What this means for you Summary

Snapshot

  • This is a 2 × 3-bed/1.0-bath units multifamily listed at $775k. Condition is rated fair.

Deal economics

  • At list price, monthly cash flow is $-128 ($-2k/yr) — negative. Per door: $-64/mo.
  • To cash-flow at today's rent, offer at most $757k (2.4% below list).
  • To meet the 1% rule (rent ≥ 1% of price), the offer needs to be $662k (14.6% below list).
  • Recommended offer: $662k (14.6% below list) — sets the bar for 1% rule.

Location & tenants

  • Location reads 80/100 on livability (#72 in NJ, #1,762 nationally) — a professional / high-income tenant draw. Strengths: crime A+, commute A+, employment A+; Watch: amenities D-, cost of living F.
  • Ridgefield Park School District (suburban): math 18% / reading 39% proficiency, ranked #348 of 472 in NJ (top 74%) — low school quality limits family demand, transient renter base, plan for 1-2y turnover.
  • Market conditions: 1 active listings in the ZIP; 3,488 units permitted in Bergen County in 2024 (1,610 in 5+ unit buildings).

Forward outlook

  • In year one you build about $29k of equity ($5k loan paydown + $23k appreciation (3.0% local appreciation)).
  • Bergen County population projected at +20% by 2050 — long-run rental-demand tailwind backs the buy-and-hold thesis.
  • By year 2, paydown + projected appreciation supports a ~$47k cash-out refi (75% LTV) — recoverable capital for the next deal without selling this one.

Negotiation context

  • It's been on market 40 days — a 3% lower offer ($752k) is reasonable based on typical stale-listing flexibility.

Risks & watch-outs

  • Watch-outs: built in 1906 — 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.
Recommended offer $661,800 (14.6% 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 40 days. Have you received any prior offers? Is the seller open to a 15% concession, seller financing, or rate buy-down credit?
  3. Can we see the unit-by-unit rent roll, current vacancy, and any below-market leases? What's the average tenancy length?
  4. What capital expenditures (roof, boiler, parking lot, exteriors) have been made in the last 5 years, and what's planned in the next 2?
  5. Have any recent inspections been done? Can we get a copy of the seller's disclosures and any deferred-maintenance estimates?
  6. Built in 1906 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
  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. 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.
  10. 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.
  11. 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.
