What to do with a vacant commercial space downstairs in a 5 plex?

[Chris Collins]

I'm looking at a 5 unit building in Kentucky.  4 apartments upstairs, and a commercial space downstairs which is vacant.

What do you do with a vacant commercial space? 

Place an ad on craigslist? Put a simple 'for lease' sign on it? 

I've never worked with a commercial tenant, let's say a coffee shop wants to go in there, am I supposed to provide anything for the tenant other than an empty space with working utilities?  Do they come in with a 5 year lease and provide all their own equipment, furniture etc. just like an apt?

Just looking for some general insight here.  Seems like a great idea to have a mixed use building to help pay the mortgage... 

thanks
