No harm no foul.

I'm not implying that your broker would purposely do anything to harm you, however, human nature is something you should not ignore.  

For those inclined to suggest, "just register, what's the harm?"

You have to have running water, working plumbing, doors that lock, a heat source, a stove, no adverse conditions that would be harmful to health (mold, vermin, etc.) 

I would say that human nature tells us that although this is certainly possible, it is putting someone in a position of power which in turn puts them in a position of temptation and potentially harming a lot of others in the community.On another note, this sounds quite similar to many Communal Living situations that I think try to achieve sort of what your describing (minus the ability to relocate easily).

And when they freak out, they often make decisions that will harm them more in the long run.

No harm in setting lofty goals!

Major changes and upwards movement at workplace.

No harm in asking the previous owner if they will help out.
