Mosman homeowners don't let go easily, and the data proves it. According to Cotality's Pain and Gain report for the December 2025 quarter, the median hold period for a profit-making sale in Mosman was 12.7 years. That is more than three years longer than the national median of 9.2 years, and above Sydney's median of 11 years.
That single number explains a lot about why buying in Mosman feels the way it does. When owners hold for over a decade on average, the pool of available properties at any given time is small. Homes that do come to market – particularly well-located houses and quality units – tend to attract immediate and serious attention.
For buyers, this means that the window between a property appearing and a deal being done is often very short. Buyers who are not fully prepared tend to miss out, not because they weren't interested, but because they weren't ready.
Ready means having finance pre-approval, not just an estimate, before you start looking. It means knowing exactly what you want, what you’re willing to compromise on and what you won't. And it means working with a real estate agent who knows this market well enough to tell you when to move fast and when not to.
Being connected to the right agent makes a real difference. Whether you're ready to buy or just starting to think about it, our team knows this market and who in it is ready to move. Call us on (02) 9969 7622 or email info@rwm.com.au for a confidential conversation.
