On how good a terms are you with your neighbors? They might not like people showwing up all the time at your home. Depending on where you live, an at home shop(of any kind) where the customer comes to you can be a no-no.
This is personal experience: You do not want customers to know your address or personal phone number. I have had one of the few customers that knows where I live show up at my house at 9 in the evening wanting something looked at. If you have your business at home you will get no rest once people figure out where you are.
