Thanks. I agree Walt, that would fix the problem. I am considering doing that. MIL has lived in the house since 1970 and, although it's a piece of crap, she's going to be reluctant to leave it, I think.
I also didn't mention that there are tons of steps in the house (split level) and she just had knee replacement so I might be able to convince her on that basis.
I do appreciate your feedback!
