What this means for you Summary

Snapshot

  • This is a 2 × 3-bed/3.0-bath units multifamily listed at $600k.

Deal economics

  • At list price, monthly cash flow is $2k ($18k/yr) — positive. Per door: $753/mo.
  • The deal already cash-flows at list — no discount required.
  • Meets the 1% rule at list price ($7k rent vs $600k).
  • Cap rate 9.3% vs local median 3.0% in Lindenhurst — 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 75/100 on livability (#260 in NY, #4,112 nationally) — a middle-class / working-renter tenant base. Strengths: commute A+, employment A+, housing A+; Watch: amenities D+, cost of living F, health & safety F.
  • Lindenhurst Union Free School District (suburban): math 64% / reading 72% proficiency, ranked #139 of 590 in NY (top 24%) — acceptable for families but not a draw, mixed tenant base, ~2y average lease.
  • Zoned schools: West Gates Avenue School (math 54% / reading 74%, grade B, #591 of 2,108 statewide, top 31%, 278 students, 43% FRL); Lindenhurst Middle School (math 45% / reading 62%, grade C+, #228 of 729 statewide, top 31%, 1,284 students, 44% FRL); Lindenhurst Senior High School (math 86% / reading 95%, grade A+, #231 of 1,100 statewide, top 21%, 1,897 students, 41% FRL) — zoned schools average 43% FRL vs 21% district-wide (22 pts higher); higher-poverty schools than district average — tighter screening recommended.
  • Market conditions: 204 active listings in the ZIP; high-income renter base; 1,366 units permitted in Suffolk County in 2024 (216 in 5+ unit buildings).
  • At $7,193/mo this rent would consume 67% of the median local household income ($128k/yr) (locally 580% 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 $4k of loan paydown is wiped out by about $18k of value loss. Plan a longer hold.
  • Suffolk County population projected to shrink 5% by 2050 — rents likely to lag national; underwrite the cash flow, not the appreciation.

Negotiation context

  • Only 12 days on market — expect competitive offers; lowballing is unlikely to land.
  • Current owner paid $255k; list at $600k implies a 135% gain — meaningful room to come down on a strong offer.

Risks & watch-outs

  • Watch-outs: built in 1940 — expect roof / HVAC / electrical / plumbing capex.
  • Climate carrying-cost: major wind risk, 61% 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 $599,999

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 1940 — 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 B-rated — typically a magnet for longer-tenancy family renters. What's the average tenant stay here, and is there a school-zone premium baked into asking?
  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.
