You'll probably have to keep your own records of depreciation because TTX won't do that for you when you keep taking rentals out of service and putting them back into service.
When you take a rental out of service for, say, personal use, and then put it back into service as a rental depreciation starts all over again for 27.5 years BUT AT A LOWER BASIS to take into account the accumulated depreciation. This is a pain but it's the way it goes when you put the rental back into service.
