How to fund Seller finance and Subto Properties

[Luis Herna]

When in a Seller financing deals (with subto - hybrid) asked you to put some down payment and there is not other way to close a deal with him, where we can find private money for the down payment?  Are there private money people just for this deals?. Can you use this same property as the collateral for the lender? I can overcome Due on sale clause, I can over come debt-to-incomve ratio, I can create a LP to share equity with lender. Any suggestion people?
