My mother was recently removed from her home that she was sharing with my brother, because the house was covered in filth from my brother's 24 dogs (dog hoarding) Long story short, she is currently living with me. She needs extensive dental work and would be best off in an Assisted Living situation. The house was purchased for $170,000 12 years ago. The current mortgage left is $100,000k. The market shows a possible value of $175,000 but the house needs at least $20K worth of work. Do we take her savings (not a large amount of savings) and fix the house and hope it sells (in a year or more)? Or, do we walk away and use her money to fix her teeth and find a nice place to live NOW?
