What this means for you Summary

Snapshot

• This is a 3-bed/1.0-bath single-family listed at $185k.

Deal economics

• At list price, monthly cash flow is $643 ($8k/yr) — positive.
• The deal already cash-flows at list — no discount required.
• Meets the 1% rule at list price ($2k rent vs $185k).
• Cap rate 10.5% vs local median 2.0% in Copperopolis — 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 58/100 on livability (#691 in CA) — a working-class tenant base; expect higher turnover. Strengths: housing A+, employment A-, crime B+; Watch: schools D+, amenities F, commute F.
• Bret Harte Union High (town): math 35% / reading 65% proficiency, ranked #429 of 1,400 in CA (top 31%) — acceptable for families but not a draw, mixed tenant base, ~2y average lease.
• Market conditions: 235 active listings in the ZIP; 77 units permitted in Calaveras County in 2024 (0 in 5+ unit buildings).

Forward outlook

• Local home prices are declining (-3.0%/yr); year-one equity from $1k of loan paydown is wiped out by about $6k of value loss. Plan a longer hold.
• Calaveras County population projected at -18% by 2050 — secular population decline; favor cash flow + early exit over multi-decade hold.
• At projected returns (-3.0% appreciation + 3.0% rent growth), your $52k cash investment doubles in ~8 years — after that, you're playing with house money.

Negotiation context

• Only 3 days on market — expect competitive offers; lowballing is unlikely to land.

Risks & watch-outs

• Watch-outs: built in 1938 — expect roof / HVAC / electrical / plumbing capex.
• Climate carrying-cost: major wildfire risk; extreme-heat days projected 7→17/yr by 2055 (HVAC capex compounding) — expect insurance premiums to compound above CPI over the hold.

Recommended offer $185,000

Questions for the listing agent

1. Built in 1938 — 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. Schools are D-rated, which usually means shorter tenancies and higher turnover. Who's the typical renter profile here, and what's been the actual vacancy rate?
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.
