We must also ban PRs from buying resale HDB flats. They should only be allowed to rent or buy a condo. HDB flats should also not be allowed to be rented out. PRs are pushing HDB flats prices higher. The HDB market should be closed only to Singapore citizens. PRs and other foreigners should only be allowed to play the condo market. It is ok if condo prices go up further, doubling from today's prices, as this is the private market. As long as the HDB market is affordable to local Singaporeans, then this is ok.
