I was thinking along the lines of leasing a small apartment and trying to fill it with furniture from a four bedroom house. Instead of renting storage facilities for the excess furniture, I would tear down the wall into the neighbor's apartment and put some furniture in there.
If they don't like it, they can move. :o)
That's right! Your neightbors shouldn't object to you taking up their space. They can move, or just shut up! :-)
