I did try using the "Owner-Occupied Rentals" portion of the Sch E worksheet, but then it wants to apply that same percentage to all of the direct expenses as well.  And for some reason, if I change the percentage in column (b) for a particular expense, the worksheet completely ignores this override and always post the column (c) amount based on the percentage in the column (b) header - not what I indicate in column (b) for the individual expense.
