HELP!!! foreclosure

Help! Someone came to me that heard that we are Real Estate Investors. She said that her husband (whom she will be divorcing) has not paid the mortgage for a few years and is going in foreclosure. Her name appears on the house, so her credit will be the one affected & not her soon to be ex-husband and they've owned the house for about 25 years. Here's the thing...she must have refinanced over & over because she owes $305,000 & the zestimate is only $220,000, although I know that in that area of town we could get much more, not $305,000 though. I know Dean has talked about how he has helped people in this situation. Dean, are you out there??? Please help!! I really feel like I could help her if I knew how to finangle the numbers right.
Thanks!!!! mary
