The landowner allows the land for lease for 99 years which commences from the date the allotment was conducted. After 100 years you (your grand children) will get a notice stating the lease is over.You would then have two options. What is the difference between a regular registration and a 99 year lease registration? If the buyer wants to sell the house how does it work? You flat will be leasehold only as you (or other flat owners) don't own the actual land. By default (unless otherwise mentioned) it is 99 years. Anyone who purchases a residential or commercial property will own it only for a period of 99 years, after which the ownership is given back to the landowner. You can stop into any participating housing agency and pick up an application. It can be filled out and returned onsite or you can drop it off at a later date.
