A question from Yahoo! Answers:
Is there a real home based business that works?
Of course there is. Almost any small business that is normally done from an office (as opposed to a shop or a store) can be done from home. Accounting, bookkeeping, consulting, graphic design, law, medical billing, and software development are just a few examples. A few years ago, The Wall Street Journal profiled a man who runs a mutual fund out of his house (when SEC auditors show up for annual inspections, they work at his kitchen table).
The real question is, what skills do you have?
