This is a bad idea. My brief understanding of the licensing laws regarding debt collection in a couple states is that not being licensed could prevent you from enforcing the debt, but I'm not an expert here. You'd basically be unsecured, and the only true way mitigate risk on unsecured debt is diversification. You'll be completely concentrated in one asset. You'd be better off just investing in one of the many note funds rather than straight-up gambling for a couple hundred extra bps.
In the general environment right now, state regulators are looking for every excuse to go after "real estate investors". Just look at the myriad of laws, regulations, and bans passed or proposed for seller financing, wholesaling, and lending in the past two years. If caught, best case scenario is you'd get a cease and desist letter from the state regulator and probably fined. 0% chance this is worth it. If a license is required and you don't want to be licensed, do business in another state.
A final point - foreclosing is generally a legal process involving attorneys. I suspect you'll have a hard time getting an attorney to assist you in an activity you're engaging in illegally. The is the basis that SC is using to go after wholesalers at the moment - passing a "ban" that's murky at best and then daring the attorneys to test it.
