D.P.
I do not do this, but I've thought about it.
I think the pros would be flexible working hours, potential to make nice $$.
I think the largest cons would be that everyone thinks they can do it themselves and everyone thinks their own houses look pretty good, when they couldn't all look good! LOL Kind of like everyone THINKS they've got a sense of humor?
I always thought that partnering with a realtor would be a good place to start.
