PIB TIP: UNDERSTAND ESCROW ACCOUNTS. Lease purchase agreements often require an initial security escrow of $1,000 to cover expenses the lessee may fail to pay. Maintenance escrows, which are funded throughout the length of the lease-purchase, usually are required. A lease contract should state the precise purpose of escrows and that all unused escrows should be returned with interest at the end of a lease.
