What this means for you Summary
Snapshot
- This is a 2 × 3-bed/1.0-bath units multifamily listed at $880k.
Deal economics
- At list price, monthly cash flow is $683 ($8k/yr) — positive. Per door: $341/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 $856k (2.7% below list).
- Recommended offer: $854k (3.0% below list) — sets the bar for market timing.
- Cap rate 7.2% vs local median 4.4% in New Cassel — 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 73/100 on livability (#311 in NY) — a middle-class / working-renter tenant base. Strengths: commute A+, employment A+, housing A+; Watch: amenities D, cost of living F, health & safety D-.
- Westbury Union Free School District (suburban): math 28% / reading 43% proficiency, ranked #531 of 590 in NY (top 90%) — families likely to look elsewhere, expect single-tenant / working-renter base with shorter leases; 75% free/reduced lunch — lower-income household profile, screen leases tightly.
- Zoned schools: Park Avenue School (math 14% / reading 35%, grade F, #1,846 of 2,108 statewide, top 91%, 556 students, 61% FRL); Westbury Middle School (math 5% / reading 32%, grade F, #689 of 729 statewide, top 95%, 1,053 students, 61% FRL); Westbury High School (math 79% / reading 75%, grade A-, #583 of 1,100 statewide, top 56%, 1,541 students, 59% FRL).
- Market conditions: 183 active listings in the ZIP; high-income renter base; 824 units permitted in Nassau County in 2024 (153 in 5+ unit buildings).
- At $8,564/mo this rent would consume 67% of the median local household income ($153k/yr) (locally 730% 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 $6k of loan paydown is wiped out by about $26k 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 52 days — a 3% lower offer ($854k) is reasonable based on typical stale-listing flexibility.
- Current owner paid $235k; list at $880k implies a 274% gain — meaningful room to come down on a strong offer.
Risks & watch-outs
- Watch-outs: built in 1908 — expect roof / HVAC / electrical / plumbing capex.
- Climate carrying-cost: major wind risk, 41% 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
- It's been on market 52 days. Have you received any prior offers? Is the seller open to a 3% concession, seller financing, or rate buy-down credit?
- 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 1908 — 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 D-rated, which usually means shorter tenancies and higher turnover. Who's the typical renter profile here, and what's been the actual vacancy rate?
- 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.
