I know that in many cases tenants start looking when they get the increase and then realize that it is best to stay.

Every cost adds to my basis in the property and the profit or loss is realized only when the property is sold. 

Most the time tenants will quickly retract their threat once they realize their escalation was met with another escalation. 

Many investors only look at projected returns and invest based on that, and therefore don't realize that the property is barely generating cash flow, because they are getting a 7% return day one.
