What this means for you Summary

Snapshot

  • This is a 2 × 3-bed/1.5-bath units multifamily listed at $649k.

Deal economics

  • At list price, monthly cash flow is $3k ($39k/yr) — positive. Per door: $2k/mo.
  • The deal already cash-flows at list — no discount required.
  • Meets the 1% rule at list price ($10k rent vs $649k).
  • Recommended offer: $591k (9.0% below list) — sets the bar for market timing.
  • Cap rate 13.1% 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.
  • Market conditions: Rents rising fast (+7.0%/yr); 114 active listings in the ZIP; 1 comparable units currently listed for rent nearby; lower-income renter base — watch delinquency; 10,063 units permitted in Kings County in 2024 (9,789 in 5+ unit buildings).
  • At $9,852/mo this rent would consume 271% of the median local household income ($44k/yr) (locally 4426% 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 $37k of equity ($4k loan paydown + $32k appreciation (5.0% local appreciation)).
  • Kings County population projected at +13% by 2050 — modest demand growth; plan on rents tracking national, not racing it.
  • At projected returns (5.0% appreciation + 7.0% rent growth), your $182k cash investment doubles in ~3 years — after that, you're playing with house money.
  • By year 2, paydown + projected appreciation supports a ~$59k cash-out refi (75% LTV) — recoverable capital for the next deal without selling this one.

Negotiation context

  • It's been on market 114 days — a 9% lower offer ($591k) is reasonable based on typical stale-listing flexibility.
  • 3 sale attempts since 2y ago; this cycle's ask has dropped $50k (7%) from the opening price — seller is motivated, your offer sets the floor, not the list.
  • Current owner paid $146k; list at $649k implies a 345% gain — meaningful room to come down on a strong offer.

Risks & watch-outs

  • Watch-outs: flood insurance adds $427/mo; built in 1940 — expect roof / HVAC / electrical / plumbing capex.
  • Climate carrying-cost: in FEMA flood zone AE (mandatory federal flood insurance); major wind risk, 72% 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 $590,590 (9.0% below list)

Questions for the listing agent

  1. It's been on market 114 days. Have you received any prior offers? Is the seller open to a 9% concession, seller financing, or rate buy-down credit?
  2. Can we see the unit-by-unit rent roll, current vacancy, and any below-market leases? What's the average tenancy length?
  3. What capital expenditures (roof, boiler, parking lot, exteriors) have been made in the last 5 years, and what's planned in the next 2?
  4. Built in 1940 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
  5. What's the actual annual flood-insurance premium (NFIP or private), and is the property in a SFHA with mandatory coverage?
  6. Why hasn't it sold? Are there any deal-killer items the seller is aware of (foundation, flood, title, zoning, code violations)?
  7. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
  8. 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?
  9. 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?
  10. 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.
  11. 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.
  12. 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.
