What this means for you Summary
Snapshot
- This is a 2-bed/1.0-bath condo listed at $599k.
Deal economics
- At list price, monthly cash flow is $-877 ($-11k/yr) — negative.
- To cash-flow at today's rent, offer at most $472k (21.2% below list).
- To meet the 1% rule (rent ≥ 1% of price), the offer needs to be $421k (29.6% below list).
- Recommended offer: $421k (29.6% below list) — sets the bar for 1% rule.
- Cap rate 4.7% 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 (+6.0%/yr); 74 active listings in the ZIP; 10 comparable units currently listed for rent nearby; rentals at typical pace (median 27d on market — plan ~3-4 weeks tenant-placement turnaround); 10,063 units permitted in Kings County in 2024 (9,789 in 5+ unit buildings).
- At $4,214/mo this rent would consume 78% of the median local household income ($65k/yr) (locally 6603% 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 $64k of equity ($4k loan paydown + $60k 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 ~$103k cash-out refi (75% LTV) — recoverable capital for the next deal without selling this one.
Negotiation context
- It's been on market 67 days — a 6% lower offer ($563k) 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 $66/mo; built in 1926 — expect roof / HVAC / electrical / plumbing capex.
- Climate carrying-cost: severe flood risk; major wind risk, 62% 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.
Questions for the listing agent
- 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?
- It's been on market 67 days. Have you received any prior offers? Is the seller open to a 30% concession, seller financing, or rate buy-down credit?
- Built in 1926 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
- What's the actual annual flood-insurance premium (NFIP or private), and is the property in a SFHA with mandatory coverage?
- 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?
- Why hasn't it sold? Are there any deal-killer items the seller is aware of (foundation, flood, title, zoning, code violations)?
- Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
- 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?
- 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?
- 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?
- 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.
- 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.
- 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.
