What this means for you Summary

Snapshot

  • This is a 2-bed/1.0-bath condo listed at $525k.

Deal economics

  • At list price, monthly cash flow is $819 ($10k/yr) — positive.
  • The deal already cash-flows at list — no discount required.
  • Meets the 1% rule at list price ($6k rent vs $525k).
  • Cap rate 8.2% vs local median 2.6% in New York — 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 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 (+8.7%/yr); 127 active listings in the ZIP; 12 comparable units currently listed for rent nearby; rentals leasing fast (median 7d on market — plan ~1-2 weeks tenant-placement turnaround); high-income renter base; 10,063 units permitted in Kings County in 2024 (9,789 in 5+ unit buildings).
  • At $6,294/mo this rent would consume 61% of the median local household income ($123k/yr) (locally 2717% of renters already pay >50% of income on rent) — very limited rent-growth headroom before tenants either downsize or default.

Forward outlook

  • In year one you build about $25k of equity ($4k loan paydown + $22k appreciation (4.1% local appreciation)).
  • Kings County population projected at +13% by 2050 — modest demand growth; plan on rents tracking national, not racing it.
  • At projected returns (4.1% appreciation + 8.0% rent growth), your $147k cash investment doubles in ~4 years — after that, you're playing with house money.
  • By year 2, paydown + projected appreciation supports a ~$41k cash-out refi (75% LTV) — recoverable capital for the next deal without selling this one.

Negotiation context

  • Only 14 days on market — expect competitive offers; lowballing is unlikely to land.

Risks & watch-outs

  • Watch-outs: built in 1910 — expect roof / HVAC / electrical / plumbing capex.
  • Climate carrying-cost: major wind risk, 27% chance of damaging wind over 30y; extreme-heat days projected 7→13/yr by 2055 (HVAC capex compounding) — expect insurance premiums to compound above CPI over the hold.
Recommended offer $525,000

Questions for the listing agent

  1. Built in 1910 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
  2. What does the HOA fee cover, when was the last increase, and are there any pending special assessments or reserve-fund shortfalls?
  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. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
  5. 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?
  6. 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?
  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 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.
