Investor read

• This is a 3-bed/2.0-bath single-family listed at $1.50M.
• At list price, monthly cash flow is $5k ($55k/yr) — positive.
• The deal already cash-flows at list — no discount required.
• Meets the 1% rule at list price ($19k rent vs $1.50M).
• Only 3 days on market — expect competitive offers; lowballing is unlikely to land.
• Local home prices are declining (-3.0%/yr); year-one equity from $10k of loan paydown is wiped out by about $45k of value loss. Plan a longer hold.
• Location reads 58/100 on livability (#1,063 in NY) — a working-class tenant base; expect higher turnover. Strengths: crime A+, employment A+; Watch: housing C-, amenities F, commute F.
• Southampton Union Free School District (suburban): math 53% / reading 51% proficiency, ranked #293 of 590 in NY (top 50%) — acceptable for families but not a draw, mixed tenant base, ~2y average lease.
• Zoned schools: Southampton Elementary School (math 42% / reading 57%, grade D, #1,085 of 2,108 statewide, top 56%, 376 students, 51% FRL); Southampton Intermediate School (math 30% / reading 47%, grade F, #437 of 729 statewide, top 60%, 363 students, 44% FRL); Southampton High School (math 98%, 595 students, 48% FRL) — zoned schools average 48% FRL vs 30% district-wide (17 pts higher); higher-poverty schools than district average — tighter screening recommended.
• Market conditions: Rents rising fast (+14.6%/yr); 95 active listings in the ZIP; 5 comparable units currently listed for rent nearby; rentals lingering (median 44d on market — plan ~5-8 weeks vacancy on turnover, expect pricing pressure); 60% 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).
• Suffolk County population projected to shrink 5% by 2050 — rents likely to lag national; underwrite the cash flow, not the appreciation.
• 4 sale attempts since 9y 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 $410k; list at $1.50M implies a 265% gain — meaningful room to come down on a strong offer.
• At projected returns (-3.0% appreciation + 8.0% rent growth), your $419k cash investment doubles in ~7 years — after that, you're playing with house money.
• Climate carrying-cost: major flood risk; severe wind risk, 80% chance of damaging wind over 30y — expect insurance premiums to compound above CPI over the hold.
• Cap rate 10.0% vs local median 6.5% in North Sea — 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.
• At $18,873/mo this rent would consume 145% of the median local household income ($156k/yr) (locally 274% of renters already pay >50% of income on rent) — very limited rent-growth headroom before tenants either downsize or default.

Questions for listing agent

• Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
• 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?
• 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.
• 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.
• 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.
