What this means for you Summary

Snapshot

  • This is a 2 × 4-bed/2.0-bath units multifamily listed at $250k.

Deal economics

  • At list price, monthly cash flow is $754 ($9k/yr) — positive. Per door: $377/mo.
  • The deal already cash-flows at list — no discount required.
  • Meets the 1% rule at list price ($3k rent vs $250k).
  • Recommended offer: $235k (6.0% below list) — sets the bar for market timing.
  • Cap rate 9.9% vs local median 3.9% in Jacksonville — 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 83/100 on livability (#50 in FL, #911 nationally) — a professional / high-income tenant draw. Strengths: amenities A+, commute A+, housing A+.
  • Duval (urban): math 46% / reading 45% proficiency, ranked #48 of 73 in FL (top 66%) — families likely to look elsewhere, expect single-tenant / working-renter base with shorter leases.
  • Market conditions: Rents rising (+1.8%/yr); 399 active listings in the ZIP; 1 comparable units currently listed for rent nearby; lower-income renter base — watch delinquency; 6,503 units permitted in Duval County in 2024 (1,131 in 5+ unit buildings).
  • At $3,098/mo this rent would consume 122% of the median local household income ($31k/yr) (locally 2921% 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 $2k of loan paydown is wiped out by about $8k of value loss. Plan a longer hold.
  • Duval County population projected at +19% by 2050 — long-run rental-demand tailwind backs the buy-and-hold thesis.

Negotiation context

  • It's been on market 87 days — a 6% lower offer ($235k) is reasonable based on typical stale-listing flexibility.
  • 8 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.
  • Current owner paid $135k; list at $250k implies a 85% gain — meaningful room to come down on a strong offer.

Risks & watch-outs

  • Watch-outs: built in 1915 — expect roof / HVAC / electrical / plumbing capex.
  • Climate carrying-cost: severe wind risk, 99% chance of damaging wind over 30y; extreme-heat days projected 7→20/yr by 2055 (HVAC capex compounding) — expect insurance premiums to compound above CPI over the hold.
Recommended offer $235,000 (6.0% below list)

Questions for the listing agent

  1. It's been on market 87 days. Have you received any prior offers? Is the seller open to a 6% 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 1915 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
  5. Why hasn't it sold? Are there any deal-killer items the seller is aware of (foundation, flood, title, zoning, code violations)?
  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.
