Composition in service supply

A person is a doctor having exempt supply under GST. His turnover is 30 lakh per year. He also gets commercial rent from a building which is one lakh per annum. Therefore he has taken a GST number and files monthly returns for commercial rent. Will he qualify for the latest composition scheme in service. His turnover is less than 50 lakh. Is there a clause that one with any exempt supply in total turnover, is not eligible for this composition scheme for service.
