Any ideas on the best way to find out about the mobile home disturbing tenants as little as possible or how to find out what tenants are currently paying to rent from Bank of America—if anything?

I try to be mindful of the tenants next door because I don't want to disturb them too much.

I would find it rude for a potential buyer disturbing tenants.

I had several issues with them: smoking in the unit with the smell disturbing the neighbors, additional people (3) living in the unit that were not on the lease, not communicating with me when there were water leaks or repairs needed, and they left it filthy when they moved out. 

And if the property happen to be close to where you live, seller do not like to disturb tenant and would not let you see the property. 

You could also add in that you will be allowed access for showings, for example, each Saturday from 1-3PM, beginning July X, whenever you return from your vacation, but if you're doing repairs after they leave, anyway, I'd usually just let them go without disturbing them, especially if they have pets, then put a sign in the yard while I'm working on it.    

@Bryan BeyersIf it is for sure illegal for him to do that, make anonymous calls to the police for noise disturbance.

Could be as small as a dead battery in a smoke detector in the middle of the night (no guest wants to hear beeping while they are trying to sleep), guests can get rowdy and disturb neighbors, I have even had guests that insisted upon having someone meet them face to face when they arrive.

No aging absentee landlord answering to the name of Jimmy having the tranquility of his nap in the Greek islands disturbed to authorize paying the property manager, the plumber, and the county inspector their respective pounds of flesh for the repair.I do it for lousy tenants and for good tenants.

And @Omar Khan you make me think the same thing which is fairly disturbing to me because I've heard your name mentioned as a 'financial expert'  around multi-family properties.Are you saying that it's in anyway ok to be dishonest or mis-leading or immoral just because the banks are?
