What this means for you Summary

Snapshot

• This is a 2-bed/2.0-bath condo listed at $429k.

Deal economics

• At list price, monthly cash flow is $-114 ($-1k/yr) — negative.
• To cash-flow at today's rent, offer at most $413k (3.8% below list).
• To meet the 1% rule (rent ≥ 1% of price), the offer needs to be $361k (15.9% below list).
• Recommended offer: $361k (15.9% below list) — sets the bar for 1% rule.
• Cap rate 6.0% 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: Central School (math 78% / reading 78%, grade A, #239 of 2,108 statewide, top 11%, 513 students, 14% 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).
• Market conditions: Rents rising fast (+6.7%/yr); 126 active listings in the ZIP; 17 comparable units currently listed for rent nearby; rentals at typical pace (median 26d on market — plan ~3-4 weeks tenant-placement turnaround); 41% 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).
• This rent runs 34% of the median local income ($126k/yr) — at the standard rent-burdened threshold; future hikes will face affordability resistance.

Forward outlook

• Local home prices are declining (-3.0%/yr); year-one equity from $3k of loan paydown is wiped out by about $13k 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 26 days — a 2% lower offer ($423k) is reasonable based on typical stale-listing flexibility.
• 3 sale attempts since 4y ago 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.
• Current owner paid $250k; list at $429k implies a 72% gain — meaningful room to come down on a strong offer.

Risks & watch-outs

• Climate carrying-cost: major wind risk, 27% chance of damaging wind over 30y; extreme-heat days projected 7→17/yr by 2055 (HVAC capex compounding) — expect insurance premiums to compound above CPI over the hold.

Recommended offer $360,895 (15.9% below list)

Questions for the listing agent

1. What do current leases actually rent for vs. the listed asking? Can we see a recent rent roll and the last 12 months of T-12 income?
2. Built in 1962 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
3. 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?
4. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
5. 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?
6. The area grade is low — what's the realistic commute time and amenity access for the typical tenant pool here? Any planned neighborhood developments (good or bad) we should know about?
7. 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.
8. 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.
9. 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.
