Home Office Deduction on Schedule E

I do not have a schedule C. I owned couple properties and self-managed the properties: collect rent, repairs, maintenance, background check etc.

 

My understanding is home office is put under line 19 – under “Other Expenses” for schedule E per the Curphey vs Commissioner ruling and other research (CPA).

 

1) Does it matter if it’s under the traditional method (home office % of house), not the simplified method ($5 x sqft). Do I need to fill out any other forms?

 

2) Do I put all the home office expenses cost under 1 property or split 50/50?

 

3) Given I declare a qualifying home office (tax home), can I still include mileage expenses to the rentals (maintenance, etc..)
