What this means for you Summary

Snapshot

  • This is a 4 × 2-bed/1.0-bath units multifamily listed at $500k.

Deal economics

  • At list price, monthly cash flow is $754 ($9k/yr) — positive. Per door: $189/mo.
  • The deal already cash-flows at list — no discount required.
  • Meets the 1% rule at list price ($6k rent vs $500k).
  • Cap rate 8.1% vs local median 4.5% in Maywood — 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 78/100 on livability (#146 in IL, #2,694 nationally) — a middle-class / working-renter tenant base. Strengths: commute A+, cost of living A+, housing A+; Watch: health & safety C-, crime D+, schools F.
  • Maywood-Melrose Park-Broadview 89 (suburban): math 14% / reading 21% proficiency, ranked #738 of 919 in IL (top 80%) — low school quality limits family demand, transient renter base, plan for 1-2y turnover; 74% free/reduced lunch — lower-income household profile, screen leases tightly.
  • Market conditions: 72 active listings in the ZIP; 6,272 units permitted in Cook County in 2024 (4,658 in 5+ unit buildings).
  • At $6,128/mo this rent would consume 107% of the median local household income ($69k/yr) (locally 869% 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 $3k of loan paydown is wiped out by about $15k of value loss. Plan a longer hold.

Negotiation context

  • Only 10 days on market — expect competitive offers; lowballing is unlikely to land.
  • 5 sale attempts since 17y ago 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 $289k; list at $500k implies a 73% gain — meaningful room to come down on a strong offer.

Risks & watch-outs

  • Watch-outs: property tax is 3.0% of price.
  • Climate carrying-cost: moderate flood risk — expect insurance premiums to compound above CPI over the hold.
Recommended offer $500,000

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 1965 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
  4. Property tax is high relative to price — has the assessment been appealed recently, and will the sale trigger a re-assessment?
  5. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
  6. Schools are F-rated, which usually means shorter tenancies and higher turnover. Who's the typical renter profile here, and what's been the actual vacancy rate?
  7. Crime grade is D in this area — have there been break-ins, vandalism, or insurance claims at this property in the last 3 years? What carrier currently insures it and at what premium?
  8. 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.
  9. 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.
  10. 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.
