John is a very passionate and knowledgeable agent. We have worked with him several times over the past two decades. While anyone can sell a property when the market is booming, it takes more craft and skill to navigate the process more recently as things have softened somewhat. On the most recent experience, he helped manage our expectations to ensure we didn't miss an opportunity and got us a very solid and fair final outcome. John is very experienced and guided us with honest opinions, not by what he thought we wanted to hear. We would gladly work with John again and strongly recommend him to others.

John did a great job when selling our property. He was prompt, courteous and very knowledgeable. His attention to detail was exceptional and I would recommend him if requested.

The agent went above and beyond to accommodate the sale of our property. Attention to detail together with his personal touch and attendance made it easy and Welcoming , without feeling like just another client . Much appreciate the service.

Our time spent with John was relatively brief, but clear cut and effective. He was polite, straightforward, and communicated clearly and seemingly with honesty.

I did not realize how stressful it would be to sell a house at auction;but with the guidance of John Costanzo my feet were kept grounded,the sale was completed and I was very happy with the result. Regards Bernie FitzGerald

John was very easy to deal with, and listened to our wants and needs. Guided us through the process while also setting realistic expectations (this was important to us). Our house went to auction and John was the auctioneer. We were happy that he could also take on this role. We took his advice on board regarding many elements and felt that his recommendations were accurate and had our best interests in mind.

John gave us honest advice. He sold our house very quickly at a price we were happy with. Would definitely recommend him. He would be our first contact if we were to purchase/sell in the area.

John was extremely professional and helpful in the sale

Persistent negotiator between buyer and vendor. A commendable effort in reaching an agreement. Thanks!

John and his team have been a pleasure to deal with in the sale of our property. He is prompt in replying to all queries, reliable and courteous. He is not afraid to provide extra service to ensure the best marketing of the property is achieved. We are happy to recommend John and the team at Chambers.

We recently bought a house through John. I think the sign of a great agent is someone who continues to provide service after the Sale Contract is signed. We were very impressed with John's willingness to help out where he could with all our questions and requests following the sale. We highly recommend him to others.

John sold our property as per our expectations. He is totally professional and honest in his approach - he tell it as it is, which helps you make the proper decisions. He also went out of his way to make sure everything ran smoothly. Highly recommended as an estate agent.
