If renting is illegal, moving without a buyer should be illegal. Wanna go land that cool new job in SV? Before you give them a start date you better find a buyer for your flat. Otherwise you're stuck. It's illegal to make someone else foot the bill when you decide to go somewhere else.
I believe the model is just like renting but the rent is a percentage of the value of the home. When you leave the landlord has to return part of the "rent".
