>What happens 20 - 30 years from now when this non profit has shuttered and the land is now owned by some random bank?

In my country some cities offered 49 years or 99 years of lease on land to people willing to build homes. Since the land is owned by the city there's no much concern it will got in hands of banks.

That sounds amazing. In my current country and that of my birth you have to fight tooth and nail to be allowed to build anything, at least at the scale an individual can manage to build.
