Overview

Active

Listed Sep 23, 2025

Updated Apr 10

Rare single story triplex consisting of a stand alone cottage and a duplex building on a large 7,631 SqFt lot in one of the Bay Area's most coveted submarkets. Located in close proximity to Downtown Burlingame, Downtown San Mateo, SFO and other landmarks. An ADU consultancy's pre-feasibility study indicates that up to four Accessory Dwelling Units can be added which would drive substantial income and appreciation. Up to 75% LTV conventional financing. Opportunity for future owner-occupancy and a low cost alternative to a single family home. Two one-bedroom/one-bathroom units and one two-bedroom/one-bathroom unit. All three units are large and have private yards and are occupied, providing steady rental income. Tremendous rental income upside upon unit turnover and renovation. There is a three vehicle car-port in the back of the property. Monthly rent: $7,300 (current), $10,000 (proforma). The strong rent growth, shortage of housing units, proximity to large Silicon Valley employers, and ADU potential make 321 Grand Boulevard an exceptional investment for both the cash flow and appreciation-minded investor. Offering memorandum, disclosures, and walkthrough video available.
