Buyer Carry Back 2nd Position

[Robert Thibault]

Let me be sure I understand.  I have a property where the seller is willing to carry 75% for 10 years.  So, is there any reason I wouldn't want to go get a non-conventional rental loan for 80%.  Then offer the buyer to carry back the 10 or 20% on a carry back loan?  Who do I approach with this first?  Do I need to make sure the seller owns "free and clear"?
