Realty Trac does not list properties FOR SALE, the only monitor DFAULTS ON LOANS. As the website states; "Notice of Default. This property has started the foreclosure process because a loan secured by the property is in default. The borrower/homeowner still has the opportunity to stop the foreclosure by catching up on defaulted payments or paying off the entire loan balance usually by refinancing or selling the property."
The answer is yes liveable, most likely the current owners still live there, but the property is not for sale!
