What this means for you Summary

Snapshot

  • This is a 2 × 3-bed/2.0-bath units multifamily listed at $750k.

Deal economics

  • At list price, monthly cash flow is $882 ($11k/yr) — positive. Per door: $441/mo.
  • The deal already cash-flows at list — no discount required.
  • Meets the 1% rule at list price ($8k rent vs $750k).

Location & tenants

  • Location reads 78/100 on livability (#160 in NY, #2,453 nationally) — a middle-class / working-renter tenant base. Strengths: amenities A+, commute A+, employment A+; Watch: cost of living F.
  • Island Park Union Free School District (suburban): math 43% / reading 62% proficiency, ranked #300 of 590 in NY (top 51%) — acceptable for families but not a draw, mixed tenant base, ~2y average lease.
  • Zoned schools: Francis X Hegarty Elementary School (math 42% / reading 72%, grade C+, #842 of 2,108 statewide, top 43%, 415 students, 34% FRL); Island Park Lincoln Orens Middle School (math 42% / reading 57%, grade C, #280 of 729 statewide, top 40%, 271 students, 44% FRL).
  • Market conditions: 43 active listings in the ZIP; high-income renter base; 824 units permitted in Nassau County in 2024 (153 in 5+ unit buildings).
  • At $7,925/mo this rent would consume 86% of the median local household income ($111k/yr) (locally 371% 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 $5k of loan paydown is wiped out by about $22k of value loss. Plan a longer hold.
  • Nassau County population projected at +7% by 2050 — modest demand growth; plan on rents tracking national, not racing it.

Negotiation context

  • Only 10 days on market — expect competitive offers; lowballing is unlikely to land.
  • 6 sale attempts since 12y ago 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 $600k; 25% above their basis — modest negotiation headroom, anchor on the comps not their cost.

Risks & watch-outs

  • Watch-outs: flood insurance adds $460/mo; built in 1948 — expect roof / HVAC / electrical / plumbing capex.
  • Climate carrying-cost: in FEMA flood zone AE (mandatory federal flood insurance); severe wind risk, 80% 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 $750,000

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 1948 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
  4. What's the actual annual flood-insurance premium (NFIP or private), and is the property in a SFHA with mandatory coverage?
  5. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
  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.
