Rental property: repairs and renovations question

I paid a contractor around $25,000 for repairs  and renovations to get my  property in shape to rent. The work started in late 2017 and was completed in May 2019, and the property was rented soon after.  Because the contractor didn't itemize most costs,  I don't know how to separate the repairs from the improvements for tax purposes.

  • Does the cost of interior painting, which was done as part of the whole project, need to be separated out as a repair, and is there a way to do that without an itemized invoice? 
  • The new flooring had to be replaced in one room after just a few months, before the property was even rented. Would I be correct in including this cost as a repair?
