What this means for you Summary
Snapshot
- This is a 2 × 2-bed/1.0-bath units multifamily listed at $525k.
Deal economics
- At list price, monthly cash flow is $2k ($19k/yr) — positive. Per door: $791/mo.
- The deal already cash-flows at list — no discount required.
- Meets the 1% rule at list price ($6k rent vs $525k).
- Recommended offer: $462k (12.0% below list) — sets the bar for market timing.
- Cap rate 9.9% 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: 78 active listings in the ZIP; lower-income renter base — watch delinquency; 6,929 units permitted in Bronx County in 2024 (6,829 in 5+ unit buildings).
- At $6,118/mo this rent would consume 202% of the median local household income ($36k/yr) (locally 7852% 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 $43k of equity ($4k loan paydown + $39k appreciation (7.5% local appreciation)).
- Bronx County population projected at +21% by 2050 — long-run rental-demand tailwind backs the buy-and-hold thesis.
- At projected returns (7.5% appreciation + 3.0% rent growth), your $147k cash investment doubles in ~3 years — after that, you're playing with house money.
- By year 2, paydown + projected appreciation supports a ~$68k cash-out refi (75% LTV) — recoverable capital for the next deal without selling this one.
Negotiation context
- It's been on market 330 days — a 12% lower offer ($462k) is reasonable based on typical stale-listing flexibility.
- 4 sale attempts since 18y ago; this cycle's ask has dropped $125k (19%) from the opening price — seller is motivated, your offer sets the floor, not the list.
- Current owner paid $11k; list at $525k implies a 4672% gain — meaningful room to come down on a strong offer.
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→15/yr by 2055 (HVAC capex compounding) — expect insurance premiums to compound above CPI over the hold.
Questions for the listing agent
- It's been on market 330 days. Have you received any prior offers? Is the seller open to a 12% concession, seller financing, or rate buy-down credit?
- Can we see the unit-by-unit rent roll, current vacancy, and any below-market leases? What's the average tenancy length?
- What capital expenditures (roof, boiler, parking lot, exteriors) have been made in the last 5 years, and what's planned in the next 2?
- Built in 1910 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
- 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?
- 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.
