To the extent the fiduciary does not account for receipts from rental property pursuant to Section 19-3A-403, the fiduciary shall allocate to income an amount received as rent of real or personal property, including an amount received for cancellation or renewal of a lease. An amount received as a refundable deposit, including a security deposit or a deposit that is to be applied as rent for future periods, shall be added to principal and held subject to the terms of the lease and is not available for distribution to a beneficiary until the fiduciary's contractual obligations have been satisfied with respect to that amount.
