Getting a mortgage is a complicated process. There are two parties involved in making them happen, and it can be a little confusing when reading the legal documents and determining who is who. Basically, it boils down to you (the mortgagee) and your lender, which is probably a bank or a broker (the mortgagor). Check out this post by Rowlett Real Estate School at Active Rain for more info:
The mortgagor owns the property, and the mortgagee owns the mortgage. A mortgage is regarded as an investment or chattel (personal property) by the mortgagee and, like other such investments, may be sold to another investor if desired
