In order for it to make financial sense, the increase in income would have to be enough to cover the mortgage payment, power, trash, insurance, phone (assuming you want one), internet connection, electricity, office employee salary, office supplies, and other things like a refrigerator or stove if you want a small lunch room.

That's a pretty big jump from working in a garage or extra bedroom. I know exactly what you mean about working from home. I can never study at home because if my wife sees me sitting at my computer, she naturally assumes I'm goofing off, or thinks what I'm doing isn't as important as taking out the trash, changing our daughter's diaper, etc.

She doesn't realize that the reason I can pay all of our bills is because I am constantly required to update my knowledge and certifications.

And other than my wife giving me honey-do's, I also have the temptation of cable tv, taking a nap in my bed, and a host of other things.

I always study best in a coffee shop with a laptop and books or in a library.
