Feng Xu, 43, was arrested as part of a major investigation into modern slavery and human trafficking on 14 May.
Officers raided his address in Holliday Street, Birmingham and recovered one computer database that listed 446 different addresses which he had been involved in renting.
Investigators found evidence Xu had used multiple false identities to source hundreds of properties
31 different false or fraudulent Chinese or Portuguese passports were found, along with numerous ID documents.
The National Crime Agency say the properties were used as brothels, while others were turned into cannabis farms.

Xu is due to be sentenced on 22 November.
