What this means for you Summary

Snapshot

  • This is a 1-bed/2.0-bath condo listed at $345k. Condition is rated good.

Deal economics

  • At list price, monthly cash flow is $-347 ($-4k/yr) — negative.
  • The deal already cash-flows at list — no discount required.
  • Meets the 1% rule at list price ($4k rent vs $345k).
  • Cap rate 6.6% vs local median 1.5% in Miami Beach — 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 80/100 on livability (#108 in FL, #1,672 nationally) — a professional / high-income tenant draw. Strengths: crime A+, commute A+, health & safety A+; Watch: housing C-, amenities D-, 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 rising (+3.5%/yr); 670 active listings in the ZIP; 3 comparable units currently listed for rent nearby; rentals at typical pace (median 20d on market — plan ~3-4 weeks tenant-placement turnaround); solid renter incomes; 10,051 units permitted in Miami-Dade County in 2024 (7,758 in 5+ unit buildings).
  • This rent runs 42% of the median local income ($107k/yr) — at the standard rent-burdened threshold; future hikes will face affordability resistance.

Forward outlook

  • In year one you build about $6k of equity ($2k loan paydown + $3k appreciation (1.0% local appreciation)).
  • Miami-Dade County population projected at +28% by 2050 — long-run rental-demand tailwind backs the buy-and-hold thesis.
  • By year 6, paydown + projected appreciation supports a ~$33k cash-out refi (75% LTV) — recoverable capital for the next deal without selling this one.

Negotiation context

  • Only 1 days on market — expect competitive offers; lowballing is unlikely to land.

Risks & watch-outs

  • Watch-outs: flood insurance adds $427/mo.
  • Climate carrying-cost: in FEMA flood zone AE (mandatory federal flood insurance); 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 $345,000

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. Built in 1970 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
  3. What's the actual annual flood-insurance premium (NFIP or private), and is the property in a SFHA with mandatory coverage?
  4. What does the HOA fee cover, when was the last increase, and are there any pending special assessments or reserve-fund shortfalls?
  5. Any open or pending special assessments — roof, HVAC, plumbing, elevator, façade? What's the per-unit balance and payoff schedule, and is the seller paying it off at close or rolling it to the buyer?
  6. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
  7. Schools are A-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.
