Our bank blanket policy is privately underwritten. A couple of months ago, I did a comparison for a large commercial customer who did not want to renew his flood insurance. If I force-placed it under our private policy, the premium was 4 times
the amount of premium that the customer would pay if he bought an individual policy underwritten by FEMA.
I don't know if everyone has had that experience (if not, I guess we need to get bids on a blanket policy again!) - but that's a substantial difference. Several thousand dollars, in this case.
