What this means for you Summary

Snapshot

  • This is a 2 × 2-bed/1.0-bath units multifamily listed at $250k.

Deal economics

  • At list price, monthly cash flow is $420 ($5k/yr) — positive. Per door: $210/mo.
  • The deal already cash-flows at list — no discount required.
  • Meets the 1% rule at list price ($3k rent vs $250k).
  • Recommended offer: $220k (12.0% below list) — sets the bar for market timing.
  • Cap rate 8.3% vs local median 3.7% in Oklahoma City — 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 80/100 on livability (#3 in OK, #1,635 nationally) — a professional / high-income tenant draw. Strengths: amenities A+, commute A+, cost of living A+; Watch: schools F, crime F.
  • Oklahoma City (urban): math 7% / reading 10% proficiency, ranked #254 of 270 in OK (top 94%) — low school quality limits family demand, transient renter base, plan for 1-2y turnover; 82% free/reduced lunch — lower-income household profile, screen leases tightly.
  • Market conditions: Rents rising (+2.9%/yr); 167 active listings in the ZIP; 12 comparable units currently listed for rent nearby; rentals lingering (median 45d on market — plan ~5-8 weeks vacancy on turnover, expect pricing pressure); 58% of comp listings sitting > 30 days — soft ceiling on asking rent; 5,365 units permitted in Oklahoma County in 2024 (569 in 5+ unit buildings).
  • At $2,518/mo this rent would consume 50% of the median local household income ($60k/yr) (locally 892% 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 $2k of loan paydown is wiped out by about $8k of value loss. Plan a longer hold.
  • Oklahoma County population projected at +41% by 2050 — long-run rental-demand tailwind backs the buy-and-hold thesis.

Negotiation context

  • It's been on market 133 days — a 12% lower offer ($220k) is reasonable based on typical stale-listing flexibility.

Risks & watch-outs

  • Watch-outs: built in 1928 — expect roof / HVAC / electrical / plumbing capex.
  • 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.
Recommended offer $220,000 (12.0% below list)

Questions for the listing agent

  1. It's been on market 133 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 1928 — 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.

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.
