I did some research after this nearly happened to me and it is apparently a very common form of mortgage fraud.
I cosigned on a mortgage to help a family member. When I was applying for my own mortgage the first lender I spoke to told me to claim the home I was cosigned on as my primary residence. I made it very clear to the lender that I do not live there and would not ever live there but she insisted it needed to happen. I got a second opinion who flat out told me that's fraud.
I have a red prius named Lobstah and a Nissan names Paul.
