Where do you indicate less than 100% business use on schedule e detail so that it calculates the allocated rental expenses?

As in:

1) There are days of personal use of the rental?

or

2) It wasn't available for rent for the whole year?  If this is the case, why wasn't it available?

The devil is in the details...

Or, as in client owns less than 100% of the property?
