What this means for you Summary
Snapshot
- This is a 3-bed/2.0-bath manufactured listed at $195k.
Deal economics
- At list price, monthly cash flow is $718 ($9k/yr) — positive.
- The deal already cash-flows at list — no discount required.
- Meets the 1% rule at list price ($3k rent vs $195k).
- Recommended offer: $172k (12.0% below list) — sets the bar for market timing.
- Cap rate 13.3% vs local median 2.7% in Bethel Island — 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 49/100 on livability (#1,166 in CA) — a working-class tenant base; expect higher turnover. Strengths: crime A-; Watch: employment C-, schools F, amenities F.
- Oakley Union Elementary (suburban): math 26% / reading 40% proficiency, ranked #837 of 1,400 in CA (top 60%) — families likely to look elsewhere, expect single-tenant / working-renter base with shorter leases.
- Market conditions: 78 active listings in the ZIP; 2,169 units permitted in Contra Costa County in 2024 (896 in 5+ unit buildings).
Forward outlook
- In year one you build about $21k of equity ($1k loan paydown + $20k appreciation (10.0% local appreciation)).
- Contra Costa County population projected at +26% by 2050 — long-run rental-demand tailwind backs the buy-and-hold thesis.
- At projected returns (10.0% appreciation + 3.0% rent growth), your $55k cash investment doubles in ~2 years — after that, you're playing with house money.
- By year 2, paydown + projected appreciation supports a ~$34k cash-out refi (75% LTV) — recoverable capital for the next deal without selling this one.
Negotiation context
- It's been on market 130 days — a 12% lower offer ($172k) is reasonable based on typical stale-listing flexibility.
- 3 sale attempts since 4y ago; this cycle's ask has dropped $15k (7%) from the opening price — seller is motivated, your offer sets the floor, not the list.
- Current owner paid $145k; 34% above their basis — modest negotiation headroom, anchor on the comps not their cost.
Risks & watch-outs
- Watch-outs: flood insurance adds $427/mo.
- Climate carrying-cost: in FEMA flood zone AE (mandatory federal flood insurance); extreme-heat days projected 7→14/yr by 2055 (HVAC capex compounding) — expect insurance premiums to compound above CPI over the hold.
Questions for the listing agent
- It's been on market 130 days. Have you received any prior offers? Is the seller open to a 12% concession, seller financing, or rate buy-down credit?
- Built in 1979 — 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 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?
- 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.

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.
