so what if someone buy,....after all is not yours, got to return bank to gov after 99 years...
No one have live that long enough to know what will happen.
The first HDB were built during 1966 to 1970...
Add 99 years to those HDB, and + if you live long enough, you will know whether the Government Buy back the HDB or just evict your decendents out of their flats...
For me, I hope the GOV buys back from our decendents our hard earned pigeon hole... or at least give our decendents a replacement pigeon hole, anyways, HDB already make so much money building and selling pigeon holes already, giving a few blocks here and there won't hurt right?
