Sonia Leal

What was the driving force behind Niche Portfolio for the agency’s Principal and Founder, Sonia Leal? It was simple: Sonia wanted to offer better service and stronger value than what she saw other property managers in Sydney’s eastern suburbs delivering. And with more than 20 years’ experience working in real-estate agencies in Sydney’s niche, eastern-suburbs pocket, Sonia was in a good position to know what the market was doing.

In response, Niche Portfolio focuses on handpicking and screening a small database of high-quality tenants for your residential property or commercial property. Sonia makes sure you have a dedicated property manager at Niche Portfolio, someone who closely understands and follows your property’s progress, available out of office hours to suit you. Plus, she makes sure your property manager monitors your rental payments straight away. After all, you are holding a property in Sydney’s eastern suburbs because you’ve recognised the strong returns that this niche part of Sydney can deliver.

We are here to make sure you receive those returns, under the right business model for the residential or commercial property you’ve entrusted to us. Driven by this strong vision, Sonia built Niche Portfolio into one of Sydney’s most personalised and efficient property-management agencies. She thrives on offering that touch of warmth in her property-management service, a magical experience that only a small agency can deliver. Sonia lives and works in Sydney’s eastern suburbs. Niche Portfolio is based in Paddington, an exclusive fashion, hospitality and residential precinct on the border of Sydney suburbs like Woollahra and Bondi Beach.
