Yes, the house rental trick was big in the European middle ages: sometimes the lender would just pretend to "buy" the borrowers' house, and charge him "rent" for his own house until he "buys" it back.

  Still, the remarkable thing from the Medieval documents we have from the Middle East is that most people actually did follow the rules: they used to do profit-sharing instead of interest; lenders would become partners instead.

  As for the pruzbul I believe that was introduced by Rabbi Hillel around the time of King Herod, a much later period. The remarkable thing is that jubilees were institutionalized in one form or another in much of the Middle East for many thousand years before that and it didn't cause significant economic disruption.
