How do you know when it's time to move your business out of your home and into a "real" office? Bob Horgan put off the decision for so long that he eventually had more than 40 people working out of his home. "I knew it was time to move," says the CEO and founder of Newmarket Software, which today houses its 130 employees in commercial space in Portsmouth, N.H., "when we had someone else's desk in my bedroom."

Not Home. Not Alone.

One woman we know got more than she bargained for when she moved her business from her home into an office in another building, which had a residential tenant living upstairs. First, the office was flooded when the tenant improperly installed a hot-water heater. Then the same tenant threw a party, in the midst of which gunfire began to echo throughout the building. But it was when she discovered that the tenant slept in a coffin and answered only to the name "Satan" that the otherwise-intrepid owner concluded there is, after all, no place like home -- which is where her business is currently located.
