What this means for you Summary

Snapshot

  • This is a 3 × 2-bed/1.0-bath units multifamily listed at $675k.

Deal economics

  • At list price, monthly cash flow is $3k ($37k/yr) — positive. Per door: $1k/mo.
  • The deal already cash-flows at list — no discount required.
  • Meets the 1% rule at list price ($9k rent vs $675k).
  • Recommended offer: $655k (3.0% below list) — sets the bar for market timing.
  • Cap rate 11.8% vs local median 2.5% in Hull — 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 67/100 on livability (#168 in MA) — a middle-class / working-renter tenant base. Strengths: employment A+, housing A+, crime A-; Watch: amenities F, commute F, cost of living F.
  • Hull (suburban): math 44% / reading 55% proficiency, ranked #125 of 302 in MA (top 41%) — families likely to look elsewhere, expect single-tenant / working-renter base with shorter leases.
  • Zoned schools: Lillian M Jacobs (math 47% / reading 57%, grade C-, #287 of 938 statewide, top 33%, 362 students, 0% FRL); Memorial Middle (math 32% / reading 47%, grade F, #148 of 305 statewide, top 49%, 172 students, 0% FRL); Hull High (math 74% / reading 74%, grade B+, #60 of 343 statewide, top 19%, 241 students, 0% FRL) — zoned schools average 0% FRL vs 28% district-wide (28 pts lower); this property's tenant base skews higher-income than the district average.
  • Market conditions: 55 active listings in the ZIP; 2 comparable units currently listed for rent nearby; high-income renter base; 1,255 units permitted in Plymouth County in 2024 (411 in 5+ unit buildings).
  • At $9,269/mo this rent would consume 96% of the median local household income ($115k/yr) (locally 281% of renters already pay >50% of income on rent) — very limited rent-growth headroom before tenants either downsize or default.

Forward outlook

  • Local home prices are declining (-3.0%/yr); year-one equity from $5k of loan paydown is wiped out by about $20k of value loss. Plan a longer hold.
  • At projected returns (-3.0% appreciation + 3.0% rent growth), your $189k cash investment doubles in ~7 years — after that, you're playing with house money.

Negotiation context

  • It's been on market 38 days — a 3% lower offer ($655k) is reasonable based on typical stale-listing flexibility.
  • Current owner paid $30k; list at $675k implies a 2150% gain — meaningful room to come down on a strong offer.

Risks & watch-outs

  • Watch-outs: flood insurance adds $56/mo; built in 1920 — expect roof / HVAC / electrical / plumbing capex.
  • Climate carrying-cost: major flood risk; severe wind risk, 80% 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 $654,750 (3.0% below list)

Questions for the listing agent

  1. It's been on market 38 days. Have you received any prior offers? Is the seller open to a 3% concession, seller financing, or rate buy-down credit?
  2. Can we see the unit-by-unit rent roll, current vacancy, and any below-market leases? What's the average tenancy length?
  3. What capital expenditures (roof, boiler, parking lot, exteriors) have been made in the last 5 years, and what's planned in the next 2?
  4. Built in 1920 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
  5. What's the actual annual flood-insurance premium (NFIP or private), and is the property in a SFHA with mandatory coverage?
  6. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
  7. 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?
  8. 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.
  9. 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.
  10. 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.
