Investor read

• This is a 3-bed/2.0-bath single-family listed at $450k.
• At list price, monthly cash flow is $-785 ($-9k/yr) — negative.
• To cash-flow at today's rent, offer at most $311k (30.8% below list).
• To meet the 1% rule (rent ≥ 1% of price), the offer needs to be $348k (22.7% below list).
• It's been on market 35 days — a 3% lower offer ($436k) is reasonable based on typical stale-listing flexibility.
• Recommended offer: $311k (30.8% below list) — sets the bar for cash-flow.
• In year one you build about $48k of equity ($3k loan paydown + $45k appreciation (10.0% local appreciation)).
• Location reads 61/100 on livability (#936 in NY) — a middle-class / working-renter tenant base. Strengths: employment A+, housing A+; Watch: crime D, amenities F, commute F.
• William Floyd Union Free School District (suburban): math 48% / reading 57% proficiency, ranked #309 of 590 in NY (top 52%) — acceptable for families but not a draw, mixed tenant base, ~2y average lease.
• Zoned schools: William Floyd Elementary School (math 48% / reading 54%, grade C-, #1,047 of 2,108 statewide, top 50%, 742 students, 54% FRL); William Floyd Middle School (math 36% / reading 47%, grade F, #394 of 729 statewide, top 55%, 1,053 students, 54% FRL); William Floyd High School (math 65% / reading 87%, grade A-, #616 of 1,100 statewide, top 57%, 3,013 students, 54% FRL).
• Watch-outs: flood insurance adds $460/mo.
• Market conditions: 135 active listings in the ZIP; 6 comparable units currently listed for rent nearby; rentals at typical pace (median 18d on market — plan ~3-4 weeks tenant-placement turnaround); 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.
• 6 sale attempts since 10y 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 $330k; 36% above their basis — modest negotiation headroom, anchor on the comps not their cost.
• By year 2, paydown + projected appreciation supports a ~$77k cash-out refi (75% LTV) — recoverable capital for the next deal without selling this one.
• 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.

Questions for listing agent

• What do current leases actually rent for vs. the listed asking? Can we see a recent rent roll and the last 12 months of T-12 income?
• It's been on market 35 days. Have you received any prior offers? Is the seller open to a 31% 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?
• 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?
• Crime grade is D in this area — have there been break-ins, vandalism, or insurance claims at this property in the last 3 years? What carrier currently insures it and at what premium?
• The area grade is low — what's the realistic commute time and amenity access for the typical tenant pool here? Any planned neighborhood developments (good or bad) we should know about?
• 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.
