Please provide the tenure start date for the 99-year lease of the HDB project at 451A Sengkang West Way.

For HDB flats in Singapore, the 99-year lease commencement date typically starts when the first occupiers take possession of the keys to their flat. This is usually after the construction of the building is completed and the Temporary Occupation Permit (TOP) or Certificate of Statutory Completion (CSC) has been issued.

In the case of 451A Sengkang West Way, since it was completed in 2013, the 99-year lease would have commenced around that time, once the residents took possession of their units. The exact lease commencement date can vary slightly depending on when each resident collected their keys and took possession of their flat.
