I’ve put 3 of my 4 kids thru college and have just finished with my son in law. Him, my daughter and 2 grand kids have been living with me for about 7 years while he was in school. It’s a big house and I’m single, so I don’t mind them here. We all get along and he’s knocking down $70K/year paying me rent & utils.
I would gladly take in my adult children under certain rules....no sleeping on the couch and we all don’t have to do everything together...
