I have now both purchased and sold property through Mark Costello. When it came to selling my unit, it was a no brainer contacting Mark to be the selling agent. Still, I was blown away by the result. Sold well above asking price, multiple offers, and under contract after just 1 inspection. There were certainly bumps in the road (no fault of Mark or any of the iThink team). From tricky buyer requests, to bond cleaners who didn't show up and even taking care of my cats during inspections; nothing was too much of an ask. I would have been lost without Marks help, and certainly wouldn't have had such a smooth sale. If you want someone to take selling your home seriously, and who goes above and beyond every single time, make sure you call Mark.

From my first contact over the phone, Wayne displayed a genuine caring and positive attitude. He really knows his stuff with regard to real estate especially where the market was and is at. I trusted him totally with how he thought we should handle the sale. We spoke about a plan of action and I felt confident that he would get us the best price and in a timely manner which he did. He kept me informed the whole time as and when things changed. Talking with Wayne was more like talking with a friend but with the professionalism of a real estate agent. I would highly recommend Wayne Hamlet to anyone buying or selling. Thank you so much Wayne 😊

I’ve often been wary of real estate agents—perhaps unfairly—but working with Wayne Hamlet completely changed that perspective. He is genuine, honest, and deeply committed to achieving the best outcome. Wayne guided my mother through the transition from our family home of 60 years into downsized living. He supported every step of the process, consistently going above and beyond—even when it brought him no direct benefit. His approach was professional, calm, and refreshingly low-pressure. He built our trust through clear communication and a straightforward, approachable manner. He was always available to answer questions and provide reassurance during what was a new and sometimes anxious experience for our family. Rather than overpromising, Wayne set realistic expectations around price and timing, then worked diligently to achieve them—ultimately exceeding what we thought possible. He kept us well informed throughout and ensured my mother felt comfortable and confident at every stage. His knowledge of the market, both broadly and locally, was excellent. With limited recent experience in real estate, we relied heavily on his guidance, which he delivered with clarity and care. Even after settlement, he checked in to make sure everything had gone smoothly. I highly recommend Wayne to anyone looking for a trustworthy and dedicated real estate agent.
Buyer of 15 Berghofer Street, Rockville
Wayne supported me throughout the sale and settlement for my new home in Toowoomba. He kept me informed throughout the entire process and even followed up after the settlement. He is a very straightforward kind of guy who is professional, punctual and a gentleman . Would highly recommend Wayne for your next home purchase or sale.
