What this means for you Summary

Snapshot

  • This is a 2 × 2-bed/1-bath units multifamily listed at $445k.

Deal economics

  • At list price, monthly cash flow is $148 ($2k/yr) — positive. Per door: $74/mo.
  • The deal already cash-flows at list — no discount required.
  • To meet the 1% rule (rent ≥ 1% of price), the offer needs to be $410k (7.8% below list).
  • Recommended offer: $410k (7.8% below list) — sets the bar for 1% rule.
  • Cap rate 6.7% 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 (+2.6%/yr); 140 active listings in the ZIP; 34 comparable units currently listed for rent nearby; rentals lingering (median 45d on market — plan ~5-8 weeks vacancy on turnover, expect pricing pressure); 53% of comp listings sitting > 30 days — soft ceiling on asking rent; 1,059 units permitted in South Central Connecticut Planning Region in 2024 (779 in 5+ unit buildings).
  • At $4,105/mo this rent would consume 82% of the median local household income ($60k/yr) (locally 4999% 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 $13k of value loss. Plan a longer hold.

Negotiation context

  • It's been on market 40 days — a 3% lower offer ($432k) is reasonable based on typical stale-listing flexibility.
  • Current owner paid $145k; list at $445k implies a 207% gain — meaningful room to come down on a strong offer.

Risks & watch-outs

  • Watch-outs: built in 1890 — expect roof / HVAC / electrical / plumbing capex.
  • Climate carrying-cost: major wind risk, 55% chance of damaging wind over 30y; extreme-heat days projected 7→17/yr by 2055 (HVAC capex compounding) — expect insurance premiums to compound above CPI over the hold.
Recommended offer $410,500 (7.8% below list)

Questions for the listing agent

  1. It's been on market 40 days. Have you received any prior offers? Is the seller open to a 8% 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 1890 — 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. The area grade is low — what's the realistic commute time and amenity access for the typical tenant pool here? Any planned neighborhood developments (good or bad) we should know about?
  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.
