Real Estate Professional for tax purposes question

I have a question that I am hopeful someone here will know.  For tax purposes, the real estate professional designation is something that is very helpful if you are an investor.  Would a home inspector be able to claim this designation for tax purposes?  I know that property managers such as people running apartment complexes can claim this. However, if an investor was also a home inspector for his primary income, would this qualify him as a real estate professional for tax purposes, thus removing the $25,000 cap for depreciation loses?
