What this means for you Summary

Snapshot

  • This is a 3-bed/2.0-bath single-family listed at $1.50M.

Deal economics

  • At list price, monthly cash flow is $8k ($101k/yr) — positive.
  • The deal already cash-flows at list — no discount required.
  • Meets the 1% rule at list price ($24k rent vs $1.50M).

Location & tenants

  • Location reads 70/100 on livability (#427 in NY) — a middle-class / working-renter tenant base. Strengths: crime A+, employment A+, health & safety A; Watch: amenities F, commute F, cost of living F.
  • Sag Harbor Union Free School District (suburban): math 54% / reading 70% proficiency, ranked #175 of 590 in NY (top 30%) — acceptable for families but not a draw, mixed tenant base, ~2y average lease; only 8% free/reduced lunch — higher-income household profile.
  • Zoned schools: Sag Harbor Elementary School (math 47% / reading 72%, grade B-, #745 of 2,108 statewide, top 39%, 426 students, 22% FRL); Pierson Middle/High School (math 61% / reading 72%, grade B, #763 of 1,100 statewide, top 69%, 525 students, 25% FRL) — zoned schools average 24% FRL vs 8% district-wide (16 pts higher); higher-poverty schools than district average — tighter screening recommended.
  • Market conditions: Rents rising fast (+10.8%/yr); 65 active listings in the ZIP; 6 comparable units currently listed for rent nearby; rentals at typical pace (median 23d on market — plan ~3-4 weeks tenant-placement turnaround); high-income renter base; 1,366 units permitted in Suffolk County in 2024 (216 in 5+ unit buildings).
  • At $23,685/mo this rent would consume 222% of the median local household income ($128k/yr) (locally 95% of renters already pay >50% of income on rent) — very limited rent-growth headroom before tenants either downsize or default.

Forward outlook

  • In year one you build about $148k of equity ($10k loan paydown + $137k appreciation (9.2% local appreciation)).
  • Suffolk County population projected to shrink 5% by 2050 — rents likely to lag national; underwrite the cash flow, not the appreciation.
  • At projected returns (9.2% appreciation + 8.0% rent growth), your $419k cash investment doubles in ~2 years — after that, you're playing with house money.
  • By year 2, paydown + projected appreciation supports a ~$237k cash-out refi (75% LTV) — recoverable capital for the next deal without selling this one.

Negotiation context

  • Only 14 days on market — expect competitive offers; lowballing is unlikely to land.
  • 3 sale attempts; this cycle's ask has dropped $230k (13%) from the opening price — seller is motivated, your offer sets the floor, not the list.

Risks & watch-outs

  • Climate carrying-cost: severe wind risk, 80% chance of damaging wind over 30y; extreme-heat days projected 7→20/yr by 2055 (HVAC capex compounding) — expect insurance premiums to compound above CPI over the hold.
Recommended offer $1,495,000

Questions for the listing agent

  1. Built in 1970 — 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. Schools are A-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?
  4. 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.
  5. 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.
  6. 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.
