What this means for you Summary

Snapshot

• This is a 1-bed/1.0-bath manufactured listed at $50k. Condition is rated good.

Deal economics

• At list price, monthly cash flow is $352 ($4k/yr) — positive.
• The deal already cash-flows at list — no discount required.
• Meets the 1% rule at list price ($878 rent vs $50k).
• Recommended offer: $44k (12.0% below list) — sets the bar for market timing.
• Cap rate 14.8% vs local median 4.1% in Harlingen — 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 73/100 on livability (#217 in TX) — a middle-class / working-renter tenant base. Strengths: amenities A+, cost of living A+, housing A+; Watch: crime C-, commute F, employment F.
• Harlingen CISD (urban): math 25% / reading 35% proficiency, ranked #647 of 826 in TX (top 78%) — families likely to look elsewhere, expect single-tenant / working-renter base with shorter leases; 74% free/reduced lunch — lower-income household profile, screen leases tightly.
• Zoned schools: Stuart Place El (math 30% / reading 40%, grade F, #1,965 of 4,322 statewide, top 46%, 613 students, 59% FRL); Moises Vela Middle (math 27% / reading 30%, grade F, #1,122 of 1,662 statewide, top 69%, 742 students, 67% FRL); Harlingen H S - South (math 47% / reading 17%, grade F, #1,044 of 1,632 statewide, top 66%, 1,571 students, 75% FRL).
• Market conditions: Rents soft (-1.9%/yr); 843 active listings in the ZIP; 2,326 units permitted in Cameron County in 2024 (503 in 5+ unit buildings).
• This rent is only 15% of the median local income ($70k/yr) — well below the 30% rent-burden line; pricing power to push rent on renewal without tenant pushback.

Forward outlook

• Local home prices are declining (-3.0%/yr); year-one equity from $342 of loan paydown is wiped out by about $1k of value loss. Plan a longer hold.
• Cameron County population projected at +3% by 2050 — modest demand growth; plan on rents tracking national, not racing it.
• At projected returns (-3.0% appreciation + 0.0% rent growth), your $14k cash investment doubles in ~5 years — after that, you're playing with house money.

Negotiation context

• It's been on market 360 days — a 12% lower offer ($44k) is reasonable based on typical stale-listing flexibility.

Risks & watch-outs

• Climate carrying-cost: severe wind risk, 99% chance of damaging wind over 30y; moderate wildfire risk; extreme-heat days projected 7→24/yr by 2055 (HVAC capex compounding) — expect insurance premiums to compound above CPI over the hold.

Recommended offer $43,560 (12.0% below list)

Questions for the listing agent

1. It's been on market 360 days. Have you received any prior offers? Is the seller open to a 12% concession, seller financing, or rate buy-down credit?
2. Built in 1978 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
3. Why hasn't it sold? Are there any deal-killer items the seller is aware of (foundation, flood, title, zoning, code violations)?
4. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
5. 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?
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.
