How do I report expenses related to fixing up my property to rent?

We purchased a single unit rental property in November 2017. 
We made repairs, painted it, installed window coverings, put in washer/dryer, and paid utilities while preparing it to be rented. We began advertising the unit for rent in April 2018. 
How do I properly categorize the expenses we incurred while preparing our unit to rent?
Also, we did not rent the unit until September 2018. How do I categorize expenses incurred while advertising the property for rent, but while it was still vacant.
Thank you!
