Or...even if the borrower only got one loan, he may have borrowed against his home equity to finance certain expenses like remodeling.
In this case, the link you provided said that "The estimated original principal balance of the loan in default". Since this is the remaining balance, sounds like the owner has significant equity in the property and may be doing his best to resolve his delinquency. And even if he is foreclosed, please don't expect that the $$ you see is what the price would be to buy this house because the foreclosing bank will want to list this for sale as close as possible to market value.
It is not known from this link if there are other liens against the property in the form of a second loan, or even mechanics lien filed by unpaid vendors who want to collect what is owed.
If the property is sold in a short sale, typically, the primary lender is paid first (in addition to paying off unpaid taxes). Then the primary lender can offer to pay off the junior lenders a fraction of what is still owed to them.
In a foreclosure, the primary lender doesn't pay off any junior liens ...just the unpaid taxes.
