Exceptional value-add multifamily opportunity in the heart of San Francisco's Mission District. 3660 20th Street is a five-unit building offered at $1,350,000 ($270,000/unit, $350/SF), featuring a strong unit mix of (3) two-bedroom units, (2) one-bedroom units, and a non-tenant-occupied garage providing ancillary income free of tenant protections. The 3,862 SF building sits on a 2,866 SF lot and currently generates $7,113/month against estimated market rents of $19,000/month approximately 167% upside to gross scheduled income.

Originally acquired through a trust sale with historically below-market rents, the asset offers a clear path to stabilization through organic turnover and targeted renovations in one of San Francisco's most supply-constrained submarkets.
