Prospective commercial tenants have bad Credit

[Marshall Rousseau]

Trying to make a decision.  Any advice would be helpful. I bought a mixed use property in a very rule town of 3K people. I bought the property for the residential units, but there are a couple small commercial units as well that the town requires are used for a commercial purpose. I was anticipating not even being able to rent out these units, but I put one up for rent at a low price and after a week found some perspective tenants. Everything checks out except they have terrible credit. If this were a residential unit, I would be immediately turn them down, but it is very likely that this unit would either take many months to get tenants in, or it would not fill at all. All my experience is with residential properties so I don't have a great understanding of the difficulty involved with evicting commercial tenants. They mentioned they could get a cosigner. My gutt is telling me to double the deposit and go with it because the realistic alternative is the unit sitting empty. Some more details below. Thanks!
