Miami offers no state income tax, strong international demand, and a lifestyle that draws buyers from across the US and world. But Florida's insurance crisis has added thousands of dollars per year to true ownership costs that most calculators don't account for.
Pre-filled with Miami median values. Important: update the annual home insurance to ~$10,000/year in the detailed settings — the $1,800 national default significantly understates real Miami insurance costs and will make your result inaccurate.

Miami's appeal is real: no state income tax, Florida's homestead exemption, warm weather, beaches, and international cultural mix create persistent demand from New Yorkers, Californians, and Latin American buyers. The city's transformation into a genuine financial and tech hub has further sustained prices.
The critical complication in 2026: Florida's homeowner insurance market has experienced a genuine crisis. Many large insurers have left the state entirely. Annual premiums on a $620,000 Miami home now commonly run $8,000–15,000/year — 4–8x the national average. This single factor must be included in any honest rent vs buy comparison.
Critical: our calculator defaults to $1,800/year home insurance — the national average. For Miami, update this to $8,000–12,000/year in the detailed settings. This single change can shift your break-even point by 2–3 years and is the most important Miami-specific adjustment to make.
| Cost | National average | Miami estimate | Extra monthly cost |
|---|---|---|---|
| Homeowner insurance | $1,800/yr ($150/mo) | $10,000/yr ($833/mo) | +$683/mo |
| Flood insurance (if required) | $0 | $700–2,000/yr | +$58–167/mo |
Florida has no state income tax, saving high earners $5,000–20,000+/year compared to California or New York. The homestead exemption reduces assessed value by $50,000 for primary residences, saving approximately $430/year in property taxes. For high-income transplants from tax-heavy states, these savings can justify higher housing costs.
Miami has one of the largest condo markets in the US. Florida's post-Surfside legislation (2021 collapse) now requires older condos to complete structural inspections and fund proper reserves — driving HOA fees sharply higher in many buildings, with some having doubled or tripled. Always obtain the full HOA financials, reserve fund status, and any pending special assessments before buying any Miami condo.
Miami is one of the most flood-vulnerable major cities in the US. Some neighborhoods already experience "sunny day flooding" during high tides. For buyers with 30-year mortgage horizons, understanding specific property elevation and flood history is important due diligence beyond just the purchase price. Check FEMA flood maps for any specific address before making an offer.
