What this means for you Summary

Snapshot

• This is a 3-bed/1.5-bath single-family listed at $1.50M.

Deal economics

• At list price, monthly cash flow is $5k ($56k/yr) — positive.
• The deal already cash-flows at list — no discount required.
• Meets the 1% rule at list price ($19k rent vs $1.50M).
• Cap rate 10.0% vs local median 7.9% in Montauk — meaningfully above typical; check what's discounted (condition, days-on-market, listing class) to confirm the premium yield is real.

Location & tenants

• Location reads 69/100 on livability (#474 in NY) — a middle-class / working-renter tenant base. Strengths: crime A+, employment A+, health & safety A; Watch: housing C-, amenities F, commute F.
• Montauk Union Free School District (town): math 50% / reading 60% proficiency, ranked #311 of 755 in NY (top 41%) — acceptable for families but not a draw, mixed tenant base, ~2y average lease.
• Zoned schools: Montauk School (math 62% / reading 82%, grade A-, #378 of 2,108 statewide, top 20%, 303 students, 0% FRL) — zoned schools average 0% FRL vs 21% district-wide (21 pts lower); this property's tenant base skews higher-income than the district average.
• Zoned-school proficiency averages 72% at this address vs 55% district-wide (+17 pts) — the actual schools serving this property are materially stronger than the Montauk Union Free School District average implies; a family-tenant draw the district grade alone would hide.
• Market conditions: 39 active listings in the ZIP; high-income renter base; 1,366 units permitted in Suffolk County in 2024 (216 in 5+ unit buildings).
• At $19,019/mo this rent would consume 160% of the median local household income ($143k/yr) (locally 20% 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 (-1.8%/yr); year-one equity from $10k of loan paydown is wiped out by about $27k of value loss. Plan a longer hold.
• Suffolk County population projected to shrink 5% by 2050 — rents likely to lag national; underwrite the cash flow, not the appreciation.
• At projected returns (-1.8% appreciation + 3.0% rent growth), your $420k cash investment doubles in ~8 years — after that, you're playing with house money.

Negotiation context

• Only 1 days on market — expect competitive offers; lowballing is unlikely to land.

Risks & watch-outs

• Watch-outs: built in 1956 — expect roof / HVAC / electrical / plumbing capex.
• Climate carrying-cost: severe wind risk, 80% chance of damaging wind over 30y — expect insurance premiums to compound above CPI over the hold.

Recommended offer $1,500,000

Questions for the listing agent

1. Built in 1956 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
2. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
3. 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.
4. 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.
5. How much new for-sale + rental construction is in the pipeline within 1–3 miles? Heavy new supply typically softens prices + rents 12–24 months out; constrained supply supports both.

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.
