Investment Insights
Based on property information with market context.
This vacant two-unit office property occupies a 3,772-square-foot lot and was built in 1912. The upper suite spans the second and third floors, while the first-floor suite includes a Union Street-facing front room, private rooms, kitchen, full bath, and rear access. Across the building, features include hardwood floors, period millwork, fireplaces, substantial windows, skylights, and high ceilings. A basement adds storage, built-in shelving, utility areas, wet-bar areas, a bathroom, and a tradesman entrance. The property is heated by central and radiant systems and has wood siding with shingle and composition roofing.
The building was converted to F-2 Business/Office use in 1976, according to the Certificate of Final Completion and Occupancy. Its location on Union Street places it among restaurants, cafes, boutiques, wellness businesses, and professional services, with the Marina, Pacific Heights, and Fort Mason nearby. A landscaped rear yard and roof-level viewing platform provide additional outdoor features, with outlooks toward the Bay, Marina, Marin Headlands, and Golden Gate Bridge.

Financial Insights
Estimated NOI and Cap Rate
NOI = area × lease_rate × (100 − vacancy) / 100 × (1 − expense_ratio). Net Operating Income — what the owner takes home each year before mortgage payments and income tax. Effective rent (asking rent minus vacancy losses) minus operating costs (taxes, insurance, maintenance, management).
NOI / Yr
$110,241
Cap rate = NOI / list price × 100. Capitalization rate — annual return on a fully cash purchase, before financing. NOI divided by price. Higher means more income per dollar invested, but usually also more risk or older condition. 5–8% is typical for stabilized commercial property; double digits often signal distressed deals.
Cap Rate
5.82%
Suggested Prices Based on Cap Rates
Cap rates vary significantly by property type, market, and asset quality.
Typical U.S. stable-market ranges:
Multifamily — 4.5% to 6.5% (Class A in primary markets often sub-5%; Class C in secondary markets 6%+)
Industrial / Logistics — 5.0% to 7.0% (compressed heavily in recent years due to e-commerce demand)
Office — 6.5% to 9%+ (wide spread post-2020; CBD Class A vs. suburban Class B varies dramatically)
Retail — 5.5% to 8.5% (grocery-anchored on the low end, unanchored strip centers higher)
Hospitality / Hotels — 7.5% to 10%+ (higher due to operational risk)
Self-Storage — 5.5% to 7.5%
Medical Office — 6.0% to 7.5%
Net Lease (single tenant, credit) — 5.0% to 7.0% depending on tenant credit and lease term
Rules of thumb:
Primary markets (NYC, SF, LA, Boston, DC) trade at lower cap rates than secondary/tertiary markets, often by 100–200 bps (bps, aka basis points; 1 bp = 0.01%).
Class A assets trade ~50–150 bps tighter than Class B, and Class B tighter than Class C.
Cap rates move inversely with price — a lower cap rate means a higher price for the same NOI.
Spread to the 10-year Treasury is a common benchmark; historically 200–400 bps over the 10-year.
