What this means for you Summary

Snapshot

  • This is a 1×1bd/1.0ba + 2×2bd/1.0ba units multifamily listed at $200k.

Deal economics

  • At list price, monthly cash flow is $1k ($18k/yr) — positive. Per door: $498/mo.
  • The deal already cash-flows at list — no discount required.
  • Meets the 1% rule at list price ($4k rent vs $200k).
  • Recommended offer: $197k (1.5% below list) — sets the bar for market timing.
  • Cap rate 15.3% vs local median 7.7% in Niagara Falls — 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 60/100 on livability (#956 in NY) — a middle-class / working-renter tenant base. Strengths: cost of living A+, housing A+; Watch: schools F, crime F, amenities F.
  • Niagara Falls City School District (urban): math 26% / reading 34% proficiency, ranked #578 of 590 in NY (top 98%) — families likely to look elsewhere, expect single-tenant / working-renter base with shorter leases; 66% free/reduced lunch — lower-income household profile, screen leases tightly.
  • Market conditions: Rents rising fast (+8.8%/yr); 164 active listings in the ZIP; lower-income renter base — watch delinquency; 167 units permitted in Niagara County in 2024 (0 in 5+ unit buildings).
  • At $3,506/mo this rent would consume 122% of the median local household income ($35k/yr) (locally 954% 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 $21k of equity ($1k loan paydown + $20k appreciation (10.0% local appreciation)).
  • Niagara County population projected at -19% by 2050 — secular population decline; favor cash flow + early exit over multi-decade hold.
  • At projected returns (10.0% appreciation + 8.0% rent growth), your $56k cash investment doubles in ~2 years — after that, you're playing with house money.
  • By year 2, paydown + projected appreciation supports a ~$34k cash-out refi (75% LTV) — recoverable capital for the next deal without selling this one.

Negotiation context

  • It's been on market 20 days — a 2% lower offer ($197k) is reasonable based on typical stale-listing flexibility.
  • 4 sale attempts since 10y 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.
  • Current owner paid $31k; list at $200k implies a 545% gain — meaningful room to come down on a strong offer.

Risks & watch-outs

  • Watch-outs: built in 1920 — expect roof / HVAC / electrical / plumbing capex.
Recommended offer $196,901 (1.5% below list)

Questions for the listing agent

  1. Can we see the unit-by-unit rent roll, current vacancy, and any below-market leases? What's the average tenancy length?
  2. What capital expenditures (roof, boiler, parking lot, exteriors) have been made in the last 5 years, and what's planned in the next 2?
  3. Built in 1920 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
  4. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
  5. Schools are F-rated, which usually means shorter tenancies and higher turnover. Who's the typical renter profile here, and what's been the actual vacancy rate?
  6. 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?
  7. 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.
  8. 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.
  9. 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.
