Sort of. So far as I can tell, you can withdraw to buy housing but I don’t think you can pay rent out of it.
The loans are also 75% max loan-to-value so I think until you can get 25% of the purchase price in your account you have to pay CPF and rent (or live with family).
Also, not an economist, but I suspect the forced savings has a wildly inflationary effect on housing prices. You can’t do much else with the money until you retire, so I would guess the price of housing rises up to match the forced savings rate.

Housing prices are inflationary independent of CPF, because flats in Singapore are powerful investment vehicles. For HDB flats, however, there is means-testing and rebates to the amount of ~50%, sufficient for anyone on the 30th percentile and above to afford.
Very few locals pay rent here. Most people buy houses. Its kindof forced thanks to the system, but its designed in a way that unless you are a decimillionaire housing is expensive, but attainable. This is done by splitting the housing market into private and public housing. Is this perfect? No.
And yes it does drive inflation of house prices.
