These are the photos taken by the bank prior to Mr Baldwin and his mother purchasing the property. This house was built on a flood plain, and the roof looked to be leaking. Vents in closets are not unusual in closets high humidity is an issue. A flood would explain the dumpster full of discarded furniture, etc. Baldwin's mother said there was so much trash inside the house you could hardly walk around, that is not depicted in these pix...perhaps she was talking about the trailer...unless it had already been moved.
My kid is a realtor and she said the excessive mold would trigger the waiver Baldwin signed (also at link), but they would not show a house, even with a waiver, that had human waste on the floor or walls. You never know though...small towns might look the other way.
In one of the pix you can actually see the hole in the water damaged ceiling.
