There are no specific figures available for 99-year leasehold landed properties because they are extremely rare. Most landed homes in Singapore are either freehold or have a 999-year lease, which is often considered akin to freehold due to its long duration. If you are looking for detailed statistics on landed properties, you would typically find data on freehold and 999-year leasehold homes, but not 99-year leasehold landed properties.
