A 12 month lease contract with my tenant states I will return his $1600 deposit within 30 days after the lease expires, if he decides not to sign another year's lease. He has verbally informed me I should keep the deposit as payment for the 11th month he is in the rental, because I would not be receiving a rental check for the last month. Says he needs to use the $1600 deposit to move, and I should use the money for the last month's rent. He has been a great renter, but that's not the issue. Anything I can do? Thanks very much for responding.
