If you buy new construction and the home was not substantally complete on 01/2009. you will pay property taxes on unemporved properlty for 2009.
Property taxes will be based on the purchase price you paid. If you paid more than the previous owner, your property taxes should be more that the previous owners taxes.
Once you file homestead your property taxes will be limited to a moderate 3% a year increase
If your home is homesteaded by the previous owner, the homestead will pass to you until you file for your own.
Apparently New Hampshire property taxes are assessed and collected differently than Florida
In Florida property taxes are paid in arrears. The new property tax assessment and Property tax bill for the current year is received in November 2009 Tax is due March 30. 2010. You receive a 4% discount if you pay in November when the bill is received. The discount reduces to 3% paid in Dec, 2% paid in Jan, 1% paid in Feb, 0% if paid in Mar 2010
Congratulations on your decision to move forward and purchase in Florida.
