What this means for you Summary

Snapshot

  • This is a 3 × 3-bed/4.0-bath units multifamily listed at $1.29M.

Deal economics

  • At list price, monthly cash flow is $4k ($54k/yr) — positive. Per door: $1k/mo.
  • The deal already cash-flows at list — no discount required.
  • Meets the 1% rule at list price ($17k rent vs $1.29M).
  • Cap rate 10.5% 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.
  • Market conditions: Rents rising fast (+14.4%/yr); 116 active listings in the ZIP; high-income renter base; 750 units permitted in San Francisco County in 2024 (688 in 5+ unit buildings).
  • At $16,945/mo this rent would consume 100% of the median local household income ($204k/yr) (locally 1336% of renters already pay >50% of income on rent) — very limited rent-growth headroom before tenants either downsize or default.

Forward outlook

  • In year one you build about $131k of equity ($9k loan paydown + $122k appreciation (9.5% local appreciation)).
  • San Francisco County population projected at +39% by 2050 — long-run rental-demand tailwind backs the buy-and-hold thesis.
  • At projected returns (9.5% appreciation + 8.0% rent growth), your $361k cash investment doubles in ~2 years — after that, you're playing with house money.
  • By year 2, paydown + projected appreciation supports a ~$211k cash-out refi (75% LTV) — recoverable capital for the next deal without selling this one.

Negotiation context

  • Only 14 days on market — expect competitive offers; lowballing is unlikely to land.

Risks & watch-outs

  • Watch-outs: built in 1900 — expect roof / HVAC / electrical / plumbing capex.
Recommended offer $1,288,000

Questions for the listing agent

  1. Can we see the unit-by-unit rent roll, current vacancy, and any below-market leases? What's the average tenancy length?
  2. What capital expenditures (roof, boiler, parking lot, exteriors) have been made in the last 5 years, and what's planned in the next 2?
  3. Built in 1900 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
  4. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
  5. 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?
  6. 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?
  7. 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.
  8. 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.
  9. 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.
