What this means for you Summary
Snapshot
- This is a 2 × 3-bed/1.5-bath units multifamily listed at $560k.
Deal economics
- At list price, monthly cash flow is $935 ($11k/yr) — positive. Per door: $467/mo.
- The deal already cash-flows at list — no discount required.
- Meets the 1% rule at list price ($7k rent vs $560k).
- Recommended offer: $543k (3.0% below list) — sets the bar for market timing.
- Cap rate 8.3% vs local median 5.2% in Mount Vernon — 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 71/100 on livability (#397 in NY) — a middle-class / working-renter tenant base. Strengths: commute A+, health & safety A, employment B; Watch: crime D-, cost of living F.
- Mount Vernon School District (suburban): math 35% / reading 50% proficiency, ranked #485 of 590 in NY (top 82%) — families likely to look elsewhere, expect single-tenant / working-renter base with shorter leases; 62% free/reduced lunch — lower-income household profile, screen leases tightly.
- Market conditions: Rents rising (+3.4%/yr); 130 active listings in the ZIP; 5 comparable units currently listed for rent nearby; rentals at typical pace (median 25d on market — plan ~3-4 weeks tenant-placement turnaround); 954 units permitted in Westchester County in 2024 (649 in 5+ unit buildings).
- At $6,972/mo this rent would consume 138% of the median local household income ($61k/yr) (locally 2963% 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 $17k of value loss. Plan a longer hold.
- Westchester County population projected at +10% by 2050 — modest demand growth; plan on rents tracking national, not racing it.
Negotiation context
- It's been on market 38 days — a 3% lower offer ($543k) is reasonable based on typical stale-listing flexibility.
- 6 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: property tax is 3.0% of price; built in 1920 — expect roof / HVAC / electrical / plumbing capex.
- Climate carrying-cost: major wind risk, 27% chance of damaging wind over 30y; extreme-heat days projected 7→15/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 38 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 1920 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
- Property tax is high relative to price — has the assessment been appealed recently, and will the sale trigger a re-assessment?
- Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
- Crime grade is D in this area — have there been break-ins, vandalism, or insurance claims at this property in the last 3 years? What carrier currently insures it and at what premium?
- 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.
