$1350 should I do return or keep

[Mark Suliman]

Hi BiggerPockets I need your thoughts on this situation, I have a  tenant in sfh (good tenant always on time with payment ) his lease was up November 30, the lease has a month to month clause, and 60 days written notice to terminate the lease, he called me on December 4th to pick up the keys I ask him why he did not give me a notice as the lease states, his answer was that on October 25 when I came for inspection he told me that he will be moving out, i was  surprise for him to tell me that, his deposit $1350 is he  entitled to have it back,
