Home Office Deduction - Mileage

[Nathan S.]

Hi BP world, I am currently not taking a home office deduction since the entire space I use in my primary residence for my rental business is also used for personal activities (computer, file cabinet, office desk).  Am I still able to consider my primary residence as a home office for purposes of mileage deduction to and from my rental properties and any errands involved in the business?

It is the primary place I conduct rental business and Nolo's Every Landlords Tax Deduction Guide seems to elude that I can get the mileage deduction.
