I own a small bungalow which has a 100-year lease, of which 65 years remain. It is connected to another bungalow and a small block of flats. If I paid to extend the lease and none of the other properties did, what would be the outcome when their leases ran out?
If the other leases aren’t renewed then in theory ownership of the properties will revert to the freeholder, who would then be able to sell them on. But this is unlikely to happen, since the owners of the properties will presumably want to either live in them or pass them on to their children or relatives in due course.
