(Current) Tenants say the dumbest things, too...
So, your tenant made it through the screening process and moved in.
What kind of dumb things are they saying now?
Petty requests?
Requests to remodel?
Requests for upgraded appliances?
Whining about the internet you provide free as a courtesy? (don't do it.. it's not worth it)
Excuses for not paying rent on time?
