Another 5 star review for the best in town!

Stephen is by far the most professional, experienced and personable agent we have ever come across, and I've worked in the property sector for over 20 years. We appointed Stephen and the team at Bresic Whitney to divest of our rental unit in Crows Nest, where he has achieved a record sale for the block and within a few days of listing. An amazing result and we are over the moon! His integrity, diligence, thorough and continued communication throughout the process is unmatched in the industry. He maintained a line of contact over many years, providing regular updates and honest opinions on the market conditions, views on timing and how to present the property for sale. His attention to detail, approach to the marketing and positive energy saw us achieving a result beyond what we could have possibly imagined. We can't thank Stephen and the team enough for the result. The process was incredible, always showing us a high degree of respect and being mindful and considerate of our current circumstances. He genuinely managed everything on our behalf such that there was no stress or delay in getting our dream result. It goes without saying, Stephen and the team at Bresic Whitney come highly recommended for any property sales, particularly in the lower north shore where Stephen has a knack for achieving record results. He understands the market better than anyone. His integrity and trusting approach is key to his success with finding the right buyers. He is truly a winner in our eyes and we wish him all the best with future sales. We will certainly be recommending his services to others and be a return client for future properties!

Amazing and stress free!

I’ve been looking for a property for close to two years and in that time I’ve met a lot of agents. Through that journey, Stephen has always stood out as a genuine and trustworthy agent. You could tell that he had the interests of both the vendors and the prospective buyers. He was super helpful and because of him, it was the most stress free experience I’ve had in this first home property hunt journey.
