Purchase in a Flood Zone

[Ben Matityahu]

What are the thing to be aware of when buying a Multifamily property in a Fema flood zone as far as insurance is concerned? 

1. is it very costly ? what are the potential costs ? 

2. can a new purchaser denied from purchasing new policy ?

3. does it matter how many units does the property contain (multifamily or single family ) and are they treated the same ?  

any information would be very appreciated as I live in florida and flood zones are a consideration in any 

Regards,
