I am in the process of studying for my licensing exam in the state of Tennessee and plan to work in the Chattanooga area upon completion of the test (which will be quite soon).

Some towns require licenses, max out the days you can do it, etc. 

Working with house hackers is why I got my license in the first place.

For what it's worth, I'm no longer insurance licensed since I took my practice fee only.

Quote from @Elliot Rosen: Use a licensed and bonded foundation company and keep the invoices, and disclose it to the buyer.

ask them for recent permit pulls in the county and go look them up to verify activity. you can also call the local building department to verify their license and recent activity. if you don't see any run for the hills. 

Report him to your local licensing boards as well as make police reports, even if not a realtor he will get large fines and potentially criminal charges. 

First off they could close a sale and make a commission and secondly failing to do so could cause their license to be suspended or pay a fine. 3.

Hello, congrats on your license.

You've possibly stated in writing that you (may have) violated several laws ie. working as a property manager w/o the proper licenses etc. 2.
