buying flooded property with new walls. Anything i need to know?

[Tuan Dang]

Hi Guys, 

I am looking to purchase my first flooded property. I have found one that looks good for a buy and hold situation. They have already put up new walls do i need to ask anything like proof of no mold prior to putting up new walls or anything? Not sure if that is something my future buyer would ask me so any information regarding what questions i need to ask would be appreciated.
