Both of the 3bd/2ba units feature a gas fireplace, spacious rooms, and great natural light. One of these units will be delivered vacant, providing a great owner's unit or the ability to achieve market rent. The units are separately metered for gas and electricity, and each has their own furnace, keeping operating expenses low. The main electrical indicates 400 Amps of service and all of the subpanels in the apartments were recently replaced. This is an excellent opportunity to acquire a turn-key building with gr

What this means for you Summary
Snapshot
- This is a 2×3bd/2ba + 2×2bd/1.5ba + 2×1bd/1ba units multifamily listed at $2.80M.
Deal economics
- At list price, monthly cash flow is $4k ($44k/yr) — positive. Per door: $617/mo.
- The deal already cash-flows at list — no discount required.
- To meet the 1% rule (rent ≥ 1% of price), the offer needs to be $2.58M (8.0% below list).
- Recommended offer: $2.58M (8.0% below list) — sets the bar for 1% rule.
- Cap rate 7.9% vs local median 2.1% in San Francisco — top-decile yield for the area; either an underpriced asset or a hidden risk that comps aren't pricing in. Stress-test before assuming the spread holds.
Location & tenants
- Location reads 76/100 on livability (#90 in CA, #3,143 nationally) — a middle-class / working-renter tenant base. Strengths: amenities A+, commute A+, employment A+; Watch: crime F, cost of living F.
- San Francisco Unified (urban): math 50% / reading 56% proficiency, ranked #322 of 1,400 in CA (top 23%) — acceptable for families but not a draw, mixed tenant base, ~2y average lease.
- Zoned schools: Lilienthal (Claire) Elementary (669 students, 19% FRL); Giannini (A.P.) Middle (1,192 students, 34% FRL); Lowell High (2,632 students, 37% FRL) — zoned schools average 30% FRL vs 49% district-wide (19 pts lower); this property's tenant base skews higher-income than the district average.
- Market conditions: Rents rising fast (+13.0%/yr); 76 active listings in the ZIP; high-income renter base; 750 units permitted in San Francisco County in 2024 (688 in 5+ unit buildings).
- At $25,769/mo this rent would consume 232% of the median local household income ($133k/yr) (locally 2072% of renters already pay >50% of income on rent) — very limited rent-growth headroom before tenants either downsize or default.
Forward outlook
- Local home prices are declining (-3.0%/yr); year-one equity from $19k of loan paydown is wiped out by about $84k of value loss. Plan a longer hold.
- San Francisco County population projected at +39% by 2050 — long-run rental-demand tailwind backs the buy-and-hold thesis.
- At projected returns (-3.0% appreciation + 8.0% rent growth), your $784k cash investment doubles in ~9 years — after that, you're playing with house money.
Negotiation context
- It's been on market 17 days — a 2% lower offer ($2.76M) is reasonable based on typical stale-listing flexibility.
Questions for the listing agent
- Can we see the unit-by-unit rent roll, current vacancy, and any below-market leases? What's the average tenancy length?
- What capital expenditures (roof, boiler, parking lot, exteriors) have been made in the last 5 years, and what's planned in the next 2?
- Built in 1972 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
- Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
- Schools are B-rated — typically a magnet for longer-tenancy family renters. What's the average tenant stay here, and is there a school-zone premium baked into asking?
- Crime grade is F in this area — have there been break-ins, vandalism, or insurance claims at this property in the last 3 years? What carrier currently insures it and at what premium?
- What's the average days-on-market for RENTAL listings here right now (not sales)? A rising rental-DOM trend means longer vacancies and softer asking-rent achievability than the comps imply.
- What's the recent tenant-quality profile in this submarket — average credit score on applications, eviction rate, late-payment / NSF rate, and stable-employment percentage? A property-management company in the area should have these aggregated.
- How much new apartment / multifamily construction is in the pipeline within 1–3 miles? Heavy new supply (>2% of stock underway) typically softens rents 12–24 months out; light construction supports rent growth.

For passive investors: Depreciation is non-cash, so a rental often shows a tax loss while cash-flowing — sheltering income. Rental losses are passive: they offset passive income freely, and up to $25,000/yr can offset ordinary (W-2) income if you actively participate and your MAGI is under $100k (phasing out to $0 by $150k); unused losses carry forward. On sale, claimed depreciation is recaptured at up to 25%, and gains may owe capital-gains tax (a 1031 exchange can defer both). Figures are a year-1 estimate at your 24.0% rate — not tax advice; consult a CPA.
