Can I write off my mileage, cell phone bill, travel expenses, etc.

I think if I could get the property for $20k (lol, fat chance) it would be worth it. 

Your expenses can include any office or transportation expense like postage, internet, cell phone etc.Don't forget to correctly determine the basis of your property and take appropriate depreciation as well. 

Take pix with your cell phone of every room, all the beds in there. 

Insurance companies have started to Cancel policies because the Home Owner installed Solar Cells on the roof.

Especially with Intel coming to Columbus as well as Hyperion, which is a company that makes hydrogen fuel cells.

I would also say the cell phone cameras like arlo have a delay.

A class will teach you basic skills of how to use excel, how to create and input formulas that can carry over throughout cells and sheets, how to create pivot tables and sensitivity analyses, so you don't have to manually redo your work time and time again.  

This thread wouldn't let me include my cell or email but lookup our company at 1SouthRentals.com and contact me thru the contact link.

If you're in a facility where you don't have regular cell phone access can be ameliorated with Google Voice.If you're just getting into real estate I wouldn't recommend it.
