Taking $900 a month from your friend just so the friend could have a roof over their head sounds harmless? And your defense of that action is "at least he's not taking $1400-$1500"?

How about you Venmo me $900 every month and in return if someone comes asking to Venmo them $1500 you can tell them you already got a better deal? Does that sound fair or do I need to own property to make it seem fair?
