Investor read

• This is a 2-bed/1.0-bath single-family listed at $90k.
• At list price, monthly cash flow is $252 ($3k/yr) — positive.
• The deal already cash-flows at list — no discount required.
• Meets the 1% rule at list price ($1k rent vs $90k).
• It's been on market 15 days — a 2% lower offer ($88k) is reasonable based on typical stale-listing flexibility.
• Recommended offer: $88k (1.5% below list) — sets the bar for market timing.
• Local home prices are declining (-3.0%/yr); year-one equity from $619 of loan paydown is wiped out by about $3k of value loss. Plan a longer hold.
• Location reads: area grade C — affects rentability + tenant quality, not the cash-flow math above.
• St. Louis City (urban): math 10% / reading 18% proficiency, ranked #312 of 324 in MO (top 96%) — low school quality limits family demand, transient renter base, plan for 1-2y turnover; 80% free/reduced lunch — lower-income household profile, screen leases tightly.
• Zoned schools: Monroe Elem. (math 2% / reading 2%, grade F, #1,099 of 1,115 statewide, top 100%, 158 students, 98% FRL); Roosevelt High (math 2% / reading 8%, grade F, #517 of 521 statewide, top 100%, 460 students, 99% FRL) — zoned schools average 99% FRL vs 80% district-wide (18 pts higher); higher-poverty schools than district average — tighter screening recommended.
• Watch-outs: built in 1882 — expect roof / HVAC / electrical / plumbing capex.
• Market conditions: Rents rising fast (+4.9%/yr); 240 active listings in the ZIP; 40 comparable units currently listed for rent nearby; rentals at typical pace (median 24d on market — plan ~3-4 weeks tenant-placement turnaround); 294 units permitted in St. Louis city in 2024 (227 in 5+ unit buildings).
• St. Louis County population projected to shrink 6% by 2050 — rents likely to lag national; underwrite the cash flow, not the appreciation.
• At projected returns (-3.0% appreciation + 4.9% rent growth), your $25k cash investment doubles in ~8 years — after that, you're playing with house money.
• Climate carrying-cost: extreme-heat days projected 7→21/yr by 2055 (HVAC capex compounding) — expect insurance premiums to compound above CPI over the hold.
• Cap rate 9.7% vs local median 5.0% in St. Louis — 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

• Built in 1882 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
• Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
• 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.
