Investor read

• This is a 3-bed/1.0-bath single-family listed at $399k.
• At list price, monthly cash flow is $183 ($2k/yr) — positive.
• The deal already cash-flows at list — no discount required.
• Meets the 1% rule at list price ($4k rent vs $399k).
• Only 9 days on market — expect competitive offers; lowballing is unlikely to land.
• Local home prices are declining (-3.0%/yr); year-one equity from $3k of loan paydown is wiped out by about $12k of value loss. Plan a longer hold.
• Location reads 66/100 on livability (#658 in NY) — a middle-class / working-renter tenant base. Strengths: employment A+, housing A+; Watch: amenities F, commute F, cost of living F.
• Sachem Central School District (suburban): math 69% / reading 76% proficiency, ranked #86 of 590 in NY (top 15%) — strong family-tenant draw, lease renewals of 3-5y typical; only 15% free/reduced lunch — higher-income household profile.
• Zoned schools: Chippewa Elementary School (math 47% / reading 62%, grade C, #908 of 2,108 statewide, top 46%, 515 students, 25% FRL); Samoset Middle School (math 51% / reading 63%, grade B, #192 of 729 statewide, top 28%, 892 students, 31% FRL); Sachem High School North (math 96% / reading 95%, grade A+, #76 of 1,100 statewide, top 7%, 1,923 students, 25% FRL).
• Watch-outs: built in 1953 — expect roof / HVAC / electrical / plumbing capex.
• Market conditions: Rents flat; 175 active listings in the ZIP; 2 comparable units currently listed for rent nearby; 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.
• Climate carrying-cost: major flood risk; major wind risk, 77% chance of damaging wind over 30y — expect insurance premiums to compound above CPI over the hold.
• Cap rate 6.8% vs local median 3.5% in Holbrook — 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.
• This rent runs 44% of the median local income ($112k/yr) — at the standard rent-burdened threshold; future hikes will face affordability resistance.

Questions for listing agent

• Built in 1953 — 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.
• 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.
