Jota took the words out of my mouth. I'm going to guess there would be no disclosures which first scares me because you have no idea what type of condition the house is in. And before you even place a bid you'd have to pay for an inspection on the house. Who knows how old the furnace is, the roof, the electrical? Just alot of things could be wrong with it. Many houses on auction also need work done to the property so think of the money that you "think" you might be saving will have to come out of your own pocket to update. Also, think financing. Mortgage companies will require an appraiser to go out and have all repairs completed before closing (which the seller has to pay for most mortgages but you could probably find some creative financing somewhere). So if you are buying with cash you won't have issues, if you are buying with a mortgage, then you will have issues (if repairs are needed).
