What this means for you Summary
Snapshot
- This is a 2 × 3-bed/1.5-bath units multifamily listed at $775k.
Deal economics
- At list price, monthly cash flow is $614 ($7k/yr) — positive. Per door: $307/mo.
- The deal already cash-flows at list — no discount required.
- To meet the 1% rule (rent ≥ 1% of price), the offer needs to be $743k (4.1% below list).
- Recommended offer: $743k (4.1% below list) — sets the bar for 1% rule.
- Cap rate 7.2% vs local median 3.2% in Lynbrook — 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 88/100 on livability (#10 in NY, #221 nationally) — a professional / high-income tenant draw. Strengths: crime A+, amenities A+, commute A+; Watch: cost of living F.
- Lynbrook Union Free School District (suburban): math 75% / reading 73% proficiency, ranked #72 of 590 in NY (top 12%) — strong family-tenant draw, lease renewals of 3-5y typical; only 8% free/reduced lunch — higher-income household profile.
- Zoned schools: West End School (math 82% / reading 82%, grade A+, #138 of 2,108 statewide, top 8%, 401 students, 0% FRL); Lynbrook North Middle School (math 42% / reading 67%, grade B-, #214 of 729 statewide, top 31%, 266 students, 15% FRL); Lynbrook Senior High School (math 97% / reading 82%, grade A+, #265 of 1,100 statewide, top 26%, 850 students, 19% FRL) — zoned schools at 11% FRL track the district average.
- Market conditions: 133 active listings in the ZIP; high-income renter base; 824 units permitted in Nassau County in 2024 (153 in 5+ unit buildings).
- At $7,431/mo this rent would consume 65% of the median local household income ($137k/yr) (locally 618% 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 $23k 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 7 days on market — expect competitive offers; lowballing is unlikely to land.
- 4 sale attempts since 11y 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 $462k; list at $775k implies a 68% gain — meaningful room to come down on a strong offer.
Risks & watch-outs
- Watch-outs: built in 1937 — expect roof / HVAC / electrical / plumbing capex.
- Climate carrying-cost: major wind risk, 70% 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.
Questions for the listing agent
- Can we see the unit-by-unit rent roll, current vacancy, and any below-market leases? What's the average tenancy length?
- What capital expenditures (roof, boiler, parking lot, exteriors) have been made in the last 5 years, and what's planned in the next 2?
- Built in 1937 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
- Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
- Schools are A-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?
- 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.
- 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.
- 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.
