Listing remarks

This is a great location just a few doors walking distance to one of the swimming pools. This is a family park and all families are owners in the community. There are no renters. That's one reason this community is so clean. Come and see for yourself. This is a great retirement home or maybe even a just getting started home. This home won't last long so come and see if it's the right place for you. Call your agent to show it to you today. Open 6/14/26

What this means for you Summary

Snapshot

• This is a 2-bed/1.5-bath manufactured listed at $125k. Condition is rated good.

Deal economics

• At list price, monthly cash flow is $884 ($11k/yr) — positive.
• The deal already cash-flows at list — no discount required.
• Meets the 1% rule at list price ($2k rent vs $125k).
• Cap rate 14.8% vs local median 2.8% in Concord — 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 65/100 on livability (#397 in CA) — a middle-class / working-renter tenant base. Strengths: employment A+, health & safety A+, housing B; Watch: schools C-, crime F, amenities F.
• Mt. Diablo Unified (suburban): math 36% / reading 45% proficiency, ranked #202 of 517 in CA (top 39%) — families likely to look elsewhere, expect single-tenant / working-renter base with shorter leases.
• Market conditions: Rents rising (+2.8%/yr); 128 active listings in the ZIP; 40 comparable units currently listed for rent nearby; rentals at typical pace (median 19d on market — plan ~3-4 weeks tenant-placement turnaround); high-income renter base; 2,169 units permitted in Contra Costa County in 2024 (896 in 5+ unit buildings).

Forward outlook

• Local home prices are declining (-3.0%/yr); year-one equity from $864 of loan paydown is wiped out by about $4k of value loss. Plan a longer hold.
• Contra Costa County population projected at +26% by 2050 — long-run rental-demand tailwind backs the buy-and-hold thesis.
• At projected returns (-3.0% appreciation + 2.8% rent growth), your $35k cash investment doubles in ~4 years — after that, you're playing with house money.

Negotiation context

• Only 6 days on market — expect competitive offers; lowballing is unlikely to land.

Recommended offer $125,000

Questions for the listing agent

1. Built in 1971 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
2. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
3. 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?
4. 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.
5. 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.
6. 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.
