^I am guessing his new plan is for his parents to die and he inherits the house!
sad to say I think that is how most people are planning to fund their retirement
He's an only child: I suggested to him that since his parents haven't had a mortgage on their home for decades, to have them put up the down payment on a multi-family (or even a SFD with a suite) as an investment. Their wealth isn't going to anyone else. He said that he's not comfortable with that...just before he finished his coffee and grabbed the bus back to his childhood home.
