Custody companies need to file with the government to carry out custody business.

House trusteeship is a process in which the owner of the house property transfers the right to use the house to the house business unit in the form of contract, and the house business unit commercializes the right to use the house again, including daily management and lease, and bears the risk of vacant intermediate houses. The owner (or client) entrusts the house to the trustee and signs the entrustment contract, and the trustee will find a tenant for him according to the agreement of the owner.
