Do you mean will you get clear title in a sheriff's sale if its the first mortgage lender foreclosing?? I'm really not sure what the question is, BUT in any case, the answer is the same.
No. There is no situation in which you can assume clear title. You should always hire a competent title professional - attorney or expert title insurer/agent - to examine title and issue a commitment to insure. The commitment will outline issues and exceptions.
You want title insurance, not just an opinion. Humans make mistakes and that's why you can't assume clear title, ever.
