If HDB really respected market forces, then the grant for resale HDB should be equal or LOWER than new BTO bought HDB (unless HDB admits to giving an implicit (secret) discount for BTO units)- then the subsidy for resale HDB should be equal to BTO HDB or in fact lower (with the remainder placed into CPF very special account for future new HDB purchase wrt shortened lease of resale HDB be insufficient for owners lifetime due to short ending lease HDB flat purchased).
Otherwise, the subsidy is an implicit funding to artificially increase the prices of resale HDB, which is like fueling a ponzi scheme to deceptively keep HDB resale prices high with tax payers money.
If HDB underestimated the demand by PR and the death rate of HDB owners resulting in diminished supply and excessive demand for resale market HDB flats, then perhaps PR should be temporarily banned from buying HDB flats or be allowed to buy direct from HDB but at a much higher price. Gahmen can also release more land for developers to bid for to lower private property prices so more Singaporeans will upgrade and thus increase supply of resale HDB and so lower prices so taxpayers moneys will not be misused to prop up HDB prices.
"There are quite a few government grants and subsidies in Singapore – probably more than you know of! – even if you’re getting a resale HDB flat and not a BTO.
We’ve done the math: You can get up to $160,000 in grants when buying a HDB resale flat. That’s probably a quarter of the price of your new home covered.
P.S. The maximum grant amount you can get for BTO flat is $80,000. So even if your resale alternative is pricier, you’ve got more grants to help!"
