What this means for you Summary

Snapshot

  • This is a 2 × 3-bed/1.0-bath units multifamily listed at $175k.

Deal economics

  • At list price, monthly cash flow is $2k ($29k/yr) — positive. Per door: $1k/mo.
  • The deal already cash-flows at list — no discount required.
  • Meets the 1% rule at list price ($5k rent vs $175k).
  • Recommended offer: $154k (12.0% below list) — sets the bar for market timing.
  • Cap rate 23.0% vs local median 6.7% in Calumet Park — 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 72/100 on livability (#308 in IL) — a middle-class / working-renter tenant base. Strengths: commute A+, cost of living A+, housing A+; Watch: employment C-, schools F, crime F.
  • Chsd 218 (suburban): math 14% / reading 20% proficiency, ranked #454 of 620 in IL (top 73%) — low school quality limits family demand, transient renter base, plan for 1-2y turnover.
  • Market conditions: Rents rising fast (+7.8%/yr); 76 active listings in the ZIP; 1 comparable units currently listed for rent nearby; lower-income renter base — watch delinquency; 6,272 units permitted in Cook County in 2024 (4,658 in 5+ unit buildings).
  • At $4,624/mo this rent would consume 149% of the median local household income ($37k/yr) (locally 1868% 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 $1k of loan paydown is wiped out by about $5k of value loss. Plan a longer hold.
  • At projected returns (-3.0% appreciation + 7.8% rent growth), your $49k cash investment doubles in ~2 years — after that, you're playing with house money.

Negotiation context

  • It's been on market 140 days — a 12% lower offer ($154k) is reasonable based on typical stale-listing flexibility.
  • 10 sale attempts since 20y 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 $140k; 25% above their basis — modest negotiation headroom, anchor on the comps not their cost.

Risks & watch-outs

  • Watch-outs: built in 1924 — expect roof / HVAC / electrical / plumbing capex.
Recommended offer $154,000 (12.0% below list)

Questions for the listing agent

  1. It's been on market 140 days. Have you received any prior offers? Is the seller open to a 12% 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 1924 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
  5. Why hasn't it sold? Are there any deal-killer items the seller is aware of (foundation, flood, title, zoning, code violations)?
  6. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
  7. 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?
  8. Crime grade is F 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?
  9. 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.
  10. 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.
  11. 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.

    Both tenants paying rent. Opportunity to duplex up to partially finished attic for large master bedroom suite. Opportunity to add air conditioning to existing forced air furnaces for both units. First floor recently updated and the whole building was updated as of 2008. Tenants pay heat, electric and gas and they each have their own laundry hookup in the full basement attached to their own utilities. Hardwood floors and large kitchens accompany 3 bedrooms on the first floor. 2 bay window and 3 bedrooms with a large eat in kitchen on the second floor. Tear off roof in 2018 so you won't need to worry about that until 2038. Electric is on breaker boxes. Both the wide building lot and double side lot are fenced together. Taxes are being contested. Everything is ready for the new investor to start collecting rent or make some easy upgrades to increase rent once the contracts expire.

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.
