the property and it was great to find a genuine buyer from among this group. I would certainly recommend Castlehaven to anyone because it is such a smooth and well managed process.

Joyce Giles

Trustworthy and well informed I was delighted with the way Deb Newton managed the sale of our Castle Hill home. I have known Deb for some time and found her market appraisals and general approach to her work to be both trustworthy and well informed. When it finally came to selling our home, Deb was the natural choice. She generated strong interest from genuine buyers with six people through on the first day. We sold for an exceptional price within 5 days of listing. Deb was attentive throughout the process and always returned calls promptly. I would happily recommend Deb to other Hills District home owners.

A stress-free sale I wanted to thank Castlehaven and, in particular, Deb Newton for the expert way you handled the sale of our Kellyville Ridge home. The last time we sold a house was 17 years ago, so we really had no idea how it would all work because it was so very different back then. Deb was fantastic, she just made everything stress-free and put us at ease every time there was something we weren’t sure of. Castlehaven’s extensive database of clients really helped too. We had strong interest in the property from day one and it sold at the first open home so we couldn’t be happier.


Deb found several interested buyers I’ve had had a long relationship with Castlehaven as both a seller and purchaser of properties over the years and I have always been very happy with the service and professional standards they offer to clients, particularly when dealing with them as a seller. I have always found Castlehaven staff to be very friendly, professional and extremely fair in their fee structure for the sales they achieve. I recently sold a two bedroom apartment with their Sales Manager Deb Newton who I have known for many years. Deb continues to impress me with her no pressure sales technique in introducing prospective purchasers and in particular the professionalism she always demonstrates.   In a very difficult market, Deb managed to find several interested parties and we were very successful in the way we ultimately sold. I believe Deb’s no pressure manner contributed greatly to this success. As vendors, we valued the extra efforts made during the sales promotion period, which included newspaper, online and letterbox advertising. We feel this made a real difference in generating interest about the property we were trying to sell, with extremely positive results compared with others trying to sell in the same building. I would have no hesitation in recommending Deb Newton and Castlehaven to others looking to buy or sell a home in the Hills District.

Honest, informed, approachable I wanted to write and share how happy we were with the service we received after deciding to list our long-held family home for sale with Deb Newton from Castlehaven. Deb was the consummate professional from start to finish and when we required help or advice nothing was ever a problem or too much trouble. We found Deb to be honest, informed and approachable. We were very happy with the service she offered us during the sale of our property and would have no hesitation recommending her to others.

Rob Mayo

Excellent experience selling with Castlehaven We recently decided to sell our family home in Castle Hill, where we had lived for more than 30 years. These decisions are never easy but I’d like you to know we had an excellent experience selling our home through Castlehaven. The staff clearly had an amazing knowledge of the local area – finding a buyer from their database, negotiating for a price that suited us and closing the deal without any advertising or the hassle of open homes and people traipsing through at short notice. Exploring what the market had to offer us and then securing a very good price was, for us, a great success thanks to the expert sales management of Deb Newton. I was so impressed with Deb’s warm and honest approach and would not hesitate to recommend her to other locals looking to sell their home. I also really valued the way the Castlehaven agents worked as a team to get the best result for us. Deb worked with sales agent Dave Mills to find just the right buyer for our home. Dave was able to let people know our home was quietly on the market and actually introduced the eventual buyer to the property. The end result is a young couple able to start a life together in our old home and a fresh start for us in a smaller property that will be much easier to maintain. Thank you for providing such wonderful service to families looking to buy and sell in the Hills District
