What a home in Marathon costs to own

Take the median $1,249,000 listing with 20% down at today’s 6.71% 30-year rate: principal and interest run about $6,454/month. Monroe County’s typical millage of 8.82 puts property tax near $10,570/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 $7,700/month plus any HOA or CDD assessment.
