Do I have to close my unlicensed business in home before selling?

I cut hair in my home and changed my basement into a hair salon. I have one other girl that comes in and we cut men's and some women's hair. We do it all under the table to save money. I am planning to sell my home and move to a bigger house but I want to keep my business going as long as I can. What can i do for listing pictures and tours? Can i keep it up and just say it's a hobby or something?
