Investor read

• This is a 2-bed/1.0-bath manufactured listed at $100k. Condition is rated good.
• At list price, monthly cash flow is $754 ($9k/yr) — positive.
• The deal already cash-flows at list — no discount required.
• Meets the 1% rule at list price ($2k rent vs $100k).
• It's been on market 278 days — a 12% lower offer ($88k) is reasonable based on typical stale-listing flexibility.
• Recommended offer: $88k (12.0% below list) — sets the bar for market timing.
• Local home prices are declining (-3.0%/yr); year-one equity from $691 of loan paydown is wiped out by about $3k of value loss. Plan a longer hold.
• Location reads 78/100 on livability (#118 in WA, #2,417 nationally) — a middle-class / working-renter tenant base. Strengths: commute A+, housing A+, health & safety A+; Watch: schools F, crime F, cost of living F.
• Highline School District (suburban): math 36% / reading 49% proficiency, ranked #200 of 291 in WA (top 69%) — families likely to look elsewhere, expect single-tenant / working-renter base with shorter leases.
• Market conditions: Rents soft (-0.7%/yr); 99 active listings in the ZIP; 19 comparable units currently listed for rent nearby; rentals at typical pace (median 16d on market — plan ~3-4 weeks tenant-placement turnaround); solid renter incomes; 10,555 units permitted in King County in 2024 (7,119 in 5+ unit buildings).
• King County population projected at +44% by 2050 — long-run rental-demand tailwind backs the buy-and-hold thesis.
• At projected returns (-3.0% appreciation + 0.0% rent growth), your $28k cash investment doubles in ~5 years — after that, you're playing with house money.
• Cap rate 15.3% vs local median 3.0% in SeaTac — 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.

Questions for listing agent

• It's been on market 278 days. Have you received any prior offers? Is the seller open to a 12% concession, seller financing, or rate buy-down credit?
• 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 F-rated, which usually means shorter tenancies and higher turnover. Who's the typical renter profile here, and what's been the actual vacancy rate?
• 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 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.
