One thing to remember, if using you home as a office, you are depreciating your house.
When I first started I lived with my girlfriend (now wife) who owned a home. I rented a room for an office. Also payed some of utility bills. When we sold the house, we had to pay taxes on the years of me doing this. Big surprise. You depreciate your house when you use it for work/office and show IRS. I currently work out of my new house. Erected a building in the back for the shop. But I do not show Gov. any payment towards office or building for business. It depreciates the property. In my case it is worth it for me to just pay bills as homeowner.
I would suggest talking to your accountant!
