Just got into this thread and am many pages behind.... but, sounds like a complete disaster....
Looking at your RE issue, good intentions going bad... never should have put her name on it....
We just bought my MIL a new place... we had to get it in her name to begin with, but DW went to her this summer and had the property transferred to her name... we own it 100%.... yes, we can kick out mom at any time..... do not plan on doing it, but if my financial situation was as bad as yours I would.... but I would pay her back the % of funds she put into it.... it was not all our funds....
Yeah I know I shouldn't have but I did.
I'm just a big sucker what can I tell ya.
