What this means for you Summary

Snapshot

• This is a 3 × 5-bed/3.0-bath units multifamily listed at $820k.

Deal economics

• At list price, monthly cash flow is $5k ($56k/yr) — positive. Per door: $2k/mo.
• The deal already cash-flows at list — no discount required.
• Meets the 1% rule at list price ($13k rent vs $820k).
• Recommended offer: $722k (12.0% below list) — sets the bar for market timing.
• Cap rate 13.1% vs local median 5.3% 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; 954 units permitted in Westchester County in 2024 (649 in 5+ unit buildings).
• At $12,639/mo this rent would consume 250% 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 $6k of loan paydown is wiped out by about $25k 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.
• At projected returns (-3.0% appreciation + 3.4% rent growth), your $230k cash investment doubles in ~5 years — after that, you're playing with house money.

Negotiation context

• It's been on market 188 days — a 12% lower offer ($722k) is reasonable based on typical stale-listing flexibility.
• Current owner paid $195k; list at $820k implies a 321% gain — meaningful room to come down on a strong offer.

Risks & watch-outs

• Watch-outs: built in 1938 — 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.

Recommended offer $721,600 (12.0% below list)

Questions for the listing agent

1. It's been on market 188 days. Have you received any prior offers? Is the seller open to a 12% concession, seller financing, or rate buy-down credit?
2. Can we see the unit-by-unit rent roll, current vacancy, and any below-market leases? What's the average tenancy length?
3. What capital expenditures (roof, boiler, parking lot, exteriors) have been made in the last 5 years, and what's planned in the next 2?
4. Built in 1938 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
5. Why hasn't it sold? Are there any deal-killer items the seller is aware of (foundation, flood, title, zoning, code violations)?
6. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
7. 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?
8. 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.
9. 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.
10. 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.
