How to structure/payback investors rehab money on a sub2 deal

[Jeromy Jordan]

Hey BP,

I have a sub2 deal and I'm bringing in private money to fund the rehab.  I plan to keep the property as a buy and hold. I just cant figure out how to structure a deal with the private money lenders to repay their money.  If I were flipping the property, I could easily pay them from the profit but how would I pay them back if I plan to keep the property with the existing mortgage in place from the seller.  Any recommendations?
