I live in Ohio. I bought an appartment building about a year ago, aparently the previous owner had a tennant evition. The tennant retailiated by plugging all of the drains and turning on the water and sealing the door before shimming down the outside of the building. This flooded the upstairs aparmnent and two below it. The old owner recieved a insurance claim check to fix this which he used a very small amount to touch up the paint and clean the carpet, and pocketed the rest. He did nothing for the water in the walls, a year and a half later now that I own the building the water soaked insulation has attracted mold and i have a huge repair bill coming to me. The way I see it there were three people who should have informed me of this problem before I purchased the building. The old owner should have informed me there was recent flooding(and should have fixed it corectly), The home inspection company who missed water damage, the company who conducted a mold test.
Additional Details
The mold test was conducted because there was a higher humidity level found in a few of the aparments, inspector pointed to window condensation(fog), although he claimed it was from the showers.

Any suggestions or am I Up the creek????????
