Car Expense Tax Write-Off for Real Estate Investor

[David Coffee]

Hey there! As a Real Estate Investor can you write off your Car expenses if you use the car for multiple businesses?

EXAMPLE: You use the car to look for potential flips, business trips and to go to business meetings; BUT you also use the car as a DOOR DASHER on the side.  

Question:  Can the expenses or mileage from the car be written off for both businesses?
