Alt Lender / Private Lender Options (USA)?

We service###-###-#### buyers at any point in time as a buy-side where it's primarily SBA deals (typical mandate is between $250k and $1.2M EBITDA). We generally go down the path of SBA, but for some the industry or structure sometimes throws things off.

We'd love to have alternative options, interest rate usually isn't an issue even much over SBA level given our DSCR is always quite high. For example here's a deal we had some issue with the SBA on due to industry:

Performance marketing agency
$6M EV (4.4x ebitda)
$1.34M ebitda 2024
56% SBA loan ($3.35M)
44% Seller note ($2.65M) on SBA standard (2 year standby, 10 year term)
2.3x DSCR
