What this means for you Summary

Snapshot

• This is a 2 × 3-bed/2.0-bath units multifamily listed at $270k.

Deal economics

• At list price, monthly cash flow is $873 ($10k/yr) — positive. Per door: $436/mo.
• The deal already cash-flows at list — no discount required.
• Meets the 1% rule at list price ($3k rent vs $270k).
• Cap rate 10.2% 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.
• Zoned schools: Sigel Elem. Comm. Ed. Ctr. (math 2% / reading 2%, grade F, #1,099 of 1,115 statewide, top 100%, 219 students, 99% 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.
• Market conditions: Rents rising fast (+7.5%/yr); 165 active listings in the ZIP; 1 comparable units currently listed for rent nearby; 294 units permitted in St. Louis city in 2024 (227 in 5+ unit buildings).
• At $3,224/mo this rent would consume 56% of the median local household income ($69k/yr) (locally 1429% of renters already pay >50% of income on rent) — very limited rent-growth headroom before tenants either downsize or default.

Forward outlook

• Local home prices are declining (-3.0%/yr); year-one equity from $2k of loan paydown is wiped out by about $8k 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 + 7.5% rent growth), your $76k cash investment doubles in ~7 years — after that, you're playing with house money.

Negotiation context

• Only 6 days on market — expect competitive offers; lowballing is unlikely to land.

Risks & watch-outs

• Watch-outs: built in 1910 — 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.

Recommended offer $269,900

Questions for the listing agent

1. Can we see the unit-by-unit rent roll, current vacancy, and any below-market leases? What's the average tenancy length?
2. What capital expenditures (roof, boiler, parking lot, exteriors) have been made in the last 5 years, and what's planned in the next 2?
3. Built in 1910 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
4. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
5. 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.
6. 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.
7. 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.
