Best ways to track mileage?

[Brett Loetz]

I currently have one rental property and am in the middle of my first Brrrr, I’m doing most the rehab work myself on the house so I have a lot of driving back and forth to the property, and also to the local supply stores. I’m wondering what the best way to keep track of my mileage is. Last year for my rental, I didn’t have to much so the old pen and paper worked fine. Just looking for better ideas for now and as I start to grow my portfolio. My accountant mentioned MileIQ, is anyone using that app? Thanks for any advice.
