Here is what the median Center Island price means in Florida closing terms. At $1.93M, a 20% down payment comes to about $385,000, leaving a loan near $1.54M.

Florida then taxes that loan twice. First, documentary stamp tax on the note runs 35 cents per $100, or about $5,390. Next, the intangible tax of 0.2% adds about $3,080. Buyers normally pay both at closing.

On the seller side, Florida deed stamps cost 70 cents per $100 of price. At the Center Island median, that is about $13,475.

Finally, owner-occupants should file for the Florida homestead exemption by March 1. It removes up to $50,000 of assessed value. After that, Save Our Homes caps yearly assessment increases at 3% or inflation, whichever is lower. To see what these numbers mean for your budget, get pre-approved before you tour.
