Our lease has a clause in it addressing drugs, however we never signed our lease with these tenants, we just left them as month to month.

Can I just tell the bank, “we’re going to move into this apartment as soon as the lease expires and then we will give you proof of address.”?

I just don't understand.If you PM or send me the address I can likely assist further. 

Any comments made by your family could effect you. 

Decide on your cable/internet company, (have your agent ask if the seller can transfer the current service if it's one you like), if they won't transfer, call your favorite provider and ask if they service that address and set it up3.

Nothing is truly passive, but I'd rather work upfront to put a system in place and address the glitches as they pop up than be constantly hopping from deal to deal.

They do state the address?

You made a good point by addressing the question of how we paid it off speaking to the type of investor we are. 

The domino effect will eat your equity as well as life savings.Unload the properties while you think it is the peak price. 

First, check your rental/lease agreement to see if it addresses such an issue that you are facing now.
