owner financing

[Jerrell Slay]

i currently have interest in a package deal, the deal is 3 houses in the urban side of town the owner wants 33.5k for each or 75k for all 3 houses, 2 houses have tenants  which pay roughly 900. The owner stated he would like to do the deal the traditional way and sort of shied away from the owner finance. Me and my wife have work to do on our credit and owner financing would be perfect for us to do. ( we definitely have people we know that would rent the properties so that is not an issue). Can anyone give me some advice on how I may be able to convince the owner the benefits of owner financing? Thanks to all
