You may want to have a property inspection before signing anything. If you are aware that work is needed, then an inspection can insure that there are no other problems that are too big to fix. Foundation problems and other items can cost more than you are willing to spend. As is means no recourse.
It depends upon the type of sale you are involved in. A property purchased "as is" at a foreclosure auction may have tax liens or any other issues, and you usually cannot do a home inspection on a foreclosure. With a property listed by a broker "as is," carefully review the home inspection report
'As Is' means completely as is with no warranty of condition. You should get the property inspected by a professional or accept the property's condition willingly before entering a purchase agreement.
You need to be careful when buying property "as is". It basically means that you are buying the property the way that it is. If the house needs repairs or is falling apart you are responsible for fixing it. The seller has no obligation to fix it. Negrita
