Buying a house, other than new, is like buying a used car. If you rely on the seller to disclose all negatives, you are one of those people P. T. Barnum spoke of. You know, a sucker being born every minute.
To be as safe in your purchase as is possible, get it inspected by someone who has been a building inspector, general building contractor, or equal. His responsibility is to you.
From what I see in the disclosure statement signed by both seller and agent it's one of those "you lie and I'll swear to it," deals.
It is still "buyer beware." Get it inspected.
