The DSCR product is a non-QM loan and will not be sold on the secondary market to Freddie or Fannie, so there are lenders that may will not require a seasoning period. 

Assuming a required rate of return of 5% (comparable to high-yield savings or a CD), the deal would need to yield a total CoC return of 10% (since everything is split 50/50).I'm stuck because while playing around with numbers, achieving this return seems improbable if not unrealistic.

Being on title protects the seller from the buyer defaulting - it seems this is an alternative to "officially" putting them in a 2nd position)-- Title company sends seller the $350K they require-- Title company sends buyer back $650K (which they can use to pay off their transactional lender if they used one)So now the seller is happy bc they got the $350K they needed, the buyer is happy bc they acquired a property for zero dollars out-of-pocket, and from what I understand the 1st position lender is happy bc due the LLC arrangement the seller finance component is not technically considered a second lien on the property.
