Thank you David, for your reply.
After putting up this thread, I was sent a copy of the flood map by the loan officer. The rather long and skinny property backs up to a water course. Roughly half the property is in a flood zone but the office and a storage building, situated street side, are not in any flood zone. Only some of the M/H rental sites in the back portion of the property are within the flood zone. No housing is included as collateral on this proposed loan.
One begins to feel a bit like Chicken Little worrying about the sky falling, wondering if some overlooked change in flood regulations requires the lender to compel the borrower to carry flood insurance that protects his mobile home tenants.
I wasn't having any luck yesterday, doing searches online for guidance. The actual regs with their supporting guidance didn't offer clarity for my pea-brain. A couple searches came back here to BOL but even those references were a bit oblique.
