Selling my Property

Mark did an outstanding job on selling my property. He was so understanding, knowledgeable and showed such a determination in selling my property with confidence whilst showing such support and care during this difficult time in my life. I Highly recommend Mark Griffin as your chosen agent in selling your property.

Mark is a spectacular agent.

He went above and beyond to assist me in my role as an executor of a deceased estate. I have found him to be genuine, diplomatic and solutions focused. We would not have achieved such a pleasing result at auction if it was not for his expertise and determination, not only in his negotiations with buyers but in preparing our property for market.

We have bought and sold through Mark, Chyna and...

We have bought and sold through Mark, Chyna and the team at Belle on numerous occasions now and wouldn’t use anyone else. The team are such a well oiled machine. It was such a stress free experience and we had full trust in their capabilities, professionalism and skillset to get the best price possible which they did on both occasions. Thanks so much to everyone involved.

I have had a professional relationship with...

I have had a professional relationship with Mark Griffin for over 20 years, even before he joined the Belle team. My previous experience with Mark and Belle led me to seek no appraisals from alternative agents, and I was not disappointed in that course of action. His predictions regarding the course of the campaign and subsequent auction were uncannilly correct. I couldn't be happier with the outcome.
