What this means for you Summary

Snapshot

  • This is a 3-bed/1.5-bath single-family listed at $70k.

Deal economics

  • At list price, monthly cash flow is $514 ($6k/yr) — positive.
  • The deal already cash-flows at list — no discount required.
  • Meets the 1% rule at list price ($1k rent vs $70k).
  • Recommended offer: $66k (6.0% below list) — sets the bar for market timing.

Location & tenants

  • Location reads 64/100 on livability (#313 in MO) — a middle-class / working-renter tenant base. Strengths: cost of living A+, crime B; Watch: schools F, amenities F, commute F.
  • Riverview Gardens (suburban): math 2% / reading 9% proficiency, ranked #324 of 324 in MO (top 100%) — low school quality limits family demand, transient renter base, plan for 1-2y turnover; 90% free/reduced lunch — lower-income household profile, screen leases tightly.
  • Market conditions: Rents rising fast (+5.0%/yr); 372 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); lower-income renter base — watch delinquency; 920 units permitted in St. Louis County in 2024 (250 in 5+ unit buildings).
  • This rent runs 38% of the median local income ($41k/yr) — at the standard rent-burdened threshold; future hikes will face affordability resistance.

Forward outlook

  • In year one you build about $3k of equity ($483 loan paydown + $3k appreciation (3.8% local appreciation)).
  • At projected returns (3.8% appreciation + 5.0% rent growth), your $20k cash investment doubles in ~3 years — after that, you're playing with house money.
  • By year 10, paydown + projected appreciation supports a ~$31k cash-out refi (75% LTV) — recoverable capital for the next deal without selling this one.

Negotiation context

  • It's been on market 90 days — a 6% lower offer ($66k) is reasonable based on typical stale-listing flexibility.
  • 3 sale attempts since 2y ago; this cycle's ask has dropped $20k (22%) from the opening price — seller is motivated, your offer sets the floor, not the list.
  • Current owner paid $25k; list at $70k implies a 180% gain — meaningful room to come down on a strong offer.

Risks & watch-outs

  • 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.
Recommended offer $65,706 (6.0% below list)

Questions for the listing agent

  1. It's been on market 90 days. Have you received any prior offers? Is the seller open to a 6% concession, seller financing, or rate buy-down credit?
  2. Built in 1965 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
  3. Why hasn't it sold? Are there any deal-killer items the seller is aware of (foundation, flood, title, zoning, code violations)?
  4. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
  5. 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?
  6. 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.
  7. 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.
  8. 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.
