Since my first observation of irony was lost on the non-attorney real estate agents in the room who seemed to be too busy practicing law...

This observation suggests that more expensive properties with higher income might be more advantageous.

An observation: Steve Nicewarner is a broker.

And, my observation was that properties linger in their databases long after its been disposed one way or another.The complaint is misleading advertising.

I did not verify this but this was just his observation.

Rather, you have to use it to determine how much you can pay.The 50% rule is an emperical rule from observations of many properties.

I've observed that the overall price is generally lower on personal policies but because they are on separate policies the paperwork is greater.

Was just an observation

There is definitely a need and a niche for congregate housing / boarding houses,  but the management can be a lot of work.While I don't do rent by room I do have some tangential experience / observations : There are several well established such properties in the neighborhood of one of my buildings,  I have had several roommate situations (one lease agreement though)  and my current personal residence was previously a boarding house hosting at least,  but probably more than 4 separate tenants.   

@Eric Hrlbock good observations.
