What this means for you Summary
Snapshot
- This is a 2 × 2-bed/1-bath units multifamily listed at $158k.
Deal economics
- At list price, monthly cash flow is $2k ($25k/yr) — positive. Per door: $1k/mo.
- The deal already cash-flows at list — no discount required.
- Meets the 1% rule at list price ($4k rent vs $158k).
- Recommended offer: $153k (3.0% below list) — sets the bar for market timing.
- Cap rate 21.9% vs local median 4.9% in University City — 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 73/100 on livability (#84 in MO) — a middle-class / working-renter tenant base. Strengths: employment A+, housing A+, cost of living B; Watch: amenities D-, commute D-, health & safety F.
- University City (suburban): math 15% / reading 26% proficiency, ranked #297 of 324 in MO (top 92%) — low school quality limits family demand, transient renter base, plan for 1-2y turnover; 67% free/reduced lunch — lower-income household profile, screen leases tightly.
- Zoned schools: Pershing Elem. (math 8% / reading 12%, grade F, #1,037 of 1,115 statewide, top 94%, 265 students, 100% FRL); University City Sr. High (math 5% / reading 52%, grade F, #409 of 521 statewide, top 79%, 726 students, 100% FRL) — zoned schools average 100% FRL vs 67% district-wide (32 pts higher); higher-poverty schools than district average — tighter screening recommended.
- Market conditions: 1 active listings in the ZIP; 4 comparable units currently listed for rent nearby; rentals at typical pace (median 24d on market — plan ~3-4 weeks tenant-placement turnaround); 920 units permitted in St. Louis County in 2024 (250 in 5+ unit buildings).
Forward outlook
- In year one you build about $6k of equity ($1k loan paydown + $5k appreciation (3.0% local appreciation)).
- At projected returns (3.0% appreciation + 3.0% rent growth), your $44k cash investment doubles in ~2 years — after that, you're playing with house money.
- By year 6, 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 34 days — a 3% lower offer ($153k) is reasonable based on typical stale-listing flexibility.
- Current owner paid $76k; list at $158k implies a 108% gain — meaningful room to come down on a strong offer.
Risks & watch-outs
- Watch-outs: built in 1908 — expect roof / HVAC / electrical / plumbing capex.
- Climate carrying-cost: major flood risk; 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 34 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 1908 — 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.
- Schools are B-rated — typically a magnet for longer-tenancy family renters. What's the average tenant stay here, and is there a school-zone premium baked into asking?
- 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.
