What this means for you Summary

Snapshot

  • This is a 2-bed/1.0-bath condo listed at $800k.

Deal economics

  • At list price, monthly cash flow is $-816 ($-10k/yr) — negative.
  • To cash-flow at today's rent, offer at most $682k (14.8% below list).
  • To meet the 1% rule (rent ≥ 1% of price), the offer needs to be $597k (25.4% below list).
  • Recommended offer: $597k (25.4% below list) — sets the bar for 1% rule.
  • Cap rate 5.1% 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.
  • Zoned schools: Elm Tree Elementary School (math 27% / reading 52%, grade F, #1,444 of 2,108 statewide, top 71%, 806 students, 94% FRL); Jhs 383 Philippa Schuyler (math 32% / reading 67%, grade C, #280 of 729 statewide, top 40%, 822 students, 85% FRL); Midwood High School (math 94% / reading 96%, grade A+, #83 of 1,100 statewide, top 8%, 4,062 students, 73% FRL).
  • Market conditions: Rents rising fast (+4.4%/yr); 146 active listings in the ZIP; 15 comparable units currently listed for rent nearby; rentals leasing fast (median 5d 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 $5,965/mo this rent would consume 53% of the median local household income ($135k/yr) (locally 3722% 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 $50k of equity ($6k loan paydown + $44k appreciation (5.5% 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 ~$80k cash-out refi (75% LTV) — recoverable capital for the next deal without selling this one.

Negotiation context

  • It's been on market 59 days — a 3% lower offer ($776k) is reasonable based on typical stale-listing flexibility.

Risks & watch-outs

  • Climate carrying-cost: major wind risk, 27% 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 $596,501 (25.4% 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. It's been on market 59 days. Have you received any prior offers? Is the seller open to a 25% 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. 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. 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?
  8. 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.
  9. 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.
  10. 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.
