Investor read

• This is a 4-bed/1.0-bath single-family listed at $1.38M. Condition is rated good.
• At list price, monthly cash flow is $4k ($43k/yr) — positive.
• The deal already cash-flows at list — no discount required.
• Meets the 1% rule at list price ($16k rent vs $1.38M).
• It's been on market 178 days — a 12% lower offer ($1.21M) is reasonable based on typical stale-listing flexibility.
• Recommended offer: $1.21M (12.0% below list) — sets the bar for market timing.
• Local home prices are declining (-3.0%/yr); year-one equity from $10k of loan paydown is wiped out by about $41k of value loss. Plan a longer hold.
• Location reads 61/100 on livability (#943 in NY) — a middle-class / working-renter tenant base. Strengths: crime A+, employment A+; Watch: amenities F, commute F, cost of living F.
• East Quogue Union Free School District (suburban): math 55% / reading 50% proficiency, ranked #342 of 755 in NY (top 45%) — acceptable for families but not a draw, mixed tenant base, ~2y average lease; only 15% free/reduced lunch — higher-income household profile.
• Zoned schools: East Quogue School (math 57% / reading 62%, grade B-, #745 of 2,108 statewide, top 39%, 355 students, 31% FRL) — zoned schools average 31% FRL vs 15% district-wide (16 pts higher); higher-poverty schools than district average — tighter screening recommended.
• Watch-outs: flood insurance adds $427/mo.
• Market conditions: 105 active listings in the ZIP; 18 comparable units currently listed for rent nearby; rentals lingering (median 77d on market — plan ~5-8 weeks vacancy on turnover, expect pricing pressure); 67% of comp listings sitting > 30 days — soft ceiling on asking rent; solid renter incomes; 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.
• 3 sale attempts since 14y 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 $190k; list at $1.38M implies a 624% gain — meaningful room to come down on a strong offer.
• At projected returns (-3.0% appreciation + 3.0% rent growth), your $385k cash investment doubles in ~10 years — after that, you're playing with house money.
• Climate carrying-cost: in FEMA flood zone AE (mandatory federal flood insurance); severe wind risk, 80% chance of damaging wind over 30y — expect insurance premiums to compound above CPI over the hold.
• Cap rate 9.8% vs local median 6.6% in East Quogue — 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.

Questions for listing agent

• It's been on market 178 days. Have you received any prior offers? Is the seller open to a 12% concession, seller financing, or rate buy-down credit?
• What's the actual annual flood-insurance premium (NFIP or private), and is the property in a SFHA with mandatory coverage?
• What does the HOA fee cover, when was the last increase, and are there any pending special assessments or reserve-fund shortfalls?
• Why hasn't it sold? Are there any deal-killer items the seller is aware of (foundation, flood, title, zoning, code violations)?
• Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
• 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?
• 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.
