What this means for you Summary

Snapshot

  • This is a 2 × 2-bed/1.0-bath units multifamily listed at $275k.

Deal economics

  • At list price, monthly cash flow is $797 ($10k/yr) — positive. Per door: $398/mo.
  • The deal already cash-flows at list — no discount required.
  • Meets the 1% rule at list price ($3k rent vs $275k).
  • Cap rate 9.8% vs local median 3.5% in Putnam — 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 66/100 on livability (#117 in CT) — a middle-class / working-renter tenant base. Strengths: crime A+, housing A+, cost of living A; Watch: health & safety D+, amenities F, commute F.
  • Putnam School District (suburban): math 25% / reading 34% proficiency, ranked #126 of 153 in CT (top 82%) — low school quality limits family demand, transient renter base, plan for 1-2y turnover.
  • Zoned schools: Putnam Elementary School (math 31% / reading 33%, grade F, #361 of 553 statewide, top 68%, 571 students, 57% FRL); Putnam High School (math 34% / reading 54%, grade F, #94 of 194 statewide, top 49%, 253 students, 48% FRL) — zoned schools at 53% FRL track the district average.
  • Market conditions: 58 active listings in the ZIP; 149 units permitted in Northeastern Connecticut Planning Region in 2024 (0 in 5+ unit buildings).

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.
  • At projected returns (-3.0% appreciation + 3.0% rent growth), your $77k cash investment doubles in ~10 years — after that, you're playing with house money.

Negotiation context

  • Only 5 days on market — expect competitive offers; lowballing is unlikely to land.
  • Current owner paid $35k; list at $275k implies a 686% gain — meaningful room to come down on a strong offer.

Risks & watch-outs

  • Watch-outs: built in 1907 — expect roof / HVAC / electrical / plumbing capex.
  • Climate carrying-cost: major wind risk, 53% chance of damaging wind over 30y — expect insurance premiums to compound above CPI over the hold.
Recommended offer $275,000

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 1907 — 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 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?
  6. 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.
  7. 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.
  8. 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.
