We are very careful to prohibit behaviors not people.We can prohibit the act of smoking on the property, or at least inside.We don't prohibit people who identify as smokers from renting with us - we just tell them they can't smoke on the premises (however we define that) and then outline what the consequences of violating that policy will be. 

Do you think that behavior was typical of all tenants in that situation or more so those individuals?

EXPECT what you ACCEPTyou have accepted this poor behavior, and there is no chance it will change going forward.

Funny because what you claim to be theory is me describing normal market maturation behavior.

The biggest problems that investors/speculators deal with are:Defining riskManaging riskDeveloped processes and proceduresExecuting the planTo many new investors/speculators focus on activities that have nothing to do with investing, market behavior...

If they see shady behavior (i.e. the space they lease being offered for lease without them telling you they are leaving), you will likely lose good tenants and good will.

Think about it, this is when they are on their best behavior and want something from you, namely acceptance.

It was mostly, however, information pertaining to the average income, who the citizens of the town were, their behavior.. etc.  

I've done many deals without using my money, my credit was never an issue in most of my dealings.What can be critical is the perception of others thinking you have good credit, that really is based on your ethical behavior, how you present yourself professionally......again, education is the foundation here.

Yes, sometimes you can jail them for this behavior, but it's a essentially lose-lose situation.I definitely wouldn't give them half the bill, but something small so that you aren't completely antagonistic with them.
