What this means for you Summary

Snapshot

• This is a 1-bed/1.0-bath condo listed at $255k.

Deal economics

• At list price, monthly cash flow is $725 ($9k/yr) — positive.
• The deal already cash-flows at list — no discount required.
• Meets the 1% rule at list price ($3k rent vs $255k).
• Cap rate 9.7% vs local median 3.1% in Mamaroneck — 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 69/100 on livability (#491 in NY) — a middle-class / working-renter tenant base. Strengths: crime A+, employment A+; Watch: amenities C-, commute F, cost of living F.
• Mamaroneck Union Free School District (suburban): math 74% / reading 81% proficiency, ranked #47 of 590 in NY (top 8%) — strong family-tenant draw, lease renewals of 3-5y typical; only 12% free/reduced lunch — higher-income household profile.
• Zoned schools: Murray Avenue School (math 88% / reading 90%, grade A+, #61 of 2,108 statewide, top 3%, 703 students, 2% FRL); Hommocks School (math 65% / reading 79%, grade A, #76 of 729 statewide, top 11%, 1,258 students, 20% FRL); Mamaroneck High School (math 95% / reading 91%, grade A+, #147 of 1,100 statewide, top 14%, 1,660 students, 23% FRL) — zoned schools at 15% FRL track the district average.
• Market conditions: Rents rising fast (+6.7%/yr); 126 active listings in the ZIP; 16 comparable units currently listed for rent nearby; rentals lingering (median 45d on market — plan ~5-8 weeks vacancy on turnover, expect pricing pressure); 56% of comp listings sitting > 30 days — soft ceiling on asking rent; high-income renter base; 954 units permitted in Westchester County in 2024 (649 in 5+ unit buildings).

Forward outlook

• Local home prices are declining (-3.0%/yr); year-one equity from $2k of loan paydown is wiped out by about $8k 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 + 6.7% rent growth), your $71k cash investment doubles in ~7 years — after that, you're playing with house money.

Negotiation context

• Only 12 days on market — expect competitive offers; lowballing is unlikely to land.
• 2 sale attempts since 24y ago; this cycle's ask is 38% above the opening price — seller raised mid-cycle; expect resistance to lowballs.
• Current owner paid $176k; 45% above their basis — modest negotiation headroom, anchor on the comps not their cost.

Risks & watch-outs

• Watch-outs: built in 1927 — expect roof / HVAC / electrical / plumbing capex.
• Climate carrying-cost: major wind risk, 27% 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.

Recommended offer $255,000

Questions for the listing agent

1. Built in 1927 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
2. 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?
3. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
4. Schools are B-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?
5. 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.
6. 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.
7. 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.
