How do you handle turnovers?

[Quintin Mortensen]

I'm newish to investing and I have my first tenant from Salt Lake City, Utah moving out at the end of the month. Just wondering the process you go through to get a new tenant in?

How soon do I advertise? 

Do you try to show the place with old renters still in there?

Is there any process I should avoid or look out for?

Thanks so much in advance for your advice.
