Hello Deborah, Sorry I got in on this topic late. Wish I could say I haven't gone through something similar in my own life. YUK! But, you do what you have to, and, apparently, so does your Mom, all relationship issues and personal problems aside for the moment.
My thoughts head in a slightly different direction based on how you te'ed up the issue, then commented later on in the string:
1. Clean up, stage, then sell the house. Keep in mind that she may not have near the equity she thinks, because the most likely buyer will not be your choice, best buyer. In other words, it'll be someone like me who has to generate a profit from sale, or buy low to help fund rehab in order to rent and generate cash-flow.
2. Maintain min payments on the CC debt till further notice (see below).
3. After house is sold, using current income from job/SS, rent cheap room or studio apt if possible (just recall that one qualifying criterion among many are that new tenant must have income 3X the rent - this is my first qualifier). To assist, perhaps she has a friend who will move in with her to offset expenses?
4. After executing on the above, if your Mom is still insolvent (legal definition speak), file BK and wipe out unaffordable CC debt. PLEASE KNOW THAT I AM NOT A PROPONENT OF STIFFING MY CREDITORS, BUT AT SOME POINT, ON SOME LEVEL, BEING ABLE TO LIVE AND FEED MYSELF, THEREBY TAKING CARE OF BASIC NEEDS, BECOMES MORE IMPORTANT THAN NOT PAYING THE CC BILLS.
5. Assuming no other options existed, once BK is discharged, begin drawing from 401-K, or from regular IRA created by a roll-over from 401-K, as needed to supplement SS income (assuming she has already quit her job).
As alluded above, my bullet item 4 above may annoy some of my fellow investors and agents, but in the absence of more income, or willingness and ability from the kids involved, or other viable options, it is what it is.
Best of luck to you and your Mom.
