Tenant move-out / move-in timeline

[Jeremy Fields]

I've been fortunate enough to have the same renters since I started investing in long-term rentals several years ago. I've come to the point where one of my tenants is ready to leave. I have new tenants ready to sign a lease. I'd like to get some feedback on the timeline between move-out and move-in.

The place has been kept in basically the same condition and I've been working on some updates and minor repairs once the 60 day notification came in. At this point it looks like everything must be handled on the 31st (move-out day), before the 1st (move-in day of new tenant) unless my upcoming tenants agree to allow me in for certain repairs/upgrades. 

How do others handle this transition? Leave a few days between move-out and move-in? Suppose the former tenant does not completely vacate? Then what?
