We'd met Mark a few times whilst living in the area and knew of his reputation in the market. Our initial call to discuss the selling our house was after we had relocated overseas. Within a few days Mark provided a proposal that was competitive, effective and met with our expectations. The high level of service continued throughout the entire process, being abroad was no disadvantage as Mark managed the pre-sale preparation of the property right through to hand over at settlement. Highly satisfied with Mark and the team at Richardson and Wrench Castlecrag. Kirsty and Vincent

Mark is a highly professional and dedicated agent. He has a high level of integrity and kept us well informed throughout the sales process. We would highly recommend Mark O'Brien to others considering selling their home.

When I first even contemplated that I might sell my house, knowing how much preparation of that house was going to be needed, Mark kindly spent the time addressing that process and where he could contribute. Once the decision was made, he promptly arranged for the various trades people to attend to the required remedial works, and I was impressed by the speed and quality of that work. I could not have hoped to achieve that by my own dealings. His feedback during the marketing phase of the sale was honest and was kept right up to date with what was happening.

It was a pleasure working with Mark, who understood the house as a proposition from the buyers point of view and managed the process with skill and with a satisfactory result.

After living in Castlecrag for 15 years we made the decision to make a tree change and retire to Berry NSW. It was important to us to sell our much loved, beautiful home with integrity and for the best price possible. We discussed our plans with several local agents to determine who would be the most professional to deal with and Mark O'Brien proved to be the obvious choice. Prior to commencing the marketing of our property Mark provided us with valuable advice on items at our home that we should improve in order to maximise both the appeal to potential buyers and the sale price. Throughout the entire auction campaign, Mark kept us fully informed of the progress with prompt and honest feedback. Our home sold one week prior to auction for an amount that exceeded all our expectations. Mark is a man of integrity and honesty, these are qualities that are very important to both vendors and potential purchasers at the challenging time of buying and selling real estate. We knew that potential buyers would be as comfortable as we were to trust Mark to tell them the facts to allow them to make informed decisions regarding the purchase of our home. If you are looking for the best agent in the Castlecrag area to sell your home for the best price - Mark O'Brien is the agent for you.

Mark O'Brien's depth of market knowledge and experience is unmatched in Castlecrag. We found his excellent advice to be a very rare blend of the commercial and personal. Mark is a person of high standards and integrity and we would unconditionally recommend him.

I have done business with Mark for a few times and he has been acting extremely trustworthy every time. Some time he has advised me something not necessarily benefit him but he stands on the clients' side to recommend what is the best. In the long run, this sort of attitude will win the credibility and let people like me feel doing next business again with him in future.

Thank you so much Mark for your professionalism and overall skills. We have now purchased 2 houses through you and sold 1!!
