The particular house you referred to is a possible foreclosure. The whole foreclosure process takes some time and first the lender files a Notice of Default. That property probably had a public notice filed. Before the foreclosure can occur, the lender then has to file a Notice of Trustee Sale about 30 days afterwards.
In the meantime the borrower may bring his account current and the foreclosure never happens, but the Notice of Default remains on the record.
There are two more houses in Rockwall/Heath that might interest you because they fall in the same pricing scheme.
