Just Sold | 3 Contiguous Multifamily Properties | San Mateo, CA I successfully closed three contiguous multifamily properties on Grand Boulevard in San Mateo. Each property was owned by a different owner, which added a layer of complexity requiring coordination across multiple parties, timelines, and objectives — ultimately resulting in a successful outcome for all involved. Collectively, the properties featured the potential to construct up to 12 ADUs, per an ADU consultancy’s pre-feasibility study. In total, the portfolio consisted of 10 residential units, 6,369 square feet of building area, and 22,873 square feet of land. Ideally located near Downtown San Mateo, residents benefit from walkable access to shops, dining, and entertainment, along with proximity to Caltrain, Highway 101, and Highway 92, allowing for efficient commutes throughout the Peninsula and Silicon Valley. The area’s strong economic fundamentals, excellent schools, high quality of life, continued rent growth, and ADU optionality made 315, 321, and 327 Grand Boulevard compelling opportunities for cash-flow, appreciation, and development-minded investors. These transactions reflect what today’s buyers are prioritizing: flexibility, upside, and long-term upside in supply-constrained Peninsula submarkets. 327 Grand Blvd | Triplex • Two buildings on one lot • (2) 2BR/1BA + (1) 1BR/1BA • Fully occupied with stable in-place income • 7,651 SF lot with the ability to add up to 3 ADUs 315 Grand Blvd | Fourplex • (3) renovated studios + (1) renovated 2BR/1BA • Two units delivered vacant for owner-occupancy or repositioning • Extensive capital improvements completed • 7,500 SF lot with feasibility to add up to 5 ADUs • Strong blend of cash flow and development upside 321 Grand Blvd | Triplex • Held under the same ownership for 50+ years • All units with private yards • Two buildings on one lot with off-street parking • 7,631 SF lot with the potential to add up to 4 ADUs Please reach out for more information about these transactions or to discuss other investment opportunities.
