Home Office Deduction

[Josiah Collins]

Hello BP!

I tried searching old posts on this topic and couldn't find a question similar enough to mine. I currently own one rental unit that I manage myself and I'm wondering if I should be able to do a home office deduction. In my house, my wife and I have one room which is the office. She has a little desk for doing her work/school work and I have my desk. Anything I'm doing related to our rental and looking for the next deal is done there. 

However, I use this computer for recreation too, such as video games. I just bought this desktop PC July 2017 as well, and I have a laptop that I use too. Even if I can't claim this deduction in 2017, going forward I'm wondering what we need to do in order to get this deduction. Would love some BP input! I'm working with a CPA and getting his advice as well, but I wanted to get advice here too because I've had a great experience here and have received a lot of useful advice. I understand that the chances of getting audited are minimal, but I wanted to make sure I can defend/substantiate any deductions just in case! Thank you!
