What this means for you Summary

Snapshot

  • This is a 2 × 3-bed/1.5-bath units multifamily listed at $500k.

Deal economics

  • At list price, monthly cash flow is $-521 ($-6k/yr) — negative. Per door: $-260/mo.
  • To cash-flow at today's rent, offer at most $408k (18.4% below list).
  • To meet the 1% rule (rent ≥ 1% of price), the offer needs to be $383k (23.4% below list).
  • Recommended offer: $383k (23.4% below list) — sets the bar for 1% rule.

Location & tenants

  • Location reads 74/100 on livability (#67 in CT, #4,936 nationally) — a middle-class / working-renter tenant base. Strengths: health & safety A+, cost of living A, housing A; Watch: crime D, employment D.
  • New Britain School District (suburban): math 6% / reading 17% proficiency, ranked #153 of 153 in CT (top 100%) — low school quality limits family demand, transient renter base, plan for 1-2y turnover; 71% free/reduced lunch — lower-income household profile, screen leases tightly.
  • Zoned schools: Diloreto Elementary & Middle School (math 4% / reading 15%, grade F, #522 of 553 statewide, top 95%, 842 students, 73% FRL); Pulaski Middle School (math 0% / reading 13%, grade F, #171 of 175 statewide, top 98%, 867 students, 80% FRL); New Britain High School (math 10% / reading 31%, grade F, #162 of 194 statewide, top 83%, 2,331 students, 71% FRL) — zoned schools at 75% FRL track the district average.
  • Market conditions: Rents rising fast (+4.9%/yr); 71 active listings in the ZIP; 1,867 units permitted in Capitol Planning Region in 2024 (1,399 in 5+ unit buildings).
  • At $3,829/mo this rent would consume 73% of the median local household income ($63k/yr) (locally 1835% 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 $53k of equity ($3k loan paydown + $50k appreciation (10.0% local appreciation)).
  • By year 2, paydown + projected appreciation supports a ~$86k cash-out refi (75% LTV) — recoverable capital for the next deal without selling this one.

Negotiation context

  • Only 4 days on market — expect competitive offers; lowballing is unlikely to land.
  • Current owner paid $124k; list at $500k implies a 305% gain — meaningful room to come down on a strong offer.
Recommended offer $382,900 (23.4% below list)

Questions for the listing agent

  1. What do current leases actually rent for vs. the listed asking? Can we see a recent rent roll and the last 12 months of T-12 income?
  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 1968 — 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 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?
  7. Crime grade is D 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.
