Investor read

• This is a 3-bed/2.5-bath single-family listed at $141k. Condition is rated excellent.
• At list price, monthly cash flow is $231 ($3k/yr) — positive.
• The deal already cash-flows at list — no discount required.
• Meets the 1% rule at list price ($2k rent vs $141k).
• It's been on market 102 days — a 9% lower offer ($128k) is reasonable based on typical stale-listing flexibility.
• Recommended offer: $128k (9.0% below list) — sets the bar for market timing.
• In year one you build about $742 of equity ($975 loan paydown + $-233 appreciation (-0.2% local appreciation)).
• Location reads 80/100 on livability (#31 in TX, #1,616 nationally) — a professional / high-income tenant draw. Strengths: amenities A+, commute A+, cost of living A+; Watch: crime F.
• East Central ISD (rural): math 16% / reading 25% proficiency, ranked #758 of 826 in TX (top 92%) — low school quality limits family demand, transient renter base, plan for 1-2y turnover; 61% free/reduced lunch — lower-income household profile, screen leases tightly.
• Zoned schools: Harmony El (math 21% / reading 17%, grade F, #3,739 of 4,322 statewide, top 87%, 684 students, 75% FRL); East Central Heritage Middle (math 11% / reading 26%, grade F, #1,478 of 1,662 statewide, top 90%, 1,120 students, 44% FRL); East Central H S (math 21% / reading 28%, grade F, #1,264 of 1,632 statewide, top 82%, 3,252 students, 52% FRL) — zoned schools at 57% FRL track the district average.
• Market conditions: 449 active listings in the ZIP; 7 comparable units currently listed for rent nearby; rentals leasing fast (median 1d on market — plan ~1-2 weeks tenant-placement turnaround); 8,308 units permitted in Bexar County in 2024 (2,506 in 5+ unit buildings).
• Bexar County population projected at +50% by 2050 — long-run rental-demand tailwind backs the buy-and-hold thesis.
• At projected returns (-0.2% appreciation + 3.0% rent growth), your $39k cash investment doubles in ~8 years — after that, you're playing with house money.
• Cap rate 8.3% vs local median 3.8% in San Antonio — 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.

Questions for listing agent

• It's been on market 102 days. Have you received any prior offers? Is the seller open to a 9% concession, seller financing, or rate buy-down credit?
• What does the HOA fee cover, when was the last increase, and are there any pending special assessments or reserve-fund shortfalls?
• 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.
• 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.
• 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.
• 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.
