An estimate, not a loan offer. The rate and insurance are assumptions to edit with your own quotes; Florida insurance varies widely by age, construction and distance to the coast. Flood insurance and PMI are not included.
Estimate: the price times the Miami-Dade County average total millage (18.49 mills, Florida Department of Revenue, 2025 average total millage by county), less the homestead exemptions. The actual bill depends on the city, the assessed value and special assessments. Save Our Homes then caps annual assessment increases at 3% or inflation, whichever is lower.
Inside the 1% annual chance floodplain. Lenders require flood insurance on a financed home; ask for the elevation certificate.
