What people are saying

Justine and Brendan recently marketed our house and took it to auction where we had a fantastic turnout and sold that night. They were friendly and professional and put together a campaign that generated a lot of interest. They kept us informed along the journey and were a calming influence when we needed it. They have an extensive knowledge of the Mt Eden and surrounding areas so if you’re thinking of selling, we recommend you give them a call.


It was our first experience selling our home and what can be an extremely daunting and scary process being in the hands of Justine and Brendan was not only smooth but extremely easy and enjoyable. Their friendly, personable and confident approach to our dream was not only their best interest but we really couldn’t have wished for a better duo to guide us through this journey to our next. We are so grateful to have had them throughout this experience.


Thank you so much for your patience and professional handling of our promotion, auction and sale (the end part wasn't easy). We would certainly recommend you both for your outstanding service to anyone considering selling!


We listed and marketed our house in Mt Eden with Justine Koning, a decision that paid off… in bucket-loads. Not only did Justine achieve a price well beyond our expectations, but the sale set a new record for the area. Justine was extremely professional, acting with great integrity. She gave us superb advice on presenting the property, kept us fully informed throughout the campaign and managed the potential buyers with true skill. We are more than happy to recommend listing your property with Justine, in fact we would urge you to do so.
