Investors & landlords

Right, I think there might be some confusion here. I never put it on a payment plan or credit card, I just paid half of the bill in 2019 and half in 2020. And since I am directly paying the contractor, that is when they are getting paid. 

 

Since the window would be an improvement, I'm assuming I can take the cost of the actual wood rot repair (materials and labor) and mark that portion down as a repair expense? Or does the whole bill have to go towards capitalized and depreciated just because a portion of the work ended up being an improvement?
