About this home

We found 3 Cons,5 Pros. Rank: price - $1.89M(50th), sqft - 2410(33th), beds - undefined(50th), baths - undefined(50th).

Rare turnkey tutor style fourplex situated on a large 7,591 SqFt lot in one of the Bay Area's most coveted submarkets. Opportunity for owner-occupancy with up to 80% LTV conventional financing. Low cost alternative to a single family home. Three studio units and one 2-bed/1-bath unit. Two vacant fully remodeled units - a rear cottage studio and a 2-Bed/1-Bath flat - both with in-unit laundry. Substantial capital improvements completed including new electrical wiring and sub-panels, copper plumbing throughout, roof (2017), fencing, asphalt and concrete, and three units completely remodeled with high-end finishes. Two studios are rented, one of which is fully remodeled. An ADU consultancy's pre-feasibility study indicates that up to 5 ADU units can be added which would drive substantial income and appreciation. There are 2 private 1-car garages and 5 uncovered parking spaces. Monthly rent: $9,965 (scheduled), $10,885 (proforma). The strong rent growth, shortage of housing units, proximity to large Silicon Valley employers, and ADU potential make 315 Grand Boulevard an exceptional investment for both the cash flow and appreciation-minded investor. The adjacent triplexes at 321 Grand Blvd and 327 Grand Blvd are also available for sale.

Despite being built in 1927, this property has undergone extensive and recent renovations. The listing explicitly states 'new electrical wiring and sub-panels, copper plumbing throughout, roof (2017),' and 'three units completely remodeled with high-end finishes.' The images confirm modern, high-quality kitchens with new cabinets, quartz countertops, stainless steel appliances (mostly), recessed lighting, and updated flooring. Bathrooms are also modern and clean. The major system upgrades and the comprehensive remodeling of 75% of the units bring the property's condition to a virtually new standard, making it move-in ready with no deferred maintenance in the renovated areas.
Pros & Cons

Pros

Significant ADU Potential: A pre-feasibility study indicates the potential to add up to 5 Accessory Dwelling Units (ADUs), offering substantial future income growth and property appreciation.
Extensive Capital Improvements: The property has undergone substantial recent upgrades, including new electrical wiring, copper plumbing, a 2017 roof, fencing, asphalt, concrete, and three fully remodeled units with high-end finishes, reducing immediate capital expenditure for a new owner.
Prime Bay Area Location: Located in a highly coveted San Mateo submarket, benefiting from strong rent growth, a housing shortage, and close proximity to major Silicon Valley employers, ensuring high demand.
Turnkey & Owner-Occupancy Opportunity: Two fully remodeled units (a 2-bed/1-bath and a studio) are vacant, allowing for immediate owner-occupancy or market-rate rental, supported by attractive 80% LTV conventional financing options.
Ample Parking & Large Lot: The property includes 2 private 1-car garages and 5 uncovered parking spaces, along with a generous 7,591 SqFt lot, providing convenience for tenants and potential for further development.

Cons

Age of Property: Built in 1927, the property's age, despite recent renovations, may lead to unforeseen maintenance challenges or higher insurance costs associated with older structures.
Recent Price Reduction: A recent price drop from $1.95M to $1.888M could suggest initial overpricing or slower market interest, potentially impacting buyer perception or negotiation leverage.
Capital & Execution Required for ADU Potential: While offering significant upside, realizing the full ADU potential requires substantial additional capital investment, navigating complex permitting, and managing construction, introducing execution risk and delaying full value realization.
