Investor read

• This is a ?-bed/2.0-bath single-family listed at $40k.
• At list price, monthly cash flow is $668 ($8k/yr) — positive.
• The deal already cash-flows at list — no discount required.
• Meets the 1% rule at list price ($1k rent vs $40k).
• It's been on market 235 days — a 12% lower offer ($35k) is reasonable based on typical stale-listing flexibility.
• Recommended offer: $35k (12.0% below list) — sets the bar for market timing.
• Local home prices are declining (-1.8%/yr); year-one equity from $277 of loan paydown is wiped out by about $701 of value loss. Plan a longer hold.
• Location reads: area grade B — 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.
• Watch-outs: built in 1912 — expect roof / HVAC / electrical / plumbing capex.
• Market conditions: 58 active listings in the ZIP; 4 comparable units currently listed for rent nearby; rentals at typical pace (median 25d 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.
• 3 sale attempts since 2y ago; this cycle's ask has dropped $10k (20%) from the opening price — seller is motivated, your offer sets the floor, not the list.
• Current owner paid $21k; list at $40k implies a 90% gain — meaningful room to come down on a strong offer.
• At projected returns (-1.8% appreciation + 3.0% rent growth), your $11k cash investment doubles in ~2 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 26.3% 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

• It's been on market 235 days. Have you received any prior offers? Is the seller open to a 12% concession, seller financing, or rate buy-down credit?
• Built in 1912 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
• 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.
• 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.
