End of lease cleaning or End-of-tenancy cleaning is a deep cleaning procedure performed at the property before a tenant moves out. When you rent an apartment or a house, you look for its cleanliness. Likewise, when you vacate a home as a tenant, your landlord expects you to handover the house in a good condition. Many landlords require a security deposit in their rental agreements. The security deposit is some amount of money collected and withheld by landlords from the tenants until the end of leasing.
