What this means for you Summary

Snapshot

• This is a 1-bed/1.0-bath condo listed at $701k.

Deal economics

• At list price, monthly cash flow is $-2k ($-22k/yr) — negative.
• To cash-flow at today's rent, offer at most $441k (37.0% below list).
• To meet the 1% rule (rent ≥ 1% of price), the offer needs to be $386k (44.9% below list).
• Recommended offer: $386k (44.9% below list) — sets the bar for 1% rule.
• Cap rate 3.2% vs local median 2.6% in New York — meaningfully above typical; check what's discounted (condition, days-on-market, listing class) to confirm the premium yield is real.

Location & tenants

• Location reads 75/100 on livability (#268 in NY, #4,188 nationally) — a middle-class / working-renter tenant base. Strengths: amenities A+, commute A+, health & safety A; Watch: crime F, cost of living F.
• Market conditions: Rents rising fast (+5.7%/yr); 248 active listings in the ZIP; 2 comparable units currently listed for rent nearby; high-income renter base; 10,063 units permitted in Kings County in 2024 (9,789 in 5+ unit buildings).

Forward outlook

• In year one you build about $75k of equity ($5k loan paydown + $70k appreciation (10.0% local appreciation)).
• Kings County population projected at +13% by 2050 — modest demand growth; plan on rents tracking national, not racing it.
• By year 2, paydown + projected appreciation supports a ~$120k cash-out refi (75% LTV) — recoverable capital for the next deal without selling this one.

Negotiation context

• It's been on market 342 days — a 12% lower offer ($617k) is reasonable based on typical stale-listing flexibility.

Risks & watch-outs

• Climate carrying-cost: major wind risk, 61% chance of damaging wind over 30y; extreme-heat days projected 7→15/yr by 2055 (HVAC capex compounding) — expect insurance premiums to compound above CPI over the hold.

Recommended offer $386,102 (44.9% 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 342 days. Have you received any prior offers? Is the seller open to a 45% concession, seller financing, or rate buy-down credit?
3. 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?
4. Why hasn't it sold? Are there any deal-killer items the seller is aware of (foundation, flood, title, zoning, code violations)?
5. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
6. 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?
7. Crime grade is F 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?
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.
