Above and beyond

We sold our property in Dulwich Hill earlier this year and couldn’t have asked for a better agent than David Diamantopoulos. From start to finish, David was relentless in his effort, focus and professionalism. He never gave up, he never pushed low-ball offers our way, and he worked tirelessly behind the scenes to get us the best possible result in a challenging market. This was our first time selling, and David made the whole process feel clear and manageable. We never once felt silly asking questions — he was patient, honest, and always had our best interests at heart. His communication was spot-on, his advice was trusted, and his commitment went well above and beyond. Most importantly, we genuinely felt he cared. We trusted him completely, and that trust paid off. If you’re selling in the Inner West, we couldn’t recommend David more highly. He’s exactly the kind of agent you want in your corner.

The wonderful experience for first time sellers.

The wonderful experience for first time sellers.

We recently had the pleasure of working with David and Poppy from the agency to sell our childhood family home. A property that has been in our family for almost 100years. From the very beginning, David and Poppy were understanding and empathetic to our situation. They listened to the type of presentation and campaigning that would best suit us as we prepared our family home to sell. Their knowledge of the inner west particularly the Dulwich Hill and Marrickville area was evident through their bulletins and portfolio but the knowledge of the market and ability to source buyers particularly interested in the property we had to sell was ultimately remarkable. When the campaign started, David and Poppy were amazing. They were open and honest with feedback from potential buyers through phone calls and they shared the reports from real estate.com and domain which I found very interesting. On auction day, it ran like the campaign, extremely smoothly, with a successful outcome we were all very happy with. David and Poppy truly are the dream team. Their understanding and expertise of not only the area but our individual situation along with their hardworking commitment to the best possible outcome was a godsend. We would most definitely recommend this power couple and would use them again in a heartbeat.

Aaron demonstrated professionalism, courteousness and focusing on a successful sale.

We recently sold our property in Marrickville through The Agency at Marrickville/Dulwich Hill. We have nothing but praise for Aaron Papadimatos, The Agency's property partner, who managed the sale. At all times, we found Aaron to be professional, courteous, and considerate of our interests and expectations. We cannot fault the approach he took to the sale of the house that had been our family home for more than thirty years. Aaron demonstrated a sound understanding of all the challenging decisions that this involved. Aaron also supervised the completion of repairs, decisions about presentation of the property, and the choice of auctioneer to maximise our return.
