Investor read

• This is a 3-bed/1.0-bath single-family listed at $75k.
• At list price, monthly cash flow is $377 ($5k/yr) — positive.
• The deal already cash-flows at list — no discount required.
• Meets the 1% rule at list price ($1k rent vs $75k).
• It's been on market 45 days — a 3% lower offer ($73k) is reasonable based on typical stale-listing flexibility.
• Recommended offer: $73k (3.0% below list) — sets the bar for market timing.
• Local home prices are declining (-3.0%/yr); year-one equity from $519 of loan paydown is wiped out by about $2k of value loss. Plan a longer hold.
• Location reads 56/100 on livability (#1,320 in TX) — a working-class tenant base; expect higher turnover. Strengths: cost of living A+, housing A+, crime B; Watch: amenities F, commute F, employment F.
• Donna ISD (suburban): math 11% / reading 18% proficiency, ranked #821 of 826 in TX (top 99%) — low school quality limits family demand, transient renter base, plan for 1-2y turnover.
• Zoned schools: M Rivas Pri Discovery Academy (math 12% / reading 17%, grade F, #4,048 of 4,322 statewide, top 95%, 349 students, 93% FRL); A P Solis Middle (math 8% / reading 19%, grade F, #1,602 of 1,662 statewide, top 97%, 666 students, 93% FRL); Donna H S (math 16% / reading 21%, grade F, #1,436 of 1,632 statewide, top 88%, 2,095 students, 92% FRL) — zoned schools average 93% FRL vs 48% district-wide (44 pts higher); higher-poverty schools than district average — tighter screening recommended.
• Watch-outs: property tax is 2.7% of price.
• Market conditions: 349 active listings in the ZIP; 7,378 units permitted in Hidalgo County in 2024 (641 in 5+ unit buildings).
• Hidalgo County population projected at +28% by 2050 — long-run rental-demand tailwind backs the buy-and-hold thesis.
• At projected returns (-3.0% appreciation + 3.0% rent growth), your $21k cash investment doubles in ~6 years — after that, you're playing with house money.
• Climate carrying-cost: severe wind risk, 99% chance of damaging wind over 30y; severe wildfire risk; extreme-heat days projected 7→23/yr by 2055 (HVAC capex compounding) — expect insurance premiums to compound above CPI over the hold.

Questions for listing agent

• It's been on market 45 days. Have you received any prior offers? Is the seller open to a 3% concession, seller financing, or rate buy-down credit?
• Property tax is high relative to price — has the assessment been appealed recently, and will the sale trigger a re-assessment?
• Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
• 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?
• 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.
