Flood Insurance rates increased

[Paresh Patel]

We purchased a two flat (converted from single family home) a year ago. Paid for flood insurance when we closed on the deal. Now we get a letter from FEMA stating our flood insurance premium is more than doubled. Reason, they show as excessive risk. Last claim was from a prior owner in the year 2013. Any remedy to rectify and find out what will be a good way find out what will be true rate. Thank you,in advance for your help and suggestions.
