Could you please help clarify this question:

Eric lives in a home with a six-plex located at the rear of the property. On his tax returns, he allocates 60% of all expenses to the apartment building. He is getting really tired of dealing with 6 tenants, and is seriously thinking of moving in with his girlfriend. Eric inherited the property from his parents two years ago. It was worth $600,000 then, and $1 million now. What are Eric's options?
