What this means for you Summary

Snapshot

• This is a 3-bed/1.0-bath single-family listed at $429k.

Deal economics

• At list price, monthly cash flow is $-66 ($-797/yr) — negative.
• To cash-flow at today's rent, offer at most $417k (2.7% below list).
• To meet the 1% rule (rent ≥ 1% of price), the offer needs to be $357k (16.7% below list).
• Recommended offer: $357k (16.7% below list) — sets the bar for 1% rule.
• Cap rate 6.1% vs local median 4.7% in Mastic Beach — meaningfully above typical; check what's discounted (condition, days-on-market, listing class) to confirm the premium yield is real.

Location & tenants

• 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: Tangier Smith Elementary School (math 43% / reading 54%, grade D, #1,181 of 2,108 statewide, top 56%, 755 students, 61% FRL); William Paca Middle School (math 31% / reading 37%, grade F, #497 of 729 statewide, top 69%, 1,009 students, 59% FRL); William Floyd High School (math 65% / reading 87%, grade A-, #616 of 1,100 statewide, top 57%, 3,013 students, 54% FRL) — zoned schools average 58% FRL vs 43% district-wide (15 pts higher); higher-poverty schools than district average — tighter screening recommended.
• Market conditions: 135 active listings in the ZIP; 3 comparable units currently listed for rent nearby; rentals at typical pace (median 26d on market — plan ~3-4 weeks tenant-placement turnaround); 1,366 units permitted in Suffolk County in 2024 (216 in 5+ unit buildings).

Forward outlook

• In year one you build about $46k of equity ($3k loan paydown + $43k appreciation (10.0% local appreciation)).
• Suffolk County population projected to shrink 5% by 2050 — rents likely to lag national; underwrite the cash flow, not the appreciation.
• At projected returns (10.0% appreciation + 3.0% rent growth), your $120k cash investment doubles in ~3 years — after that, you're playing with house money.
• By year 2, paydown + projected appreciation supports a ~$74k cash-out refi (75% LTV) — recoverable capital for the next deal without selling this one.

Negotiation context

• Only 12 days on market — expect competitive offers; lowballing is unlikely to land.

Risks & watch-outs

• Climate carrying-cost: severe wind risk, 80% chance of damaging wind over 30y — expect insurance premiums to compound above CPI over the hold.

Recommended offer $357,249 (16.7% below list)

Questions for the listing agent

1. 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?
2. Built in 1976 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
3. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
4. 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?
5. 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?
6. 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.
7. 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.
8. 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.

For passive investors: Depreciation is non-cash, so a rental often shows a tax loss while cash-flowing — sheltering income. Rental losses are passive: they offset passive income freely, and up to $25,000/yr can offset ordinary (W-2) income if you actively participate and your MAGI is under $100k (phasing out to $0 by $150k); unused losses carry forward. On sale, claimed depreciation is recaptured at up to 25%, and gains may owe capital-gains tax (a 1031 exchange can defer both). Figures are a year-1 estimate at your 24.0% rate — not tax advice; consult a CPA.
