I'm not sure of the laws in your state, so don't take my advice without consulting a lawyer. Here in Las Vegas, with a situation like that, I would advise someone in that position to live in the condo as long as possible without making payments. It would take the bank over 2 years to get serious about foreclosure. Then, you could negotiate making a short sale. Add about 6 months until you are out.
Have her save the money she would have paid for the mortgage and use it to get a new place. It would make be enough for a down payment for the same type of condo in the same development. Total payment for the "new" place would be under $1k a month PITI for a 15 year note. You, or another family member would have to cosign, or even take out the loan. If that's not an option, then renting might be.
What hasn't been mentioned is her current financial status. Her income hasn't been enough to support that place for quite some time. If she has a lot of consumer debt (credit cards, signature loans, HELOC or second mortgage) then bankruptcy might be in order.
What I would advise against is selling the home and making up the difference, or her borrowing (even from family) to continue to make those high payments.
