Tenant skipping out on last months rent. Your suggestions?

My tenant recently informed me that he is moving out. The lease ends at the end of the month. So far, our cooperation has been exemplary. No issues. Money on time.

However, the tenant seems to have decided that he will not pay for the last month and will thus collect the deposit (one months worth). I intend to verify today later today. At this time he is 2 days late.

The apartment is most likely in good condition, if nothing has changed since my visit 4 months ago. However, I prefer to settle the deposit on my terms (lease says deposit refund within 7 days). I usually settle it on the spot when I collect the keys. I think that maybe the tenant contributed to some damage and wants to save himself a few hundred $.

What do you suggest? I am open to ideas. An unannounced visit for coffee is definitely an option.

What has worked for you in cases like that?

Please note, the property has been paid off, and I do have reserves in place. This is an A- area in a major city. Where I invest getting a judgment is not an issue, and this is not a broke tenant I'm dealing with.
