Taxes - Lowes and Home Depot Receipts

[Dan D.]

I am getting prepared for taxes and I'm reviewing many of my expenses for a property in the last year.

Do I need to categorize my home depot and Lowes expenses based on whether the item was purchased was used for a repair, such as painting something, or an improvement, such as backsplash tile?

Or since I was rehabbing the whole house prior to renters moving in, does it count all as improvements?

Also, how about the purchase of tools?

Sanders / paint brushes?

Thanks in advance!
