What a home in Key Biscayne costs to own
Take the median $1,527,500 listing with 20% down at today’s 6.71% 30-year rate: principal and interest run about $7,893/month. Miami-Dade County’s typical millage of 17.59 puts property tax near $25,994/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 $10,217/month plus any HOA or CDD assessment.
