What this means for you Summary

Snapshot

  • This is a 1-bed/1.0-bath condo listed at $215k.

Deal economics

  • At list price, monthly cash flow is $-147 ($-2k/yr) — negative.
  • The deal already cash-flows at list — no discount required.
  • Meets the 1% rule at list price ($2k rent vs $215k).
  • Recommended offer: $189k (12.0% below list) — sets the bar for market timing.
  • Cap rate 5.5% 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 (+11.6%/yr); 345 active listings in the ZIP; 1 comparable units currently listed for rent nearby; 6,929 units permitted in Bronx County in 2024 (6,829 in 5+ unit buildings).
  • This rent runs 39% of the median local income ($75k/yr) — at the standard rent-burdened threshold; future hikes will face affordability resistance.

Forward outlook

  • Local home prices are declining (-3.0%/yr); year-one equity from $1k of loan paydown is wiped out by about $6k of value loss. Plan a longer hold.
  • Bronx County population projected at +21% by 2050 — long-run rental-demand tailwind backs the buy-and-hold thesis.

Negotiation context

  • It's been on market 127 days — a 12% lower offer ($189k) is reasonable based on typical stale-listing flexibility.
  • 9 sale attempts since 20y ago 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: HOA is 25% of rent; built in 1953 — expect roof / HVAC / electrical / plumbing capex.
  • Climate carrying-cost: major flood risk; major wind risk, 27% chance of damaging wind over 30y; extreme-heat days projected 7→14/yr by 2055 (HVAC capex compounding) — expect insurance premiums to compound above CPI over the hold.
Recommended offer $189,200 (12.0% 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 127 days. Have you received any prior offers? Is the seller open to a 12% concession, seller financing, or rate buy-down credit?
  3. Built in 1953 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
  4. What does the HOA fee cover, when was the last increase, and are there any pending special assessments or reserve-fund shortfalls?
  5. 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?
  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. 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?
  11. 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.
  12. 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.
  13. 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.
