Greg was a confident and incredibly capable ambassador for my home in Castle Hill. He quickly identified the target market for my home and gave me comprehensive advice about how to best prepare it for sale. I followed his advice and reaped the rewards when the sale price and terms exceeded my expectations and also surpassed sales of comparable properties in the suburb. If you are looking to sell in the Hills, Greg and the Opes RE team are the best people for the job. The level of service is fantastic and their advice is spot on. They genuinely care about their vendors and this is rare. Thank you Greg for a great experience.

Both my wife and I found Greg to be very knowledgeable about the real estate market within our neighbourhood and surrounding area. He also demonstrated a deep understanding of the buyer market and the mood of that market. Greg is extremely personable and repeatedly demonstrated how easily he was able to associate and understand our needs and the needs of the buyers, which he used to enhance the process of selling the property. This attribute went a long way to making the process of selling the property as smooth as possible and a little less stressful. Greg is also an excellent communicator; he consistently communicated in a fashion that best suited us. Greg also understood the buyers and used this knowledge to connect with them in the appropriate way, which did not stifle them and artfully turned negotiation into a sincere and respectable conversation leaving all parties feeling valued and supported. Throughout the entire sales campaign Greg cleverly managed both our expectations and as well as those of the buyers, ultimately, we achieve a sales price that we were comfortable with. Well done, Greg, an excellent result, and a stellar performance.

We were selling at a difficult time for the market. Greg and the team at Opes RE were always honest, kept us informed and worked hard to get us the best price. It was surprising to see how much they were willing to go “above and beyond” to support us through the process. A great team delivering a great outcome!

Thank you Greg and his team. Excellent knowledge, responsiveness and transparent. It was a pleasure working with Opes RE team. We are very happy with the entire buying process from showing to settlement.
