Investor read

• This is a 4 × 3-bed/1.0-bath units multifamily listed at $450k.
• At list price, monthly cash flow is $2k ($22k/yr) — positive. Per door: $460/mo.
• The deal already cash-flows at list — no discount required.
• Meets the 1% rule at list price ($6k rent vs $450k).
• It's been on market 54 days — a 3% lower offer ($436k) is reasonable based on typical stale-listing flexibility.
• Recommended offer: $436k (3.0% below list) — sets the bar for market timing.
• Local home prices are declining (-3.0%/yr); year-one equity from $3k of loan paydown is wiped out by about $14k 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.
• Zoned schools: Mann Elem. (math 8% / reading 12%, grade F, #1,037 of 1,115 statewide, top 94%, 240 students, 99% FRL); Gateway Middle (math 0% / reading 8%, grade F, #389 of 391 statewide, top 100%, 506 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 (19 pts higher); higher-poverty schools than district average — tighter screening recommended.
• Watch-outs: built in 1912 — expect roof / HVAC / electrical / plumbing capex.
• Market conditions: Rents rising (+2.6%/yr); 261 active listings in the ZIP; 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.
• 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.
• At projected returns (-3.0% appreciation + 2.6% rent growth), your $126k cash investment doubles in ~8 years — after that, you're playing with house money.
• Climate carrying-cost: extreme-heat days projected 7→19/yr by 2055 (HVAC capex compounding) — expect insurance premiums to compound above CPI over the hold.
• Cap rate 11.2% 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.
• At $5,934/mo this rent would consume 116% of the median local household income ($61k/yr) (locally 1923% of renters already pay >50% of income on rent) — very limited rent-growth headroom before tenants either downsize or default.

Questions for listing agent

• It's been on market 54 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 1912 — 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.
