I understand that means paying the right professional for their services. 

Is this something I should hire a lawyer/other professional for or can I just do it myself? 

It’s worth a look see, just do your homework up front before hiring the other professionals to make this happen.Good luck

Had a call with someone from their team recently - very professional and knowledgeable. 

Your profile mentions that you are an agent with rentals.You would want to see if you are able to claim real estate professional status.If you are able to claim real estate professional status, you can potentially offset the rental losses with your real estate agent income.Furthermore, TN does not have a state income tax allowing you to be more open with your options.Best of luck
