Yeah, you're being way more pedantic than I was a few posts up.

My point was only that in an SRO/boarding house situation, the tenant has no control, and at any given point in time, the tenant in the next room could change.

And in a shared home "joint and several" lease situation, the tenants control who can live in the home at the beginning of the lease (but, yes, they're effectively locked into that arrangement for the duration of the lease).

Yes, in both cases, the landlord generally has more power than the tenants. That wasn't my point.
