I agree with Critter. You only enter the days it was ACTUALLY rented. Because you used it for personal use, the days it was available for rent (but not actually rented) are not factored in at all.
As Tagteam pointed out, you need to be careful about which category you use. In Tagteam's example, if you spent $500 for cleaning for both personal and rental use, yes, the program is correct in allocating $250 to rental and $250 to personal. If you spent $500 specifically for rental cleaning, then you need to adjust things. Except for rental-specific categories (such as advertising), most categories are automatically prorated based on the number of days. If I remember correctly, if you enter it as an "other" expense it will use it as a 100% rental expense (such as cleaning costs ONLY for the rental).
