What this means for you Summary

Snapshot

  • This is a 4-bed/3.0-bath single-family listed at $1.90M. Condition is rated good.

Deal economics

  • At list price, monthly cash flow is $7k ($87k/yr) — positive.
  • The deal already cash-flows at list — no discount required.
  • Meets the 1% rule at list price ($24k rent vs $1.90M).
  • Recommended offer: $1.67M (12.0% below list) — sets the bar for market timing.
  • Cap rate 10.9% vs local median 7.8% in Northwest Harbor — 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 60/100 on livability (#1,007 in NY) — a middle-class / working-renter tenant base. Strengths: crime A+, employment A+; Watch: amenities F, commute F, cost of living F.
  • East Hampton Union Free School District (town): math 62% / reading 66% proficiency, ranked #159 of 590 in NY (top 27%) — acceptable for families but not a draw, mixed tenant base, ~2y average lease.
  • Zoned schools: John M Marshall Elementary School (math 57% / reading 62%, grade B-, #745 of 2,108 statewide, top 39%, 548 students, 51% FRL); East Hampton Middle School (math 39% / reading 60%, grade C, #280 of 729 statewide, top 40%, 265 students, 42% FRL); East Hampton High School (math 94% / reading 98%, grade A+, #71 of 1,100 statewide, top 7%, 1,015 students, 40% FRL) — zoned schools average 44% FRL vs 26% district-wide (18 pts higher); higher-poverty schools than district average — tighter screening recommended.
  • Market conditions: Rents rising fast (+12.3%/yr); 172 active listings in the ZIP; 6 comparable units currently listed for rent nearby; rentals lingering (median 93d on market — plan ~5-8 weeks vacancy on turnover, expect pricing pressure); 100% of comp listings sitting > 30 days — soft ceiling on asking rent; high-income renter base; 1,366 units permitted in Suffolk County in 2024 (216 in 5+ unit buildings).
  • At $23,805/mo this rent would consume 220% of the median local household income ($130k/yr) — 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 $13k of loan paydown is wiped out by about $57k 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 (-3.0% appreciation + 8.0% rent growth), your $532k cash investment doubles in ~6 years — after that, you're playing with house money.

Negotiation context

  • It's been on market 122 days — a 12% lower offer ($1.67M) is reasonable based on typical stale-listing flexibility.
  • 4 sale attempts since 12y ago; this cycle's ask has dropped $100k (5%) from the opening price — seller is motivated, your offer sets the floor, not the list.
  • Current owner paid $60k; list at $1.90M implies a 3067% gain — meaningful room to come down on a strong offer.

Risks & watch-outs

  • 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 $1,671,999 (12.0% below list)

Questions for the listing agent

  1. It's been on market 122 days. Have you received any prior offers? Is the seller open to a 12% concession, seller financing, or rate buy-down credit?
  2. Why hasn't it sold? Are there any deal-killer items the seller is aware of (foundation, flood, title, zoning, code violations)?
  3. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
  4. Schools are D-rated, which usually means shorter tenancies and higher turnover. Who's the typical renter profile here, and what's been the actual vacancy rate?
  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 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.
