​Secondary Market for SMB Loans

Hi guys, sorry if this is a dumb question, but outside of the SBA, is there a secondary market for private small business loans?

I work a B2B sales gig leasing equipment to businesses. Customer signs for x per month, and we sell the stream to the finance company, and get our commissions paid out of that. The lease is collateralized by the equipment.

The grass is always greener, but in the bullpen sometimes we joke about how it seems easier to be a mortgage broker, “selling money” compared to our products. We also joke about how some of our customers aren’t the brightest individuals.

This begs the question, is there a secondary market for business debt? Could I get an LLC credit approved for a loan the same way they qualify for an equipment lease, bump up the payment a few extra dollars, and sell the paper to a third party? I’m sure the terms would be less favorable without the equipment as collateral, but it’d also be a lot easier to “sell money” than equipment. Have no idea if this is a dumb idea but any insight would be appreciated.
