Raine & Horne Mosman

Raine & Horne Mosman has been a cornerstone of the Lower North Shore real estate community since Brendan and Shann Warner took ownership in 1995. Growing up in Mosman, the Warners brought an intimate understanding of the area's character, from its Federation heritage homes to the exclusive Golden Mile waterfront properties that define Sydney's prestige market.

Under Warner leadership, the Mosman office has consistently ranked among the top 10 Raine & Horne offices across Australia. With over 40 years combined local real estate experience between them, the Directors have cultivated an enviable network of contacts and a reputation for integrity and results in the tightly-held 2088 postcode.

As part of the Raine & Horne Lower North Shore group, the Mosman team operates alongside offices in Lane Cove and Willoughby under the leadership of Stuart Bourne. This collaboration creates unparalleled market coverage across the Lower North Shore, while maintaining the personalized service of an independent, family-owned operation.

The agency benefits from the Raine & Horne brand — established in 1883 by Tom Raine and Joseph Horne in Sydney. As Australia's oldest family-owned real estate firm and one of the oldest private companies in the Southern Hemisphere, Raine & Horne predates Commonwealth Bank, Coles, Myer, and Qantas. This 140-year legacy provides clients with confidence, while the Warner family's local ownership ensures deeply personal, neighborhood-focused service.
