What this means for you Summary

Snapshot

  • This is a 2 × 2-bed/2.0-bath units multifamily listed at $215k.

Deal economics

  • At list price, monthly cash flow is $245 ($3k/yr) — positive. Per door: $122/mo.
  • The deal already cash-flows at list — no discount required.
  • To meet the 1% rule (rent ≥ 1% of price), the offer needs to be $208k (3.3% below list).
  • Recommended offer: $208k (3.3% below list) — sets the bar for 1% rule.
  • Cap rate 7.7% 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 C — 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: Oak Hill Elem. (math 12% / reading 12%, grade F, #1,016 of 1,115 statewide, top 92%, 238 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 (+2.6%/yr); 255 active listings in the ZIP; 27 comparable units currently listed for rent nearby; rentals at typical pace (median 15d 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 41% 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 $6k 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.

Negotiation context

  • It's been on market 39 days — a 3% lower offer ($209k) is reasonable based on typical stale-listing flexibility.

Risks & watch-outs

  • Watch-outs: built in 1923 — 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 $207,800 (3.3% below list)

Questions for the listing agent

  1. It's been on market 39 days. Have you received any prior offers? Is the seller open to a 3% concession, seller financing, or rate buy-down credit?
  2. Can we see the unit-by-unit rent roll, current vacancy, and any below-market leases? What's the average tenancy length?
  3. What capital expenditures (roof, boiler, parking lot, exteriors) have been made in the last 5 years, and what's planned in the next 2?
  4. Built in 1923 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
  5. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
  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 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.
