What this means for you Summary
Snapshot
- This is a 2-bed/1.0-bath condo listed at $195k.
Deal economics
- At list price, monthly cash flow is $1k ($14k/yr) — positive.
- The deal already cash-flows at list — no discount required.
- Meets the 1% rule at list price ($3k rent vs $195k).
- Recommended offer: $183k (6.0% below list) — sets the bar for market timing.
- Cap rate 13.7% vs local median 3.2% in Islip — 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.
Location & tenants
- Location reads 83/100 on livability (#59 in NY, #878 nationally) — a professional / high-income tenant draw. Strengths: commute A+, employment A+, housing A+; Watch: cost of living F.
- Islip Union Free School District (suburban): math 52% / reading 67% proficiency, ranked #186 of 590 in NY (top 32%) — acceptable for families but not a draw, mixed tenant base, ~2y average lease; only 20% free/reduced lunch — higher-income household profile.
- Zoned schools: Maud S Sherwood Elementary School (math 42% / reading 72%, grade C+, #842 of 2,108 statewide, top 43%, 335 students, 32% FRL); Islip Middle School (math 32% / reading 52%, grade D-, #379 of 729 statewide, top 54%, 641 students, 37% FRL); Islip High School (math 88% / reading 93%, grade A+, #231 of 1,100 statewide, top 21%, 892 students, 33% FRL).
- Market conditions: 87 active listings in the ZIP; 6 comparable units currently listed for rent nearby; rentals lingering (median 45d on market — plan ~5-8 weeks vacancy on turnover, expect pricing pressure); 50% of comp listings sitting > 30 days — soft ceiling on asking rent; 1,366 units permitted in Suffolk County in 2024 (216 in 5+ unit buildings).
Forward outlook
- Local home prices are declining (-3.0%/yr); year-one equity from $1k of loan paydown is wiped out by about $6k of value loss. Plan a longer hold.
- Suffolk County population projected to shrink 5% by 2050 — rents likely to lag national; underwrite the cash flow, not the appreciation.
- At projected returns (-3.0% appreciation + 3.0% rent growth), your $55k cash investment doubles in ~5 years — after that, you're playing with house money.
Negotiation context
- It's been on market 90 days — a 6% lower offer ($183k) is reasonable based on typical stale-listing flexibility.
Risks & watch-outs
- Climate carrying-cost: major wind risk, 64% chance of damaging wind over 30y; extreme-heat days projected 7→17/yr by 2055 (HVAC capex compounding) — expect insurance premiums to compound above CPI over the hold.
Questions for the listing agent
- It's been on market 90 days. Have you received any prior offers? Is the seller open to a 6% concession, seller financing, or rate buy-down credit?
- Built in 1970 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
- Any open or pending special assessments — roof, HVAC, plumbing, elevator, façade? What's the per-unit balance and payoff schedule, and is the seller paying it off at close or rolling it to the buyer?
- 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.
- How much new apartment / multifamily construction is in the pipeline within 1–3 miles? Heavy new supply (>2% of stock underway) typically softens rents 12–24 months out; light construction supports rent growth.

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.
