Do you want to claim him as a dependent on your tax return? He has to live with you all year and have less than $4,200 total income and pay less than half of his own support. Does he have income? If not how did he qualify for the mortgage? And the lender would have needed to see his tax returns.

You can enter any mortgage interest and property taxes paid on your tax return as itemized deduction on Schedule A as long as you are on the deed as an owner and you are on the mortgage as one of the borrower's.
You do not enter anything on your tax return concerning him.
