I have been through 2 enblocs, so I think I am qualified to share with u. In a private enbloc, no matter it is 99 or 999 years, the project land is strata divided among all the condo owners including the unit owner's unit title. Herein lies the major difference.

Well Said!  HDB lessees have no possession of any strata titles since they have no ownership of the land where their block is situated on.  As such, the HDB is not being fair to their tenants by calculating the land cost when evaluating the price of its flats.
