What this means for you Summary

Snapshot

• This is a 2 × 3-bed/2.5-bath units multifamily listed at $959k.

Deal economics

• At list price, monthly cash flow is $856 ($10k/yr) — positive. Per door: $428/mo.
• The deal already cash-flows at list — no discount required.
• To meet the 1% rule (rent ≥ 1% of price), the offer needs to be $915k (4.6% below list).
• Recommended offer: $915k (4.6% below list) — sets the bar for 1% rule.
• Cap rate 7.5% 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: Mamaroneck Avenue School (math 43% / reading 60%, grade C-, #1,041 of 2,108 statewide, top 50%, 684 students, 49% 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 average 31% FRL vs 12% district-wide (19 pts higher); higher-poverty schools than district average — tighter screening recommended.
• Market conditions: Rents rising fast (+6.7%/yr); 124 active listings in the ZIP; 1 comparable units currently listed for rent nearby; high-income renter base; 954 units permitted in Westchester County in 2024 (649 in 5+ unit buildings).
• At $9,151/mo this rent would consume 87% of the median local household income ($126k/yr) (locally 1152% 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 $26k 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 $245k cash investment doubles in ~10 years — after that, you're playing with house money.

Negotiation context

• Only 9 days on market — expect competitive offers; lowballing is unlikely to land.

Risks & watch-outs

• 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 $915,100 (4.6% below list)

Questions for the listing agent

1. Can we see the unit-by-unit rent roll, current vacancy, and any below-market leases? What's the average tenancy length?
2. What capital expenditures (roof, boiler, parking lot, exteriors) have been made in the last 5 years, and what's planned in the next 2?
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.
