What this means for you Summary

Snapshot

  • This is a 2 × 3-bed/1.0-bath units multifamily listed at $880k.

Deal economics

  • At list price, monthly cash flow is $1k ($17k/yr) — positive. Per door: $728/mo.
  • The deal already cash-flows at list — no discount required.
  • Meets the 1% rule at list price ($9k rent vs $880k).
  • Recommended offer: $774k (12.0% below list) — sets the bar for market timing.

Location & tenants

  • Location reads 77/100 on livability (#208 in FL, #3,222 nationally) — a middle-class / working-renter tenant base. Strengths: crime A+, employment A+, health & safety A+; Watch: amenities F, cost of living F.
  • Miami-Dade (suburban): math 45% / reading 54% proficiency, ranked #40 of 73 in FL (top 55%) — families likely to look elsewhere, expect single-tenant / working-renter base with shorter leases; 64% free/reduced lunch — lower-income household profile, screen leases tightly.
  • Market conditions: Rents soft (-0.7%/yr); 338 active listings in the ZIP; 1 comparable units currently listed for rent nearby; 10,051 units permitted in Miami-Dade County in 2024 (7,758 in 5+ unit buildings).
  • At $9,427/mo this rent would consume 194% of the median local household income ($58k/yr) (locally 3226% 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 $6k of loan paydown is wiped out by about $26k of value loss. Plan a longer hold.
  • Miami-Dade County population projected at +28% by 2050 — long-run rental-demand tailwind backs the buy-and-hold thesis.

Negotiation context

  • It's been on market 142 days — a 12% lower offer ($774k) is reasonable based on typical stale-listing flexibility.
  • 9 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 $740k; 19% above their basis — modest negotiation headroom, anchor on the comps not their cost.

Risks & watch-outs

  • Climate carrying-cost: severe wind risk, 99% chance of damaging wind over 30y; extreme-heat days projected 7→28/yr by 2055 (HVAC capex compounding) — expect insurance premiums to compound above CPI over the hold.
Recommended offer $774,400 (12.0% below list)

Questions for the listing agent

  1. It's been on market 142 days. Have you received any prior offers? Is the seller open to a 12% 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 1960 — 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.
