All of these homes predate Florida's 2002 statewide building code. So roof age, window protection and the wind mitigation report matter a great deal for insurance.

In addition, most Florida insurers ask for a four-point inspection on homes 30 years or older. It covers the roof, electrical, plumbing and HVAC. Updated systems usually make coverage easier to place.

Here is what the median San Castle price means in Florida closing terms. At $499,000, a 20% down payment comes to about $100,000, leaving a loan near $399,000.

Florida then taxes that loan twice. First, documentary stamp tax on the note runs 35 cents per $100, or about $1,397. Next, the intangible tax of 0.2% adds about $798. Buyers normally pay both at closing.

On the seller side, Florida deed stamps cost 70 cents per $100 of price. At the San Castle median, that is about $3,493.

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.
