Flood Zone- to Wholesale or not to Wholesale

My town just had a flood and I see properties popping up on the MLS for sale in the flood zone (5+) so far. This is a nice neighborhood with 3bed/2bath/2car garage homes. The homes all need half the walls removed, floors redone, mold remediation, etc.  I understand insurance prices in a flood zone are higher. The questions I have are:

1. Investors, how much below market value would you need this home to be at to get your attention? 

2. Do investors want to buy homes in flood zones?

3. What wholesale strategy would you use? Or do you leave it alone?

Thanks for the feedback. This is my first time investigation the opportunity of a flood zone neighborhood.
