Mileage deduction average per year for rentals

[Simon Martinez]

So I have 12000 miles that I kept track of for going on trips to the store/to see tenants/ ect for this tax year of 2018.

My concern is is that too many miles that could trigger a audit? I have 9 rental properties that I visit from time to time and I go to Home Depot often.

I was wondering if some other rental property owners could share how many miles they have deducted in the past.
