What this means for you Summary

Snapshot

  • This is a 3-bed/2.5-bath single-family listed at $190k.

Deal economics

  • At list price, monthly cash flow is $101 ($1k/yr) — positive.
  • The deal already cash-flows at list — no discount required.
  • Meets the 1% rule at list price ($2k rent vs $190k).
  • Recommended offer: $184k (3.0% below list) — sets the bar for market timing.
  • Cap rate 6.9% vs local median 4.2% in Portland — 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 80/100 on livability (#36 in TX, #1,740 nationally) — a professional / high-income tenant draw. Strengths: employment A+, cost of living A+, housing A+; Watch: amenities F, commute F.
  • Gregory-Portland ISD (suburban): math 41% / reading 42% proficiency, ranked #314 of 826 in TX (top 38%) — families likely to look elsewhere, expect single-tenant / working-renter base with shorter leases.
  • Market conditions: Rents soft (-1.8%/yr); 302 active listings in the ZIP; 14 comparable units currently listed for rent nearby; rentals leasing fast (median 14d on market — plan ~1-2 weeks tenant-placement turnaround); solid renter incomes; 344 units permitted in San Patricio 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.
  • San Patricio County population projected at +27% by 2050 — long-run rental-demand tailwind backs the buy-and-hold thesis.

Negotiation context

  • It's been on market 56 days — a 3% lower offer ($184k) is reasonable based on typical stale-listing flexibility.

Risks & watch-outs

  • Watch-outs: property tax is 2.9% of price.
  • Climate carrying-cost: severe wind risk, 99% chance of damaging wind over 30y; extreme-heat days projected 7→27/yr by 2055 (HVAC capex compounding) — expect insurance premiums to compound above CPI over the hold.
Recommended offer $184,300 (3.0% below list)

Questions for the listing agent

  1. It's been on market 56 days. Have you received any prior offers? Is the seller open to a 3% concession, seller financing, or rate buy-down credit?
  2. Built in 1977 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
  3. Property tax is high relative to price — has the assessment been appealed recently, and will the sale trigger a re-assessment?
  4. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
  5. 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.
  6. 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.
  7. 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.
