Yes. If a landlord wants a bit more security when renting out to a tenant who has only recently started a business, then the landlord can charge a rent deposit. Commonly, this is a 3-6 month charge of rent paid upfront once the lease is signed along with the standard rent. The landlord then holds onto that money and is only used when the tenant does not pay rent for a certain period. The tenant will then have to add to the deposit with the amount of money that they did not originally pay (plus interest). Once the lease has been completed, the tenant will receive their money from the deposit.
