Investment Insights
Based on property information with market context.
This 2,700-square-foot duplex was built in 1921 on a 1,307-square-foot lot in San Francisco’s SOMA district. The lower residence includes 3 bedrooms, an office or bonus room, 1 bath, an open kitchen with dining area, and shared stackable laundry. Upstairs, the 2-bedroom residence has an office or bonus room, 2 baths, and dedicated laundry. Both units have updated kitchens with hardwood floors, stainless steel appliances, slab stone countertops, and custom-painted wood cabinetry. The upper unit also includes remodeled bathrooms with tile flooring and tub/shower enclosures.
An additional unwarranted 1-bedroom, 1-bath in-law unit provides further household flexibility. The property can be delivered completely vacant and includes on-street parking, forced-air heating, and public water service. Its SOMA setting places the property near Downtown San Francisco, Market Street, BART, MUNI, Mission Bay, Yerba Buena Gardens, Civic Center, major freeways, and the Gene Friend Recreation Center.

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
$95,957
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
6.86%
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.
