The Sheriff does not guarantee or warrant, in any way, the real estate upon which you are bidding. He is merely following the request of the plaintiffs and selling whatever interest the defendants might have in the various properties. It is advisable for you or your attorney to determine what that interest is, before you buy. The defendant might not own the property at all. Some other person may own it or there might be mortgages or liens against it that you may be required to pay before you obtain a clear title. All these factors are for you to determine. The Sheriff has not and cannot make these determinations for you. Once you have bought whatever interest the defendant has, if any, you may be required to pay that sum of money to the Sheriff regardless of what you later find out about the title. You should know what you are bidding on before you bid, not after.
