Depreciation vs expenses percentages - rental use

[Samuel Kowalsky]

As I work through some of the IRS worksheets, I am wondering whether it is normal that there is a difference in the fraction of depreciation one takes on a rental property that was only rented for part of the year, and for deductible expenses incurred during that same year, if the property was idle for a period of time.

For example, if I rented out an apartment for the first eight months, then the apartment was vacant for the remainder of the year (needed some work that I did not have time for), would I be able to claim 100% of the depreciation, but only 2/3 of the deductible expenses for that year ?

Thanks in advance for your help !
