🏷️ Possibly a rental listed for sale. The $1,195,000 price doesn't fit this home's estimated sale value (~$1,761,462) and the remarks read like a rental — treat the cards below with caution.

What this means for you Summary

Snapshot

  • This is a 3-bed/2.0-bath single-family listed at $1.20M.

Deal economics

  • At list price, monthly cash flow is $-727 ($-9k/yr) — negative.
  • To cash-flow at today's rent, offer at most $1.07M (10.7% below list).
  • To meet the 1% rule (rent ≥ 1% of price), the offer needs to be $866k (27.5% below list).
  • Recommended offer: $866k (27.5% below list) — sets the bar for 1% rule.
  • Cap rate 5.6% 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 (+9.7%/yr); 65 active listings in the ZIP; 11 comparable units currently listed for rent nearby; rentals at typical pace (median 26d on market — plan ~3-4 weeks tenant-placement turnaround); high-income renter base; 750 units permitted in San Francisco County in 2024 (688 in 5+ unit buildings).
  • At $8,661/mo this rent would consume 71% of the median local household income ($146k/yr) (locally 2227% 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 $8k of loan paydown is wiped out by about $36k 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.

Negotiation context

  • It's been on market 34 days — a 3% lower offer ($1.16M) is reasonable based on typical stale-listing flexibility.
  • 7 sale attempts since 30y ago with the ask held roughly flat each time — persistent listings suggest the price (not the market) is what's stuck; bring a comps-based counter.
  • Current owner paid $607k; list at $1.20M implies a 97% gain — meaningful room to come down on a strong offer.

Risks & watch-outs

  • Watch-outs: built in 1911 — expect roof / HVAC / electrical / plumbing capex.
Recommended offer $866,074 (27.5% below list)

Questions for the listing agent

  1. What do current leases actually rent for vs. the listed asking? Can we see a recent rent roll and the last 12 months of T-12 income?
  2. It's been on market 34 days. Have you received any prior offers? Is the seller open to a 28% concession, seller financing, or rate buy-down credit?
  3. Built in 1911 — 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. The area grade is low — what's the realistic commute time and amenity access for the typical tenant pool here? Any planned neighborhood developments (good or bad) we should know about?
  8. 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.
  9. 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.
  10. How much new for-sale + rental construction is in the pipeline within 1–3 miles? Heavy new supply typically softens prices + rents 12–24 months out; constrained supply supports both.

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.
