Know Before You Own
Home cost calculator

What will it really cost each month?

The loan payment is only part of it. Add Florida property tax, insurance, flood insurance, lot rent and park fees to see the whole monthly number, for a regular house or a manufactured home.

What are you buying?

We’ll find the county’s tax rate and FEMA’s flood zone for you. Nothing is saved.

Example number. Florida quotes vary a lot, so get a real one.

Look up the address above to see the flood zone.

Fire, trash or special assessments on the tax bill.

Estimated monthly cost

An estimate for planning, not a loan offer or financial advice. Property tax uses the county’s 2025 average rate from the Florida Department of Revenue and assumes the home is assessed at its price; your bill depends on the exact city and taxing districts.

Before you trust the monthly number

  • Insurance can change everything. In Florida, homeowners and flood insurance can cost as much as the loan payment. Get quotes before you make an offer. Our checklist’s flood section covers what to ask.
  • Lot rent goes up. On a leased lot, ask how much rent has risen in recent years and what the lease allows. See leased lot questions.
  • Taxes can rise after you buy. A sale usually resets the home’s assessed value to its market value, so the seller’s tax bill may be lower than yours will be.
  • Chattel loans cost more. Manufactured homes on leased land are usually financed as personal property, with higher rates and shorter terms than a mortgage. Compare at least two lenders.
