There's always a little bit of uncertainty with house hunting. You may be afraid you're going to inadvertently end up with something that needs a major overhaul. Sellers are not allowed to encourage your purchase under false pretenses. If there is something seriously wrong with the house, they must let you know or they could end up with a lawsuit on their hands. These issues are typically revealed in a disclosure form, which the seller must fill out and make available to the buyer, but that can sometimes be complicated to read, so you can always just ask the seller in person. Here's what you need to know.
