What this means for you Summary

Snapshot

  • This is a 2-bed/2.0-bath single-family listed at $225k.

Deal economics

  • At list price, monthly cash flow is $-314 ($-4k/yr) — negative.
  • To cash-flow at today's rent, offer at most $170k (24.6% below list).
  • Meets the 1% rule at list price ($3k rent vs $225k).
  • Recommended offer: $170k (24.6% below list) — sets the bar for cash-flow.
  • Cap rate 6.9% vs local median 3.4% in Port Isabel — 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 75/100 on livability (#157 in TX, #4,282 nationally) — a middle-class / working-renter tenant base. Strengths: cost of living A+, housing A+, health & safety A+; Watch: employment D, crime F, commute F.
  • Point Isabel ISD (town): math 14% / reading 31% proficiency, ranked #756 of 826 in TX (top 92%) — low school quality limits family demand, transient renter base, plan for 1-2y turnover.
  • Zoned schools: Port Isabel J H (math 10% / reading 29%, grade F, #1,445 of 1,662 statewide, top 88%, 425 students, 84% FRL) — zoned schools average 84% FRL vs 35% district-wide (49 pts higher); higher-poverty schools than district average — tighter screening recommended.
  • Market conditions: 261 active listings in the ZIP; 9 comparable units currently listed for rent nearby; rentals at typical pace (median 23d on market — plan ~3-4 weeks tenant-placement turnaround); 44% of comp listings sitting > 30 days — soft ceiling on asking rent; 2,326 units permitted in Cameron County in 2024 (503 in 5+ unit buildings).

Forward outlook

  • Local home prices are declining (-3.0%/yr); year-one equity from $2k of loan paydown is wiped out by about $7k 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.

Negotiation context

  • It's been on market 462 days — a 12% lower offer ($198k) is reasonable based on typical stale-listing flexibility.
  • 2 sale attempts since 2y 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.

Risks & watch-outs

  • Watch-outs: flood insurance adds $427/mo.
  • Climate carrying-cost: in FEMA flood zone AE (mandatory federal flood insurance); severe wind risk, 99% chance of damaging wind over 30y; extreme-heat days projected 6→22/yr by 2055 (HVAC capex compounding) — expect insurance premiums to compound above CPI over the hold.
Recommended offer $169,607 (24.6% below list)

Questions for the listing agent

  1. What do current leases actually rent for vs. the listed asking? Can we see a recent rent roll and the last 12 months of T-12 income?
  2. It's been on market 462 days. Have you received any prior offers? Is the seller open to a 25% concession, seller financing, or rate buy-down credit?
  3. What's the actual annual flood-insurance premium (NFIP or private), and is the property in a SFHA with mandatory coverage?
  4. What does the HOA fee cover, when was the last increase, and are there any pending special assessments or reserve-fund shortfalls?
  5. Why hasn't it sold? Are there any deal-killer items the seller is aware of (foundation, flood, title, zoning, code violations)?
  6. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
  7. 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?
  8. 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?
  9. 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.
  10. 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.
  11. 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.
