What this means for you Summary

Snapshot

  • This is a 2 × 3-bed/1.0-bath units multifamily listed at $129k.

Deal economics

  • At list price, monthly cash flow is $1k ($18k/yr) — positive. Per door: $734/mo.
  • The deal already cash-flows at list — no discount required.
  • Meets the 1% rule at list price ($3k rent vs $129k).
  • Cap rate 19.9% vs local median 6.3% in Amsterdam — 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 (#247 in NY, #3,884 nationally) — a middle-class / working-renter tenant base. Strengths: cost of living A+, housing A+, health & safety A+; Watch: crime F, employment F.
  • Amsterdam City School District (town): math 35% / reading 41% proficiency, ranked #546 of 590 in NY (top 92%) — families likely to look elsewhere, expect single-tenant / working-renter base with shorter leases.
  • Zoned schools: Amsterdam High School (math 75% / reading 82%, grade A-, #563 of 1,100 statewide, top 52%, 1,179 students, 68% FRL) — zoned schools average 68% FRL vs 40% district-wide (28 pts higher); higher-poverty schools than district average — tighter screening recommended.
  • Zoned-school proficiency averages 78% at this address vs 38% district-wide (+40 pts) — the actual schools serving this property are materially stronger than the Amsterdam City School District average implies; a family-tenant draw the district grade alone would hide.
  • Market conditions: 164 active listings in the ZIP; 210 units permitted in Montgomery County in 2024 (168 in 5+ unit buildings).

Forward outlook

  • In year one you build about $14k of equity ($892 loan paydown + $13k appreciation (10.0% local appreciation)).
  • Montgomery County population projected at -11% by 2050 — secular population decline; favor cash flow + early exit over multi-decade hold.
  • At projected returns (10.0% appreciation + 3.0% rent growth), your $36k cash investment doubles in ~2 years — after that, you're playing with house money.
  • By year 3, paydown + projected appreciation supports a ~$35k cash-out refi (75% LTV) — recoverable capital for the next deal without selling this one.

Negotiation context

  • Only 4 days on market — expect competitive offers; lowballing is unlikely to land.

Risks & watch-outs

  • Watch-outs: built in 1910 — expect roof / HVAC / electrical / plumbing capex.
Recommended offer $129,000

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 1910 — 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 D-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.
