How can I Pursue this property?

[Anthony C]

I am following a property that was briefly for sale and then owner walked away from and stopped making payments on. She will not negotiate with anyone any longer and has vacated the property and left town. The property as much as I can find is lis pendens but the owner's listing agent also does not want to deal with the property and has moved on and doesn't return calls.

How can I pursue this property? Go to the courthouse and find the creditor? What exactly do I ask for if that is the case?

Thanks!
