Private lender down payment and DSCR loan

[Micah Grant]

My wife and have just purchased our first two investment properties with traditional financing and capital. We will be looking at a large multi family unit this weekend but would need about 139,000 for the down payment on 695,000 (purchase price). If I were to bring in a private lender for the down payment on a DSCR loan is it possible to get more than the amount needed financed to pay the lender back. In addition, do most private money lenders charge a percentage based on amount borrowed. Based on the income and expenditures The ratio is projected to be 1.65. Thanks!
