What this means for you Summary

Snapshot

• This is a 4-bed/1.5-bath single-family listed at $215k.

Deal economics

• At list price, monthly cash flow is $299 ($4k/yr) — positive.
• The deal already cash-flows at list — no discount required.
• Meets the 1% rule at list price ($2k rent vs $215k).
• Cap rate 8.0% vs local median 2.5% in Porter Heights — 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 65/100 on livability (#663 in TX) — a middle-class / working-renter tenant base. Strengths: crime A+, employment A+, cost of living A+; Watch: schools F, amenities F, commute F.
• New Caney ISD (suburban): math 31% / reading 32% proficiency, ranked #570 of 826 in TX (top 69%) — families likely to look elsewhere, expect single-tenant / working-renter base with shorter leases.
• Market conditions: Rents rising (+1.6%/yr); 941 active listings in the ZIP; solid renter incomes; 13,259 units permitted in Montgomery County in 2024 (1,402 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.
• Montgomery County population projected at +65% by 2050 — long-run rental-demand tailwind backs the buy-and-hold thesis.

Negotiation context

• Only 1 days on market — expect competitive offers; lowballing is unlikely to land.
• 3 sale attempts; this cycle's ask has dropped $173k (45%) from the opening price — seller is motivated, your offer sets the floor, not the list.

Risks & watch-outs

• Climate carrying-cost: 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.

Recommended offer $215,001

Questions for the listing agent

1. Built in 1970 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
2. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
3. 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?
4. 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.
5. 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.
6. 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.
