Can a R. Estate agent renting own condo for 245 days in 2018 claim a loss? TT is allocating all expenses so that they equal income. Not just interest and taxes.

If I input 365 years on the system and allocate the expenses manually, I can get a loss.  But if I put 245 days in, I cannot as expenses are always matching income, which makes no sense because I'm a Real Estate agent.
