Sheryl, I'm so sorry. I'm sending wishes for comfort. May it lead to some better solution. Things can't really keep going the way they have been, for all of your family.
Sophia, decisions like this are exactly the kind you need to take your time with. I agree that a house inspection is a good idea. We did this prior to putting the house on the market to get a punch list of what needed to be done.
askye, I hope they get to the source of your mom's issue quickly.
