Maybe your UK argument would work in a US court, and maybe not. 

Your business is not worth taking unnecessary gambles unless they are the last tenant on earth.

Aside from that, I'd prefer a known good tenant over a gamble any day.  

If it's a wash, or an unknown gamble, then you are wasting your time to do any more to the property.It's a tough decision only you can answer but right now it's costing you more money to hold. 

It's a gamble, though.Just be sure what you do is legal.  

Then, he'd tell me that so and so had been gambling, and so and so is into porn, and so and so got a rabbit, but we can't kick her out because then we'd have to tell her we found out by going through her garbage.  

Or, the Landlord can take possession and charge them rent until he finds a new tenant.Requiring giving the tenant the choice of a termination fee or gambling on the other landlord options, is actually a tenant-friendly move for FL.  

Gambling?  

Unless you're willing to gamble on anything you might find later, I'd run away.And I don't think it's odd to want a place inspected, even if you haven't seen it.  

Or if you are willing to gamble that investment money in the hands of strangers.I wouldn't be.You may think I'm just a negative person.
