SBA Loan Investing

Does anyone have any experience with investing in the government guaranteed portion of SBA loans - either direct or through a pool? I could see this area picking up in 2021 with the SBA increasing the guarantee to 90%. Where would one even go to get started in this area?

I manage an institutional FI portfolio and buy SBA pools. What specifically would you like to know? Loan types are either working capital, machinery & equipment, or real estate. They are floating rate, indexed to prime, and reset quarterly. Prices are high and yields are low right now.
