Real Estate Agent renting own condo- file Sch. E for the inc& exp of the condo, and file Sch. C for other inc & exp of RE biz? Or should all be combined on Sch.C?

Unsure to file both Sch. E and C. Or to combine all income and expenses on Sch. C since I'm an agent working with a brokerage firm with no other job.
