🏢 Co-op / cooperative unit. The $264,900 price buys shares in the cooperative corporation, not the real estate itself — so it isn't comparable to a fee-simple sale price, and the cashflow / cap-rate / 1%-rule cards below (which assume you own the property and can rent it out) don't apply here. Expect board approval and a monthly maintenance fee on top of the price.

What this means for you Summary

Snapshot

  • This is a 1-bed/1.0-bath condo listed at $265k. Condition is rated fair.

Deal economics

  • At list price, monthly cash flow is $-142 ($-2k/yr) — negative.
  • To cash-flow at today's rent, offer at most $244k (7.8% below list).
  • To meet the 1% rule (rent ≥ 1% of price), the offer needs to be $221k (16.7% below list).
  • Recommended offer: $221k (16.7% below list) — sets the bar for 1% rule.
  • Cap rate 5.9% vs local median 2.5% in North Valley Stream — 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 80/100 on livability (#120 in NY, #1,949 nationally) — a professional / high-income tenant draw. Strengths: commute A+, employment A+, housing A+; Watch: amenities F, cost of living F.
  • Sewanhaka Central High School District (suburban): math 76% / reading 83% proficiency, ranked #43 of 590 in NY (top 7%) — strong family-tenant draw, lease renewals of 3-5y typical; only 19% free/reduced lunch — higher-income household profile.
  • Zoned schools: Elmont Memorial High School (math 81% / reading 83%, grade A, #452 of 1,100 statewide, top 44%, 1,501 students, 48% FRL) — zoned schools average 48% FRL vs 19% district-wide (29 pts higher); higher-poverty schools than district average — tighter screening recommended.
  • Market conditions: Rents rising (+1.9%/yr); 172 active listings in the ZIP; 1 comparable units currently listed for rent nearby; high-income renter base; 824 units permitted in Nassau County in 2024 (153 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.
  • Nassau County population projected at +7% by 2050 — modest demand growth; plan on rents tracking national, not racing it.

Negotiation context

  • It's been on market 64 days — a 6% lower offer ($249k) is reasonable based on typical stale-listing flexibility.
  • 2 sale attempts 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.

Risks & watch-outs

  • Watch-outs: flood insurance adds $56/mo; built in 1959 — expect roof / HVAC / electrical / plumbing capex.
  • Climate carrying-cost: major flood risk; major wind risk, 54% 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 $220,723 (16.7% 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. It's been on market 64 days. Have you received any prior offers? Is the seller open to a 17% concession, seller financing, or rate buy-down credit?
  3. Have any recent inspections been done? Can we get a copy of the seller's disclosures and any deferred-maintenance estimates?
  4. Built in 1959 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
  5. What's the actual annual flood-insurance premium (NFIP or private), and is the property in a SFHA with mandatory coverage?
  6. Any open or pending special assessments — roof, HVAC, plumbing, elevator, façade? What's the per-unit balance and payoff schedule, and is the seller paying it off at close or rolling it to the buyer?
  7. Why hasn't it sold? Are there any deal-killer items the seller is aware of (foundation, flood, title, zoning, code violations)?
  8. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
  9. 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?
  10. 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?
  11. 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.
  12. 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.
  13. 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.
