Key facts
- Listed 16 days
Neighborhood map
What this means for you Summary
Snapshot
- This is a 1-bed/1.0-bath manufactured listed at $74k.
Deal economics
- At list price, monthly cash flow is $1k ($14k/yr) — positive.
- The deal already cash-flows at list — no discount required.
- Meets the 1% rule at list price ($2k rent vs $74k).
- Recommended offer: $73k (1.5% below list) — sets the bar for market timing.
- Cap rate 25.3% vs local median 1.8% in Castro Valley — 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 74/100 on livability (#129 in CA, #4,461 nationally) — a middle-class / working-renter tenant base. Strengths: commute A+, employment A+, schools A; Watch: amenities F, cost of living F.
- Castro Valley Unified (suburban): math 60% / reading 69% proficiency, ranked #60 of 517 in CA (top 12%) — acceptable for families but not a draw, mixed tenant base, ~2y average lease; only 16% free/reduced lunch — higher-income household profile.
- Market conditions: Rents rising (+3.4%/yr); 108 active listings in the ZIP; 24 comparable units currently listed for rent nearby; rentals at typical pace (median 15d on market — plan ~3-4 weeks tenant-placement turnaround); high-income renter base; 1,742 units permitted in Alameda County in 2024 (856 in 5+ unit buildings).
Forward outlook
- Local home prices are declining (-3.0%/yr); year-one equity from $515 of loan paydown is wiped out by about $2k of value loss. Plan a longer hold.
- Alameda County population projected at +34% by 2050 — long-run rental-demand tailwind backs the buy-and-hold thesis.
- At projected returns (-3.0% appreciation + 3.4% rent growth), your $21k cash investment doubles in ~2 years — after that, you're playing with house money.
Negotiation context
- It's been on market 16 days — a 2% lower offer ($73k) is reasonable based on typical stale-listing flexibility.
- 2 sale attempts since 23y 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 $30k; list at $74k implies a 148% gain — meaningful room to come down on a strong offer.
Questions for the listing agent
- Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
- 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?
- 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.
