What this means for you Summary

Snapshot

• This is a 2-bed/1.0-bath manufactured listed at $100k. Condition is rated excellent.

Deal economics

• At list price, monthly cash flow is $765 ($9k/yr) — positive.
• The deal already cash-flows at list — no discount required.
• Meets the 1% rule at list price ($2k rent vs $100k).
• Recommended offer: $88k (12.0% below list) — sets the bar for market timing.
• Cap rate 15.5% vs local median 3.1% 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.

Location & tenants

• 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); 96 active listings in the ZIP; 20 comparable units currently listed for rent nearby; rentals at typical pace (median 15d 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).

Forward outlook

• 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.
• 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 ~4 years — after that, you're playing with house money.

Negotiation context

• It's been on market 275 days — a 12% lower offer ($88k) is reasonable based on typical stale-listing flexibility.

Recommended offer $87,912 (12.0% below list)

Questions for the listing agent

1. It's been on market 275 days. Have you received any prior offers? Is the seller open to a 12% concession, seller financing, or rate buy-down credit?
2. Why hasn't it sold? Are there any deal-killer items the seller is aware of (foundation, flood, title, zoning, code violations)?
3. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
4. 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?
5. 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?
6. 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.
7. 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.
8. 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.
