What this means for you Summary

Snapshot

  • This is a 4 × 1-bed/1-bath units multifamily listed at $900k.

Deal economics

  • At list price, monthly cash flow is $-376 ($-5k/yr) — negative. Per door: $-94/mo.
  • To cash-flow at today's rent, offer at most $834k (7.4% below list).
  • To meet the 1% rule (rent ≥ 1% of price), the offer needs to be $673k (25.2% below list).
  • Recommended offer: $673k (25.2% below list) — sets the bar for 1% rule.
  • Cap rate 5.8% vs local median 1.6% in Seattle — 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 75/100 on livability (#166 in WA, #4,033 nationally) — a middle-class / working-renter tenant base. Strengths: amenities A+, commute A+, employment A+; Watch: crime F, cost of living F.
  • Seattle Public Schools (urban): math 64% / reading 72% proficiency, ranked #19 of 291 in WA (top 6%) — acceptable for families but not a draw, mixed tenant base, ~2y average lease.
  • Zoned schools: Concord International School (306 students, 71% FRL); Cleveland High School Stem (902 students, 57% FRL) — zoned schools average 64% FRL vs 30% district-wide (33 pts higher); higher-poverty schools than district average — tighter screening recommended.
  • Market conditions: Rents flat; 135 active listings in the ZIP; solid renter incomes; 10,555 units permitted in King County in 2024 (7,119 in 5+ unit buildings).
  • At $6,734/mo this rent would consume 84% of the median local household income ($96k/yr) (locally 813% 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 $6k of loan paydown is wiped out by about $27k of value loss. Plan a longer hold.
  • King County population projected at +44% by 2050 — long-run rental-demand tailwind backs the buy-and-hold thesis.

Negotiation context

  • It's been on market 37 days — a 3% lower offer ($873k) is reasonable based on typical stale-listing flexibility.
  • 3 sale attempts since 21y 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 $225k; list at $900k implies a 300% gain — meaningful room to come down on a strong offer.

Risks & watch-outs

  • Watch-outs: built in 1901 — expect roof / HVAC / electrical / plumbing capex.
  • Climate carrying-cost: moderate flood risk — expect insurance premiums to compound above CPI over the hold.
Recommended offer $673,400 (25.2% 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 37 days. Have you received any prior offers? Is the seller open to a 25% concession, seller financing, or rate buy-down credit?
  3. Can we see the unit-by-unit rent roll, current vacancy, and any below-market leases? What's the average tenancy length?
  4. What capital expenditures (roof, boiler, parking lot, exteriors) have been made in the last 5 years, and what's planned in the next 2?
  5. Built in 1901 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
  6. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
  7. Schools are A-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?
  8. 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?
  9. 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?
  10. 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.
  11. 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.
  12. 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.
