Hello @Sandy Uhlmann. Kansas, unlike, Missouri, is a Judicial State, which means a lot more headaches with foreclosures. You definitely need to speak to a real estate attorney, licensed in Kansas, about your situation. Since you have already spoken to one, I would recommend you get a second opinion just to be safe.
I have never seen a situation where a house was foreclosed on and there was equity left over after the lien holders, taxes, and other expenses were paid. If there was any equity, than the home owners would be crazy not to sell and save themselves from the credit damage of a foreclosure.
Do you have any idea if the home owners are thinking about filing for bankruptcy? If they are going to file a Chapter 7 bankruptcy, you might as well quit now as you won't get a dime. If they do a Chapter 13, you may get some of your money back, but it will not be all of it.
How big is the 2nd lien? Is it big enough to risk paying a few thousand dollars in legal fees to maybe recapture some of it?
