I,m looking at a forclosure home. There is some yellow spots on the ceiling mostly in the master bath all over. Some small spots through out the upper level of home one spot in the kitchen and a repair done or patch up of one small section of a wall in the living room.There is also some holes in the ceilings. The spot in the kitchen was patched up in that ceiling. And also, the wood laminate flooring has a few noticeable bumps near the damaged areas. What do you think is the problem? Is there a possibility of mold? What I need to do? This is my first home I purchased. Need good advise.
