I'm hearing a lot of people say shop for private insurance, I need to try this, but I do know that in my nieghborhood, is in a 100 year flood zone (6 inches of flood, every 100 years). when the hosues were put in, they were required to have a flood cert done, which we did. We did an inexpensive build (used manufactured homes) and built them to standards that the city said. foundations bring the houses above the flood line by a brick or two. Neighbors had a federally backed loan, and were required to have an engineered hills built. I'm sure it was spendy, but they told me at the time, that it meant they didn't have to pay for flood insurance. Then they lost the houses in forclosure/sales, etc, and new people bought them. THESE people are being required by lenders to pay for flood insurance! I am pretty sure that if they had the flood cert done ($225) or looked up the original (its only been 12 years) that they wouldn't have to pay it, as it sounds like the first owners didn't. So, have a look at the property, if there are other newer properties around, that the owners know where the flood level was (around here, they stick a red plastic ribbon on a tree, I just remember which knot of the tree the ribbon was on) and that would show you your true level of flood risk. locals will also know if new flood canals have been built to change the flood behaviors--city hall would be up to date on that. Other than that, yep, flood insurance is a thing we deal with.
