Owner Occupied Commercial Building - Partial Lease Reporting

I own a building with two relatively equal spaces.  One portion is used by my laundromat and the other portion is leased as a restaurant.  The lease to the restaurant accounts for about 25% of the total income from the property.  Since getting flagged for audit due to my operating numbers not being consistent with a leased laundromat operation, I have been reporting rent paid to myself and rent collected from the restaurant along with all the building expenses on a Schedule E.  Can I just report everything on my Schedule C?  The main reason for wanting to do this is to claim the income as active income for SEP contribution purposes.  
Thank you.
