A very successful and stress free experience for the sale of my unit with Simone.

Simone’s marketing knowledge and negotiating skills are amazing. Her professionalism is second to none and she is always available to answer questions and to spend time explaining each step along the way.Even though she is a very busy person she will always take a call and make you feel important. Simone has made the whole experience a stress free one for me.

Selling the Family home

Selling the Family home

Selling our mum and dad's house (the family home) in such a difficult and unpredictable property market was never going to be easy, but Adrian made the whole process feel manageable from day one. He handled everything from start to finish, always keeping us informed and guiding us through each step with confidence and professionalism. Nothing was ever too much trouble, and his positive, helpful attitude made a real difference during what could have been a very stressful time. He worked incredibly hard on our behalf and achieved a great result despite the challenging market conditions. We are extremely grateful for all of Adrian's efforts and would highly recommend him to anyone looking for an honest, dedicated, and highly capable real estate agent.
