Adding Son to My Mortgage

[Account Closed]

I currently own a rental home that still has about $60k on the mortgage (off $100k) value; I'd like to add my son's name to the mortgage so that he might be able to use some of the equity on a payment for his own home. (Is that even possible?) So my main question is: Can I add him to the mortgage without refinancing? Does he have to then qualify for the mortgage as well?
