What are the property taxes and any homestead implications?

Miami-Dade County real-estate taxes are administered by the Miami-Dade Property Appraiser (current assessment + tax-bill data at https://www.miamidade.gov/pa/property_search.asp). A new buyer's tax bill resets based on the sale price and the buyer's own exemption status; the first full tax bill after purchase is often meaningfully higher than the seller's prior bill. Florida's Homestead Exemption reduces the taxable value for a primary residence — eligibility requirements and filing windows are published at https://www.miamidade.gov/pa/exemptions_homestead.asp. The statewide Florida Department of Revenue property-tax reference is at https://floridarevenue.com/property/.

Is it in a flood zone, and what does that mean for insurance?

Authoritative flood-zone designation for any U.S. address is published by FEMA on the National Flood Hazard Layer at https://msc.fema.gov/portal/home. Coastal South Florida includes properties in multiple flood-risk zones (AE, V, VE, X). Lenders typically require flood insurance in high-risk zones. The FEMA Risk Rating 2.0 methodology (premiums based on elevation, construction type, claims history, distance to water) is documented at https://www.fema.gov/flood-insurance/risk-rating. Florida-specific flood-insurance program data is at https://floridarevenue.com/.
