I emphasize that word reasonable because it shows up a lot in the Texas Property Code.Be sure to keep all the receipts for expenses and an accurate log of your time.

Keep a log of every interaction.

I need to screen my tenant online in a way that doesn't require her to have a computer or log in for anything.
