another mold question

[Chris C.]

looking at a very nice foreclosure by me price is $65000 local comps are 180-215000 the house is 3 bed 2.5 bath 2100 sq ft built 1990s been empty for over 2 years with a flooded basement which is all cement walls, but rest of the inside of the house mostly the walls which is painted drywall has mold anyway to know if this is wipe off mold or drywall would need gutted and replaced? What would something this size typically cost? Its a 2 story house main problems is on the main floor but sure some has made it upstairs
