What a home in Key Colony costs to own

Take the median $1,100,000 listing with 20% down at today’s 6.95% 30-year rate: principal and interest run about $5,825/month. Monroe County’s typical millage of 8.82 puts property tax near $9,257/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 Monroe County is about $4,380/year; newer roofs and inland addresses usually quote below it. All in, plan on roughly $6,962/month plus any HOA or CDD assessment.
