What this means for you Summary

Snapshot

• This is a 1-bed/1.0-bath condo listed at $375k.

Deal economics

• At list price, monthly cash flow is $-1k ($-12k/yr) — negative.
• To cash-flow at today's rent, offer at most $349k (7.0% below list).
• To meet the 1% rule (rent ≥ 1% of price), the offer needs to be $305k (18.6% below list).
• Recommended offer: $305k (18.6% below list) — sets the bar for 1% rule.
• Cap rate 3.0% vs local median 2.5% in Rockville Centre — meaningfully above typical; check what's discounted (condition, days-on-market, listing class) to confirm the premium yield is real.

Location & tenants

• Location reads 86/100 on livability (#17 in NY, #365 nationally) — a professional / high-income tenant draw. Strengths: schools A+, amenities A+, commute A+; Watch: cost of living F.
• Rockville Centre Union Free School District (suburban): math 82% / reading 82% proficiency, ranked #37 of 590 in NY (top 6%) — strong family-tenant draw, lease renewals of 3-5y typical; only 9% free/reduced lunch — higher-income household profile.
• Market conditions: 143 active listings in the ZIP; 13 comparable units currently listed for rent nearby; rentals at typical pace (median 25d on market — plan ~3-4 weeks tenant-placement turnaround); high-income renter base; 824 units permitted in Nassau County in 2024 (153 in 5+ unit buildings).

Forward outlook

• Local home prices are declining (-3.0%/yr); year-one equity from $3k of loan paydown is wiped out by about $11k of value loss. Plan a longer hold.
• Nassau County population projected at +7% by 2050 — modest demand growth; plan on rents tracking national, not racing it.

Negotiation context

• It's been on market 36 days — a 3% lower offer ($364k) is reasonable based on typical stale-listing flexibility.
• 3 sale attempts since 8y ago with the ask held roughly flat each time — persistent listings suggest the price (not the market) is what's stuck; bring a comps-based counter.
• Current owner paid $230k; list at $375k implies a 63% gain — meaningful room to come down on a strong offer.

Risks & watch-outs

• Watch-outs: HOA is 28% of rent.
• Climate carrying-cost: major wind risk, 69% 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 $305,214 (18.6% 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. It's been on market 36 days. Have you received any prior offers? Is the seller open to a 19% concession, seller financing, or rate buy-down credit?
3. Built in 1969 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
4. What does the HOA fee cover, when was the last increase, and are there any pending special assessments or reserve-fund shortfalls?
5. 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?
6. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
7. 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?
8. 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?
9. 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.
10. 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.
11. 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.
