Investor read

• This is a 4-bed/4.5-bath single-family listed at $1.90M.
• At list price, monthly cash flow is $-2k ($-20k/yr) — negative.
• To cash-flow at today's rent, offer at most $1.60M (15.6% below list).
• To meet the 1% rule (rent ≥ 1% of price), the offer needs to be $1.37M (28.0% below list).
• Only 12 days on market — expect competitive offers; lowballing is unlikely to land.
• Recommended offer: $1.37M (28.0% below list) — sets the bar for 1% rule.
• In year one you build about $115k of equity ($13k loan paydown + $102k appreciation (5.4% local appreciation)).
• Location reads 82/100 on livability (#78 in NY, #1,199 nationally) — a professional / high-income tenant draw. Strengths: crime A+, commute A+, employment A+; Watch: amenities C-, cost of living F.
• Manhasset Union Free School District (suburban): math 86% / reading 84% proficiency, ranked #8 of 590 in NY (top 1%) — strong family-tenant draw, lease renewals of 3-5y typical; only 4% free/reduced lunch — higher-income household profile.
• Zoned schools: Munsey Park Elementary School (math 82% / reading 87%, grade A+, #93 of 2,108 statewide, top 6%, 863 students, 7% FRL); Manhasset Middle School (math 84% / reading 79%, grade A+, #22 of 729 statewide, top 3%, 521 students, 6% FRL); Manhasset Secondary School (math 100% / reading 87%, grade A+, #141 of 1,100 statewide, top 13%, 962 students, 8% FRL) — zoned schools at 7% FRL track the district average.
• Watch-outs: built in 1928 — expect roof / HVAC / electrical / plumbing capex.
• Market conditions: 118 active listings in the ZIP; 3 comparable units currently listed for rent nearby; rentals leasing fast (median 7d on market — plan ~1-2 weeks tenant-placement turnaround); 824 units permitted in Nassau County in 2024 (153 in 5+ unit buildings).
• Nassau County population projected at +7% by 2050 — modest demand growth; plan on rents tracking national, not racing it.
• Current owner paid $350k; list at $1.90M implies a 443% gain — meaningful room to come down on a strong offer.
• By year 2, paydown + projected appreciation supports a ~$185k cash-out refi (75% LTV) — recoverable capital for the next deal without selling this one.
• Climate carrying-cost: major wind risk, 27% chance of damaging wind over 30y; extreme-heat days projected 7→16/yr by 2055 (HVAC capex compounding) — expect insurance premiums to compound above CPI over the hold.
• Cap rate 5.2% vs local median 2.2% in Manhasset — 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

• 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?
• Built in 1928 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
• Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
• 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?
• 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.
