Uh, huh? I have tons of tenants on m2m. We don't charge or collect (or pay) a tax. These are normal term tenants like if they were in a 12 month. Just because they're m2m doesn't mean it's comparable to an airbnb setup.
Month to month leases are not short term leases, usually they are 1 year leases that are transitioned into moth to month when the lease term expires thus making this completely different from Air BnB style rentals
