Investor read

• This is a 1-bed/1.0-bath condo listed at $189k. Condition is rated good.
• At list price, monthly cash flow is $566 ($7k/yr) — positive.
• The deal already cash-flows at list — no discount required.
• Meets the 1% rule at list price ($2k rent vs $189k).
• Only 12 days on market — expect competitive offers; lowballing is unlikely to land.
• Local home prices are declining (-3.0%/yr); year-one equity from $1k of loan paydown is wiped out by about $6k of value loss. Plan a longer hold.
• 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.
• Zoned schools: Pennington School (math 42% / reading 62%, grade C-, #988 of 2,108 statewide, top 49%, 426 students, 45% FRL); Mount Vernon High School (math 54% / reading 75%, grade B-, #776 of 1,100 statewide, top 73%, 1,094 students, 76% FRL) — zoned schools at 60% FRL track the district average.
• Zoned-school proficiency averages 58% at this address vs 42% district-wide (+16 pts) — the actual schools serving this property are materially stronger than the Mount Vernon School District average implies; a family-tenant draw the district grade alone would hide.
• Watch-outs: built in 1939 — expect roof / HVAC / electrical / plumbing capex.
• Market conditions: Rents rising fast (+7.0%/yr); 128 active listings in the ZIP; 37 comparable units currently listed for rent nearby; rentals at typical pace (median 26d on market — plan ~3-4 weeks tenant-placement turnaround); solid renter incomes; 954 units permitted in Westchester County in 2024 (649 in 5+ unit buildings).
• 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 + 7.0% rent growth), your $53k cash investment doubles in ~7 years — after that, you're playing with house money.
• 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.
• Cap rate 9.9% 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.

Questions for listing agent

• Built in 1939 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
• 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?
• 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.
