Reporting house payments to Credit Bureaus

[Chelsi Howland]

Help!! My husband and I are currently purchasing a home from a personal friend who is going to carry the papers for us. However, we need to know if it's possible, and how, to report our house payments to the credit bureaus so that if we need to refinance in a few years our credit will show the timely, consistent payment.
Can anyone suggest if.how this can be done?
Thanx!!
