Even if we had the rate book in front of us your question could not be answered.
A 1963, $350,000 rancher will have flood insurance premiums 5x the amount of the 1.5 million dollar home next door if within the CCL. This will also apply to any home in the FEMA designated flood zone. As John disclosed, the elevation certificate is essential if in a flood zone.
You do not state if the subject home IS in a flood zone. If not, the premium could be as low at $600 annually.
As others have stated, those home in a flood zone are going to prove problematic.
In Sept of 2013 a home previously had a flood insurance premium of $2,400 annually. The new premium for the buyer was quoted to be $46,000! That resulted in NO SALE!
What will prove accurate for you will be type and age of contruction, location and insurance carrier. Time to place a call to your home insurance company.
Don't think for a minute the situation described is a Florida problem.
Best of success,
