Expenses related to preparing to sell Rental Property

Hello,

I rented out a condo for nine months in 2019.  It was empty for three months.  I spent just over $2000 preparing to sell it (plumber, garage door repair, dishwasher repair, paint, carpet cleaning service, etc.).    I spent the money in 2019.  The original buyer fell through.  We have a new buyer and expect to close in February.   Do I deduct these expenses in 2019?  Somehow increase the basis of the unit?   Or hold the expenses and deduct them in 2020?    

Thank you.
