Florida cost of ownership
Estimated property tax
$60,256/yr

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.

The full yearly cost of owning this home: property tax levy by levy from the published millage of the parcel’s taxing district (a mailing city is not always inside its city limits), the Save Our Homes cap, HOA and the insurance quotes to get.
