What a home in Key Biscayne costs to own

Take the median $1,295,000 listing with 20% down at today’s 7.40% 30-year rate: principal and interest run about $7,173/month. Miami-Dade County’s typical millage of 17.59 puts property tax near $21,904/year after the $50,000 homestead exemption — and that is the reset bill a buyer pays, not the seller’s capped one. Citizens’ average premium in Miami-Dade County is about $1,891/year; newer roofs and inland addresses usually quote below it. All in, plan on roughly $9,156/month plus any HOA or CDD assessment.
