Review Deidre
over 2 years ago
Deidre is an agent that really knows the market.

When Deidre first came to our property she was very enthusiastic about our home and put us at ease straight away about putting our house on the market when the time was right for us. We had valuations from four different agents and hers was considerably above the other three. But this was not the reason why we picked her. It was because of her knowledge, professionalism and the ease of working with her. The sale price she achieved was in excess of her original estimate, and considerably above the average valuations of the other agents. So if you are looking for an agent who knows the market, is professional and a pleasure to deal with look not further. Thank you Deidre for all your hard work.

Highly recommend Land Agent

We are very happy to tell anyone who needs to sell there house that having Deidre Mastroyannis is an asset to that end. Her communication and professional presentation made you feel confident, yet at the same time you could feel comfortable talking to her without judgement. After a few attempts of getting that sale the right people came along. We thank Deidre very much for her on ball attitude and the chance to start our next adventure. Gayle & Brad

Buyers review

We have recently purchased a property from Deidre prior to the property having a public open inspection. Deidre made herself available via phone and person in a very timely fashion, she was approachable and helpful in answering our questions. We found Deidre to be very helpful post signing of our contract with building and pest inspection appointments and settlement.

Deidre has a very good knowledge of the wine coastal area. We found her to be professional, honest and pleasant to do business with. The transaction was seamless from first inspecting the house to the final purchase. We would thoroughly recommend Deidre in all matters.
