Investor read

• This is a 4-bed/3.0-bath single-family listed at $289k. Condition is rated good.
• At list price, monthly cash flow is $-415 ($-5k/yr) — negative.
• To cash-flow at today's rent, offer at most $236k (18.4% below list).
• To meet the 1% rule (rent ≥ 1% of price), the offer needs to be $223k (22.7% below list).
• It's been on market 86 days — a 6% lower offer ($272k) is reasonable based on typical stale-listing flexibility.
• Recommended offer: $223k (22.7% below list) — sets the bar for 1% rule.
• Local home prices are declining (-3.0%/yr); year-one equity from $2k of loan paydown is wiped out by about $9k of value loss. Plan a longer hold.
• Location reads 75/100 on livability (#155 in TX, #4,239 nationally) — a middle-class / working-renter tenant base. Strengths: cost of living A+, housing A+, health & safety B+; Watch: amenities F, commute F.
• Waller ISD (rural): math 30% / reading 35% proficiency, ranked #532 of 826 in TX (top 64%) — families likely to look elsewhere, expect single-tenant / working-renter base with shorter leases.
• Zoned schools: Evelyn Turlington El (math 46% / reading 45%, grade D-, #1,112 of 4,322 statewide, top 26%, 1,084 students, 69% FRL); Schultz J H (math 31% / reading 37%, grade F, #892 of 1,662 statewide, top 55%, 1,120 students, 65% FRL); Waller H S (math 25% / reading 40%, grade F, #1,029 of 1,632 statewide, top 64%, 2,639 students, 62% FRL).
• Market conditions: Rents soft (-0.7%/yr); 905 active listings in the ZIP; 10 comparable units currently listed for rent nearby; rentals lingering (median 43d on market — plan ~5-8 weeks vacancy on turnover, expect pricing pressure); 80% of comp listings sitting > 30 days — soft ceiling on asking rent; high-income renter base; 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.
• 2 sale attempts 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.
• Cap rate 4.6% vs local median 3.0% in Tomball — 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

• 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?
• It's been on market 86 days. Have you received any prior offers? Is the seller open to a 23% 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.
• Schools are B-rated — typically a magnet for longer-tenancy family renters. What's the average tenant stay here, and is there a school-zone premium baked into asking?
• The area grade is low — what's the realistic commute time and amenity access for the typical tenant pool here? Any planned neighborhood developments (good or bad) we should know about?
• 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.
