Does the co-borrower non-occupant name have to be on deed for fannie mae?

Yes

Yes. It is required, since they become a co-mortgagor.

I am assuming you are looking specifically at a fannie mae purchase loan and yes the non-occupant co-borrower must also be included on the deed.

As others have stated.. yes.. all borrowers are required to be listed on the deed.. no exceptions.. I'm a Broker here in Scottsdale AZ and I only lend in Arizona.

Absolutely 100% yes... If they are on the loan, they go in title.
