What happens if the land a mortgaged condo is on is sold, and the landowner wants to build a mall, hotel, etc?

For example, you bought a condo with a 30 yr mortgage, and 10 years later the property owner sells the property to a big developer for billions. The developer now wants to level the condos and build a giant mall complex, what happens? Do you still have to pay the remaining 20yrs? Do they *have to* buy your condo at full mortgage value? What if they bought it at market rate, and it's lower then what you signed for?

What actually happens in this scenario?

Keep in mind know nothing of real estate, so I may facts wrong.

You would know about this months if not years in advance as the land would have to be rezoned and there would be several public hearings.

If the land DID get rezoned, the developer would have to buy out the current residents at fair market prices or at whatever deal the current residents would make with the landowner or developer.

It would be pretty rare that this would ever happen though as urban planners have (or should have) long term plans for land use.

When you buy a condo, you purchase the unit & then you have a X% interest in the common areas. It is highly unlikely the land is separate & could be sold & the condo's demo'd. No lender would loan money to anyone buying a condo if this could happen.

The owner can't sell the property, you own your condo and everyone owns an interest in the common areas. This scenario is not possible.
