Trustworthy and Professional in preparing the sale of our property.

Trustworthy and Professional in preparing the sale of our property.

We recently sold our parents’ home through The Agency, with David and Poppy handling the sale. From start to finish, the entire process was seamless, with excellent communication, coordination and professionalism throughout. David’s strong market knowledge and excellent negotiation skills helped achieve a great outcome, while Poppy ensured everything ran smoothly. We couldn’t be happier with the service we received and highly recommend David and Poppy to anyone looking for a professional, stress-free property sale. Thank you both!

Outstanding professionalism and market knowledge

Outstanding professionalism and market knowledge

At a time when there is uncertainty about sale prices, it’s important to have a good real estate agent that is a good communicator. We used David and Poppy, as we have in the past, and they opted for an off-market campaign which was extremely successful. We know they have vast experience and knowledge of the market place and the suburb and it saved a lot of time, money and of course, stress. They achieved the price we wanted and we quickly purchased another house in the same market conditions.

Professional and Committed Agents

We were very impressed with the effort and professionalism of the team throughout the sale of our apartment. Selling in a weakening property market is never easy, but they remained proactive, responsive and committed to achieving the best possible result. They provided sound advice on pricing and strategy, communicated well throughout the campaign, and worked hard to generate interest and negotiate with potential buyers. Their persistence and market knowledge ultimately paid off, and we were very pleased that they secured a good price for us despite the challenging market conditions. We have no hesitation in recommending them to anyone looking for an agent who genuinely puts in the effort, understands the market and is committed to achieving a successful outcome.

Dedicated, Honest, and Always Looking Out for His Clients

David is an exceptional real estate agent who truly goes above and beyond for his clients. From our very first interaction, it was clear that he is highly professional, incredibly knowledgeable, and genuinely people-oriented. His communication throughout the entire process was outstanding—he kept us informed every step of the way, was always available to answer our questions, and took the time to explain everything clearly, making what could have been a stressful experience feel smooth and straightforward. One of David's greatest strengths is his exceptional understanding of the market. He's always up to date with current market trends, and his insights, industry knowledge, and professional experience gave us complete confidence in every decision we made. His advice was thoughtful, honest, and always backed by experience. What truly sets David apart is his genuine commitment to achieving the best possible outcome for his clients. It never felt like we were just another transaction—he genuinely cared about our goals and consistently acted in our best interests. His dedication, integrity, and client-first approach were evident throughout the entire process, and his expertise ensured we achieved an outstanding result. If you're looking for a trustworthy, experienced, and genuinely caring real estate agent who is committed to delivering exceptional service and results, I couldn't recommend David more highly. Thank you, David, for your professionalism, guidance, and unwavering commitment. It was an absolute pleasure working with you.

Great communication skills.

Great communication skills.

David recently completed the successful sale of my unit at Newtown. He personally assisted me at the beginning of the process and gave me full confidence in his ability as my agent. David provided me with excellent advice and regular updates and the sale was concluded quickly and efficiently. I highly recommend David and his team to anyone looking to sell.
