I am debating if I should take depreciation on my personal home onto my federal schedule C.
Let me explain, My gut feeling tells me that when I eventually sell my personal home I will be forced to add back all the depreciation I have taken on my schedule C for all those past years as income for when I sell the personal house. To a lesser extent, I am concerned about those blasted potential audits by the IRS, which I rather not have.
I already allocate a portion of my real estate taxes, but do I have to do the depreciation ?

No, you do not HAVE to do the depreciation. That is unusual, but it is an option on Business Use of the Home.
