I always wonder what happens to your skyscraper 50 or 100 years from now.

If I buy a house I own assets for the price of the house plus the price of the land on which it sits. If the house burns down I still own the land underneath.

But if I buy an apartment on a skyscraper and it is deemed uninhabitable all I end up with is the price of the land minus the price of demolishing a skyscrapper divided by the number of people living there. That doesn't sound like a good investment long-term.
