Seller Financing a BRRRR property

[Christian Thompson]

If the seller still owes on a property, do they need to pay off that loan before owner financing? 

The current deal I'm looking at is 3 duplexes. They need about 70k worth of repairs to bring them up to value. The owner is willing to do owner financing, but still owes a few hundred grand on the property. Is there a way for the to owner finance this deal without paying off his loan?
