What are some common tax write off's?

[Kevin Colwell]

I know the responses to this post should not be taken as tax or legal advise but would the seasoned investors who read this post like to share some of the write off's that they like to use. I am in the process of purchasing my first apt building and the only phone I have is my cell phone so could that be a write off or would I need to have a seperate business line? Any posts would be greatly appreciated.

Kevin
