"Our rental building"? Who's "we"? Is there another member of the LLC besides you? Are you or have you been filing a 1065 for the LLC if it's been treated as a partnership...and that's the default for more than one member.
Rental income is usually passive and you don't take a "draw".......you report it on Sch E if you're filing a 1040 or form 8825 if you have a partnership.
