" Many agents forget they are selling a home "

Stephen, Thank you for finalising the transaction for Fashoda St within our timeline and for your considerable time spent with Dad whilst viewing the property. Many agents forget they are selling a home…..not just a house, allowing people time to connect with a home is key to achieving a good sale & really critical especially in Dads case when he has been in his current home for nearly 40 years! Cheers Andrew


" Unbelievable! So good! "

We were so fortunate to have found Stephen Ong when we decided to sell our houses. He has excellent market knowledge and look after customer very well. He was immediately responsive to our questions to help us in making a decision. We sold our two houses in eastern suburb within one month after we post the advertisement. He got me a sale of the price we wanted. We feel we have a trustworthy agent, as well as a friend! We think the best part is that we now have a new friend. We would highly recommend him.

" Great agent "

I shop around & the first time I meet Stephen I knew I had the right real estate agent. I couldn't have made a better decision. Just made me feel so confident with every decision I made with his help thank you so much.


" Stephen Delivers Results "

Stephen did an outstanding job in selling our property. He conducted himself very professionally from the initial meeting and through the whole process. All our questions were answered with clarity and he offered much needed advice in a very timely manner. Stephen worked hard for us, always with a smile and a 'nothing is too difficult' attitude. Punctual, dependable, prepared...he was a pleasure to work with and I would have no hesitation in recommending Stephen as the man to see if you want the best results.

" We can't thank you enough, Stephen "

We would strongly recommend Stephen Ong to anyone before engaging any other agent or putting their property on the market for sale. He is simply outstanding, knowledgeable and hardworking. Before choosing a real estate agent, I conducted a lot of research to see who would be the best choice based on the investment they make into selling the property (time and effort, not necessarily financially) and how they promote their listings. I had interviewed 5-6 agents, but Stephen Ong stood out as the best has to offer: their customer approach is excellent, their media coverage is wide (covers local and Asian market), their social media presence is strong, and I could tell they put a lot of work into their listings. We spoke with Stephen and then met with him at our home. He spent hours answering our questions, providing objective data regarding how many homes they sell, how long their listings typically stay on the market, and providing tons of info in the area. We were concerned that our house could not sell at our asking price. Stephen made the process incredibly easy and took extra steps many other agents don't (but should), like give us staging tips, having professional photographs taken, and a lot more. When we saw our listing we were blown away. His hard work and knowledge of what it takes to sell a home really paid off - our listing looked amazing and knocked out the competition. Our house went under contract after Auction and sold. Stephen walked us through every step of the closing process. It couldn't have been a more pleasant experience. I've recommended Stephen Ong to everyone I know. He's a true professional and a genuinely nice guy. I realize it won't always be this easy to sell your home, but I think you'd be hard pressed to find a better Agent.


" His enthusiasm in helping the buyers achieve a dream "

Stephen communicated very well through the process. He was able to negotiate very well with the clients, and balanced the interest of the buyers and vendor very well. His enthusiasm in helping the buyers achieve a dream, was well reflected in their satisfaction in the product!



Stephen and his team ran an excellent marketing campaign and sold out all 5 properties. The sale price far exceeded our expectations. He was happy to answer all of our concerns and was thoroughly professional in all of his strategies and recommendations. We would have no hesitation in recommending Stephen and Team Sinova to sell your property.


" First class negotiator "

Choosing to go with Stephen’s team was the best decision we made. His knowledge and dedication to get us the best price possible in this tough condition leads to an exceptional result we couldn’t be happier. Especially how he negotiated on the Auction day to get the best price out from the buyer. Huge thanks to Stephen, Jonathan and the Sinova Team.


" Very Professional Agent "

Actually we found working with Stephen Ong to be a hassle free experience. Their communication with the 3 lots of vendors was excellent; also requiring some coordination, as one lives in Tasmania, one in country S.A. and one in Adelaide. Updates were informative & thorough, and I was really appreciative of having a meeting with the auctioneer, the day prior to the auction – We were advised of how the bidding would likely progress and were prepared well for ‘adjustments’ that could have had to be made.
