Deposit amounts for commercial properties vary. Most property managers will ask for the equivalent of about one to two months of the rent amount. The amount charged often varies by the market, tenant's credit and the cost of improvements (or custom alterations) before occupying. For the most part, the owner of the property typically will want to be able to cover potential losses if the tenant defaults or damages the property. Some may even choose to charge as much as six times the rent for the deposit in certain markets. Unlike residential leases, there are often no legal limitations on what can be charged for the deposit.
