What this means for you Summary

Snapshot

  • This is a 3-bed/2.0-bath single-family listed at $670k.

Deal economics

  • At list price, monthly cash flow is $-832 ($-10k/yr) — negative.
  • To cash-flow at today's rent, offer at most $523k (21.9% below list).
  • To meet the 1% rule (rent ≥ 1% of price), the offer needs to be $480k (28.4% below list).
  • Recommended offer: $480k (28.4% below list) — sets the bar for 1% rule.
  • Cap rate 5.6% 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: Ps 225 Eileen E Zaglin (The) (math 57% / reading 52%, grade C, #908 of 2,108 statewide, top 46%, 963 students, 84% FRL); Is 98 Bay Academy (math 96% / reading 96%, grade A+, #2 of 729 statewide, top 0%, 1,488 students, 63% 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 (+7.0%/yr); 114 active listings in the ZIP; 5 comparable units currently listed for rent nearby; rentals at typical pace (median 21d on market — plan ~3-4 weeks tenant-placement turnaround); lower-income renter base — watch delinquency; 10,063 units permitted in Kings County in 2024 (9,789 in 5+ unit buildings).
  • At $4,796/mo this rent would consume 132% 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 $38k of equity ($5k loan paydown + $33k appreciation (5.0% 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 ~$61k cash-out refi (75% LTV) — recoverable capital for the next deal without selling this one.

Negotiation context

  • It's been on market 249 days — a 12% lower offer ($590k) is reasonable based on typical stale-listing flexibility.
  • 2 sale attempts 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.

Risks & watch-outs

  • Watch-outs: flood insurance adds $427/mo.
  • Climate carrying-cost: in FEMA flood zone AE (mandatory federal flood insurance); major wind risk, 69% 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 $479,612 (28.4% 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 249 days. Have you received any prior offers? Is the seller open to a 28% concession, seller financing, or rate buy-down credit?
  3. What's the actual annual flood-insurance premium (NFIP or private), and is the property in a SFHA with mandatory coverage?
  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 for-sale + rental construction is in the pipeline within 1–3 miles? Heavy new supply typically softens prices + rents 12–24 months out; constrained supply supports both.

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.
