What a home in Geiger Key costs to own
Take the median $724,000 listing with 20% down at today’s 7.24% 30-year rate: principal and interest run about $3,947/month. Monroe County’s typical millage of 8.82 puts property tax near $5,942/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 $4,807/month plus any HOA or CDD assessment.
