Positioned in the heart of San Francisco's prestigious Cow Hollow neighborhood, 1964 Union Street is a prime multi-family investment with both immediate income strength and compelling long-term upside. The property features well-maintained, recently updated residential units, many with modern finishes. While the building is turnkey from an operational standpoint, there remains significant upside in rents, offering investors the ability to capture stronger cash flow as leases roll. Beyond the stabilized income stream, 1964 Union Street includes a large, flat, vacant rear yard that presents an exceptional development opportunity. Whether for additional units, an ADU expansion, or enhanced common-area amenities, this underutilized space offers investors a pathway to unlock further value in one of the city's most supply-constrained neighborhoods.
