why not sell their home rather than face foreclosure suit ?

[Lucky B.]

It just occurred to me and i am sure there are many reason for not hurrying up to sell a home even if equity exists when facing a foreclosure suit. 

i am about to buy a home at the county auction, and the home is worth 300k and the judgement amount is 190k. why didn't the homeowner hire a realtor, and sell the home instead of losing all the equity in the foreclosure process. is it a lack of knowledge , a problem with the home itself, ignorance or they don't want to be bothered with the stress until the sheriff comes to escort them out the house ??
