Hi Andrew,
I don't know of many franchises that will allow you to work out of a home office. When I was looking into purchasing a franchise I did not find a single one that allowed it. (I didn't research every single franchise either - so it doesn't mean it isn't possible).
Sign up for as many franchise offering circulars as you can and see what makes sense.
My franchise fee was worth every penny I paid. Be sure you choose one with a lot of resources available to you (great things are access to free graphic design, attorney services, etc).
Good luck!
