David is a fantastic agent

David Mahony was extremely helpful with advice and deep local knowledge. He was very professional and sold my place with a couple of days. The photos looked amazing. Although very sad to sell my place he made it easy. I thoroughly recommend David to you.

Long-term supporter

My experience with David began 15 years ago when he sold me my apartment. Each year David would send me an anniversary letter congratulating me on my purchase with updates on the progress on the area. When it came to selling my apartment this year (2024) the choice was easy. I chose David because of his knowledge of the area, his kindness and respect as well as his professionalism and commitment to achieving a positive outcome with the sale. I found David straight forward, upfront and clear in his expectations of the property and the current market. At no time did I feel pressured, or faced with hardcore sales tactics. David is a great choice if you are looking for a Real Estate agent in the area. I could not have been happier with his service and support.

Extremely knowledgeable and professional, excellent communication through all stages of the process

David’s market knowledge is thorough, detailed and current. He keeps in regular contact, and everything that he said would happen, did happen. The whole process was quick and trouble free. We are very happy with the whole experience. We have recommended David to others who are also very happy with their experience. Would definitely recommend Green Park Realty.

Highly recommended - Very reliable, professional, honest and and knowledgeable

If you are looking to sell a property in the Newington area I would highly recommend David from Green Park. His knowledge of the area is extensive and he is very down to earth and easy to deal with. We felt very comfortable dealing with David from the very beginning. He made the whole process of restoring and selling our unit as painless as possible, from recommending and organising tradespeople right through to achieving the sale. David was easy to communicate with and always kept us updated after each open house and inspection. He was very honest in his estimate of the price we could achieve and turned out to be spot on. We are very happy with the sales result and it was so refreshing to deal with an agent that is trustworthy and honest.
