I love the way you added wisdom and caution in your analysis of the situation! 

Some people walk very "heavy footed", some people unconsciously tap their foot, pace back and forth, etc....even just dropping the remote control for an xbox can make noise that sound like you are dropping a hammer....the area rugs will help, but, sometimes the downstairs tenant cant handle living underneath, sometimes the upstairs tenant can't manage to not be a naturally(unintentional) noisy neighbor, and other times one of them is just a psycho.Of the hundreds of tenants I have had at that building, I would say most try their best to walk softly and be aware of the neighbors(especially if you have soft way of encouraging that type of empathy), and the ones that are not good at living below people, eventually move.

Thanks in advance for the collective BP wisdom!

Thank you for your words of wisdom!

Thanks for the wisdom, Joe! 

I am going to go against prevailing wisdom in this thread.

I saw something online that each unit has to be sub metered to get a utility bill so each tenant gets charged properly. does anyone have any words of wisdom on this topic?

Words of wisdom?

Thanks all for your wisdom and input!

I did do credit checks however.....In closing it seems like a high risk proposition to provide a stranger with such sensitive and potentially harmful information.I would appreciate the opinions of those who use these forms and your opinion as to the wisdom of providing such detailed information.Thanks in advance.
