How does Florida property tax affect conventional underwriting?
Materially. Florida county millage rates and assessment basis determine the buyer's monthly tax escrow, which counts in the housing payment for DTI. A property's tax can reset on transfer (Save Our Homes doesn't transfer to new owners), so the buyer's projected tax is often higher than the seller's current tax.
What this actually means.
Florida property tax math: assessed value × millage rate (varies by county and special districts) = annual tax. On purchase, the assessed value typically resets to market value. Save Our Homes (the 3% assessment cap on homestead) applies to the new owner's homestead only after they file — not from the prior owner. Lenders project the tax escrow based on the new assessed value, which can spike DTI compared to early estimates. Always run real numbers. This is general information, not tax advice.
Where this can move.
Florida insurance premiums, property tax millage and Save Our Homes rules, county property-appraiser practice, HOA dues, CDD fees, and condo law can change the answer.
