What this means for you Summary

Snapshot

  • This is a 2 × 2.0-bed/1.0-bath units multifamily listed at $439k.

Deal economics

  • At list price, monthly cash flow is $760 ($9k/yr) — positive. Per door: $380/mo.
  • The deal already cash-flows at list — no discount required.
  • Meets the 1% rule at list price ($5k rent vs $439k).
  • Recommended offer: $426k (3.0% below list) — sets the bar for market timing.
  • Cap rate 8.4% vs local median 4.9% in New Haven — 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 79/100 on livability (#31 in CT, #2,190 nationally) — a middle-class / working-renter tenant base. Strengths: amenities A+, commute A+, health & safety A+; Watch: schools D+, employment D, crime F.
  • New Haven School District (urban): math 12% / reading 25% proficiency, ranked #147 of 153 in CT (top 96%) — low school quality limits family demand, transient renter base, plan for 1-2y turnover; 66% free/reduced lunch — lower-income household profile, screen leases tightly.
  • Market conditions: Rents rising (+3.3%/yr); 45 active listings in the ZIP; 7 comparable units currently listed for rent nearby; rentals at typical pace (median 16d on market — plan ~3-4 weeks tenant-placement turnaround); 1,059 units permitted in South Central Connecticut Planning Region in 2024 (779 in 5+ unit buildings).
  • At $4,732/mo this rent would consume 114% of the median local household income ($50k/yr) (locally 1321% of renters already pay >50% of income on rent) — very limited rent-growth headroom before tenants either downsize or default.

Forward outlook

  • In year one you build about $46k of equity ($3k loan paydown + $43k appreciation (9.8% local appreciation)).
  • At projected returns (9.8% appreciation + 3.3% rent growth), your $123k cash investment doubles in ~3 years — after that, you're playing with house money.
  • By year 2, paydown + projected appreciation supports a ~$74k cash-out refi (75% LTV) — recoverable capital for the next deal without selling this one.

Negotiation context

  • It's been on market 52 days — a 3% lower offer ($426k) is reasonable based on typical stale-listing flexibility.
  • 2 sale attempts 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 $24k; list at $439k implies a 1722% gain — meaningful room to come down on a strong offer.

Risks & watch-outs

  • Watch-outs: built in 1900 — expect roof / HVAC / electrical / plumbing capex.
  • Climate carrying-cost: major wind risk, 58% chance of damaging wind over 30y; extreme-heat days projected 7→16/yr by 2055 (HVAC capex compounding) — expect insurance premiums to compound above CPI over the hold.
Recommended offer $425,830 (3.0% below list)

Questions for the listing agent

  1. It's been on market 52 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 1900 — 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. Schools are D-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 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?
  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.
