What this means for you Summary

Snapshot

  • This is a 4-bed/2.0-bath single-family listed at $1.99M.

Deal economics

  • At list price, monthly cash flow is $-6k ($-71k/yr) — negative.
  • To cash-flow at today's rent, offer at most $945k (52.4% below list).
  • To meet the 1% rule (rent ≥ 1% of price), the offer needs to be $826k (58.4% below list).
  • Recommended offer: $826k (58.4% below list) — sets the bar for 1% rule.
  • Cap rate 2.7% vs local median 4.6% in Roslyn — below-typical yield; the buyer is paying a premium for something (appreciation thesis, condition, location) that the cap rate doesn't capture.

Location & tenants

  • Location reads 83/100 on livability (#63 in NY, #910 nationally) — a professional / high-income tenant draw. Strengths: crime A+, commute A+, employment A+; Watch: cost of living F.
  • Roslyn Union Free School District (suburban): math 83% / reading 82% proficiency, ranked #28 of 590 in NY (top 5%) — strong family-tenant draw, lease renewals of 3-5y typical; only 8% free/reduced lunch — higher-income household profile.
  • Zoned schools: Roslyn Heights Elementary School (345 students, 20% FRL); Roslyn Middle School (math 78% / reading 82%, grade A+, #28 of 729 statewide, top 4%, 766 students, 16% FRL); Roslyn High School (math 97% / reading 87%, grade A+, #171 of 1,100 statewide, top 18%, 1,035 students, 15% FRL).
  • Market conditions: 81 active listings in the ZIP; 2 comparable units currently listed for rent nearby; 824 units permitted in Nassau County in 2024 (153 in 5+ unit buildings).

Forward outlook

  • In year one you build about $162k of equity ($14k loan paydown + $149k appreciation (7.5% local appreciation)).
  • Nassau County population projected at +7% by 2050 — modest demand growth; plan on rents tracking national, not racing it.
  • By year 2, paydown + projected appreciation supports a ~$260k cash-out refi (75% LTV) — recoverable capital for the next deal without selling this one.

Negotiation context

  • Only 8 days on market — expect competitive offers; lowballing is unlikely to land.
  • Current owner paid $490k; list at $1.99M implies a 305% gain — meaningful room to come down on a strong offer.

Risks & watch-outs

  • Watch-outs: built in 1943 — expect roof / HVAC / electrical / plumbing capex.
  • Climate carrying-cost: major wind risk, 52% 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.
Recommended offer $826,057 (58.4% 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 1943 — 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. 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?
  5. 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.
  6. 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.
  7. 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.
