What this means for you Summary
Snapshot
- This is a 12 × 12-bed/12.0-bath units multifamily listed at $5.18M.
Deal economics
- At list price, monthly cash flow is $9k ($107k/yr) — positive. Per door: $742/mo.
- The deal already cash-flows at list — no discount required.
- Meets the 1% rule at list price ($52k rent vs $5.18M).
- Recommended offer: $4.56M (12.0% below list) — sets the bar for market timing.
- Cap rate 8.5% vs local median 1.2% in San Mateo — 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 79/100 on livability (#56 in CA, #2,095 nationally) — a middle-class / working-renter tenant base. Strengths: amenities A+, commute A+, employment A+; Watch: cost of living F.
- San Mateo Union High (suburban): math 50% / reading 70% proficiency, ranked #178 of 1,400 in CA (top 13%) — acceptable for families but not a draw, mixed tenant base, ~2y average lease.
- Market conditions: Rents rising fast (+4.6%/yr); 58 active listings in the ZIP; high-income renter base; 1,019 units permitted in San Mateo County in 2024 (484 in 5+ unit buildings).
- At $51,863/mo this rent would consume 509% of the median local household income ($122k/yr) (locally 2173% 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 $36k of loan paydown is wiped out by about $155k of value loss. Plan a longer hold.
- San Mateo County population projected at +24% by 2050 — long-run rental-demand tailwind backs the buy-and-hold thesis.
Negotiation context
- It's been on market 133 days — a 12% lower offer ($4.56M) is reasonable based on typical stale-listing flexibility.
- 4 sale attempts since 5y 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 $810k; list at $5.18M implies a 540% gain — meaningful room to come down on a strong offer.
Risks & watch-outs
- Watch-outs: flood insurance adds $427/mo; built in 1954 — expect roof / HVAC / electrical / plumbing capex.
- Climate carrying-cost: in FEMA flood zone AE (mandatory federal flood insurance) — expect insurance premiums to compound above CPI over the hold.
Questions for the listing agent
- It's been on market 133 days. Have you received any prior offers? Is the seller open to a 12% concession, seller financing, or rate buy-down credit?
- 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 1954 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
- What's the actual annual flood-insurance premium (NFIP or private), and is the property in a SFHA with mandatory coverage?
- Why hasn't it sold? Are there any deal-killer items the seller is aware of (foundation, flood, title, zoning, code violations)?
- 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?
- 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.
