What this means for you Summary
Snapshot
- This is a 2 × 2-bed/1-bath units multifamily listed at $155k.
Deal economics
- At list price, monthly cash flow is $484 ($6k/yr) — positive. Per door: $242/mo.
- The deal already cash-flows at list — no discount required.
- Meets the 1% rule at list price ($2k rent vs $155k).
- Recommended offer: $150k (3.0% below list) — sets the bar for market timing.
- Cap rate 10.0% 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.
Location & tenants
- 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.
- Market conditions: Rents rising (+2.6%/yr); 255 active listings in the ZIP; 16 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).
- This rent runs 37% of the median local income ($61k/yr) — at the standard rent-burdened threshold; future hikes will face affordability resistance.
Forward outlook
- Local home prices are declining (-3.0%/yr); year-one equity from $1k of loan paydown is wiped out by about $5k of value loss. Plan a longer hold.
- 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 + 2.6% rent growth), your $43k cash investment doubles in ~9 years — after that, you're playing with house money.
Negotiation context
- It's been on market 59 days — a 3% lower offer ($150k) is reasonable based on typical stale-listing flexibility.
- 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.
- Current owner paid $90k; list at $155k implies a 72% gain — meaningful room to come down on a strong offer.
Risks & watch-outs
- Watch-outs: built in 1927 — expect roof / HVAC / electrical / plumbing capex.
- 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.
Questions for the listing agent
- It's been on market 59 days. Have you received any prior offers? Is the seller open to a 3% concession, seller financing, or rate buy-down credit?
- Can we see the unit-by-unit rent roll, current vacancy, and any below-market leases? What's the average tenancy length?
- What capital expenditures (roof, boiler, parking lot, exteriors) have been made in the last 5 years, and what's planned in the next 2?
- Built in 1927 — 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 apartment / multifamily construction is in the pipeline within 1–3 miles? Heavy new supply (>2% of stock underway) typically softens rents 12–24 months out; light construction supports rent growth.

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.
