Can I get home owner tax credit for a house that I am buying from the owner with no banks involved? I pay them a monthly mortgage payment until balance is paid off.

there is no home owner tax credit at the federal level, so are you referring to something else.  

If you're referring to deducting mortgage interest paid to an individual (private) loan, the answer is yes.  You'll need identifying info (SSN) from the individual that holds your mortgage to report that you're paying them.

However, using mortgage interest as a deduction requires itemizing your deductions using Schedule A.  Since the tax law changes took effect, the standard deductions have increased significantly.  You may not need to itemize your deductions after all.
