Raising this a level... I don't know if you can do this anymore, but a long time ago (like ~25 years ago) a couple I know lived at very low rent in houses that were for sale, but where the owner had already moved out.

They were typically very nice and very expensive houses where the realtor needed the house to be in showable condition at a moment's notice, so in exchange for under 25% market rate rent, they just had to make sure that the house was clean and be ready to leave within an hour if there was going to be a showing. Since the houses were pretty pricy and upscale, they tended to take a very long time to sell so they were usually there for quite a while.

Not quite what OP wants, but almost free housing is nothing to sneeze at.
