What this means for you Summary

Snapshot

  • This is a 2 × 2-bed/1.0-bath units multifamily listed at $130k.

Deal economics

  • At list price, monthly cash flow is $679 ($8k/yr) — positive. Per door: $339/mo.
  • The deal already cash-flows at list — no discount required.
  • Meets the 1% rule at list price ($2k rent vs $130k).
  • Cap rate 12.6% vs local median 10.1% in Detroit — meaningfully above typical; check what's discounted (condition, days-on-market, listing class) to confirm the premium yield is real.

Location & tenants

  • Location reads 73/100 on livability (#218 in MI) — a middle-class / working-renter tenant base. Strengths: amenities A+, commute A+, cost of living A+; Watch: schools F, crime F, employment F.
  • Detroit Public Schools Community District (urban): math 10% / reading 24% proficiency, ranked #499 of 540 in MI (top 92%) — low school quality limits family demand, transient renter base, plan for 1-2y turnover; 90% free/reduced lunch — lower-income household profile, screen leases tightly.
  • Market conditions: 300 active listings in the ZIP; 1 comparable units currently listed for rent nearby; lower-income renter base — watch delinquency; 2,639 units permitted in Wayne County in 2024 (1,216 in 5+ unit buildings).
  • At $2,091/mo this rent would consume 75% of the median local household income ($34k/yr) (locally 1364% 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 $899 of loan paydown is wiped out by about $4k of value loss. Plan a longer hold.
  • Wayne County population projected at -17% by 2050 — secular population decline; favor cash flow + early exit over multi-decade hold.
  • At projected returns (-3.0% appreciation + 3.0% rent growth), your $36k cash investment doubles in ~6 years — after that, you're playing with house money.

Negotiation context

  • Only 13 days on market — expect competitive offers; lowballing is unlikely to land.
  • 10 sale attempts since 12y 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 $70k; list at $130k implies a 86% gain — meaningful room to come down on a strong offer.

Risks & watch-outs

  • Watch-outs: built in 1916 — expect roof / HVAC / electrical / plumbing capex.
Recommended offer $130,000

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 1916 — 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. 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?
  6. 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?
  7. 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.
  8. 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.
  9. 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.
