ok i live in Trenton NJ i live at the end of a row and have a condemned garage with 4bays the one has a old well that was covered with a large concrete slab and the other 3 are dirt floor. all the wood is fuzzy with mold, and or falling down. i want to move soon but i don't know if i have to fix it so it is safe to use i have 4x4 on cinder blocks hold up the roof now, will "as is" let me sell it like that or does it have to be livable/ functional/ safe?? or do i have to leval it out and pour concrete down so it is functional space??
