I asked this question in the Wisdom of the Crowd:

What is the best way to preserve the value of HDB flats

Here are the responses: (49 Votes)

65 % - Allow lease to be extended at nominal cost.
18 % - Give a grant to owners to buy a new flat on expiry of the lease.
16 % - Allow owners to opt for VERS (voluntary enbloc redevelopment scheme)
0 % - Introduce upgrading (HIP2).
