Hypothetically yes, BUT:
(1) As a Real Estate Professional the final result won't really matter (it can matter if you are not a Real Estate Professional due to Passive Loss rules).
(2) If you do that, then the program will think the vehicle is less than 50%, which may cause problems (I would need to review the rules, but I think the requirement for over 50% business usage to get accelerated depreciation also applies to vehicles over 6000 pounds). I suppose you could enter it all under one property, then make adjustments elsewhere to spread out the deduction among the 5 properties.
