Investor read

• This is a 3-bed/1.0-bath single-family listed at $156k.
• At list price, monthly cash flow is $42 ($499/yr) — positive.
• The deal already cash-flows at list — no discount required.
• Meets the 1% rule at list price ($2k rent vs $156k).
• It's been on market 598 days — a 12% lower offer ($137k) is reasonable based on typical stale-listing flexibility.
• Recommended offer: $137k (12.0% below list) — sets the bar for market timing.
• Local home prices are declining (-3.0%/yr); year-one equity from $1k of loan paydown is wiped out by about $5k of value loss. Plan a longer hold.
• Location reads 74/100 on livability (#184 in TX, #4,771 nationally) — a middle-class / working-renter tenant base. Strengths: amenities A+, cost of living A+, housing A+; Watch: schools D, crime F.
• Houston ISD (urban): math 27% / reading 35% proficiency, ranked #593 of 826 in TX (top 72%) — families likely to look elsewhere, expect single-tenant / working-renter base with shorter leases; 71% free/reduced lunch — lower-income household profile, screen leases tightly.
• Watch-outs: flood insurance adds $66/mo; built in 1940 — expect roof / HVAC / electrical / plumbing capex.
• Market conditions: Rents rising (+2.2%/yr); 467 active listings in the ZIP; 39 comparable units currently listed for rent nearby; rentals at typical pace (median 22d on market — plan ~3-4 weeks tenant-placement turnaround); 29,883 units permitted in Harris County in 2024 (8,621 in 5+ unit buildings).
• Harris County population projected at +47% by 2050 — long-run rental-demand tailwind backs the buy-and-hold thesis.
• Climate carrying-cost: major flood risk; severe wind risk, 99% chance of damaging wind over 30y; extreme-heat days projected 7→24/yr by 2055 (HVAC capex compounding) — expect insurance premiums to compound above CPI over the hold.
• Cap rate 7.1% vs local median 3.2% in Houston — 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.
• This rent runs 41% of the median local income ($46k/yr) — at the standard rent-burdened threshold; future hikes will face affordability resistance.

Questions for listing agent

• It's been on market 598 days. Have you received any prior offers? Is the seller open to a 12% concession, seller financing, or rate buy-down credit?
• Built in 1940 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
• What's the actual annual flood-insurance premium (NFIP or private), and is the property in a SFHA with mandatory coverage?
• Why hasn't it sold? Are there any deal-killer items the seller is aware of (foundation, flood, title, zoning, code violations)?
• Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
• 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?
• 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?
• 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.
