I'm not usually surprised by people's poor behavior but this one hurt a bit.

You could also remove any locks between the basement and main house or the downstairs bedroom if they exist to discourage this behavior.  

Do not reward this defIant behavior and offer cash for keys , that is a hail Mary last resort . iN the sprirIt of tryIng to save money In an evIctIon , I’d make one last phone call to the tenant and explain that you are going to march down to the magistrates office and throw them out unless the animal is gone by the following day .

I am now trying to pay my credit card, and they are asking me to enter my CC# and 3 digit security code in order to display my CC bill and pay it.

If I were to base my RE investment choices solely on hood properties, I am essentially transferring a portion of my success probability on to the behavior of people in the hood.
