What this means for you Summary

Snapshot

• This is a 4-bed/5.5-bath land listed at $2.19M.

Deal economics

• At list price, monthly cash flow is $2k ($28k/yr) — positive.
• The deal already cash-flows at list — no discount required.
• Meets the 1% rule at list price ($22k rent vs $2.19M).
• Recommended offer: $1.93M (12.0% below list) — sets the bar for market timing.

Location & tenants

• Location reads 67/100 on livability (#583 in NY) — a middle-class / working-renter tenant base. Strengths: crime A+, employment A+, schools A-; Watch: amenities F, commute F, cost of living F.
• Southold Union Free School District (town): math 46% / reading 59% proficiency, ranked #298 of 590 in NY (top 50%) — acceptable for families but not a draw, mixed tenant base, ~2y average lease; only 17% free/reduced lunch — higher-income household profile.
• Market conditions: 79 active listings in the ZIP; 4 comparable units currently listed for rent nearby; rentals lingering (median 44d 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 $15k of loan paydown is wiped out by about $66k 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.

Negotiation context

• It's been on market 372 days — a 12% lower offer ($1.93M) is reasonable based on typical stale-listing flexibility.
• 2 sale attempts; this cycle's ask is 10% above the opening price — seller raised mid-cycle; expect resistance to lowballs.
• Current owner paid $625k; list at $2.19M implies a 251% gain — meaningful room to come down on a strong offer.

Risks & watch-outs

• Watch-outs: flood insurance adds $66/mo.
• Climate carrying-cost: severe flood risk; severe wind risk, 80% chance of damaging wind over 30y; extreme-heat days projected 7→19/yr by 2055 (HVAC capex compounding) — expect insurance premiums to compound above CPI over the hold.

Recommended offer $1,931,600 (12.0% below list)

Questions for the listing agent

1. It's been on market 372 days. Have you received any prior offers? Is the seller open to a 12% concession, seller financing, or rate buy-down credit?
2. What's the actual annual flood-insurance premium (NFIP or private), and is the property in a SFHA with mandatory coverage?
3. Why hasn't it sold? Are there any deal-killer items the seller is aware of (foundation, flood, title, zoning, code violations)?
4. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
5. 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?
6. 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?
7. 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.
8. 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.
9. 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.
