For single family homes, we normally hold to the security deposit and use this as a reserve

For multi-unit properties, we give you any security deposit when we receive it from a new tenant. In order for us to pay on time any bills we agreed to pay , after we have made your payment we suggest you allow us to keep a property reserve so we do not need to wait until the rents are paid the following month, or ask you to send us a payment for a specific bill.
