Should I repair the pool on my rental property/primary residence if I am planning on selling with the next couple of year? What tax deductions apply? Is it beneficial?

The pool was in disarray when I bought the property.  The property is my private residence and the rental includes a room and shared usage of the rest of the property.  I was considering repairing the pool to help sell it in the future but don't know it it will be beneficial or a detriment due to the tax implications.  Can it be expensed as repairs to the rental property?
