Bar converted to Restaurant

[Bernard Chouinard]

I'm looking at buying a 3 unit that has a bar.  The bar is run down hole int he wall that brings in about $40K in GROSS revenues.  I'm thinking I"d rather see it a restaurant as it's equipted for it.  

Could I leave it as is and allow a tenant come in and remodel as they see fit? Or as the owner of the building do I have to do that then rent it out?
