buying flooded house, must raise?

[Rachel Lang]

So my husband are considering buying a Harvey flooded house as our first live in flip. We are seeing great deals on the market and want to buy something that flooded for the first time in Hurricane Harvey. But, I am hearing rumors about FEMA requiring people to raise the house to a certain elevation before they are allowed to renovate. Does anyone have experience with buying flood houses? How would we find out if FEMA is requiring this before buying a home?
