Low-rent housing
It is neither realistic nor reasonable to expect that commercial housing can be the sole way to guarantee that all residents have their own homes. The ever soaring housing prices make it a pie in the sky for those low-income residents and those who rely on basic-living allowances from the government to buy houses on their own.
For this reason, the central government in 1999 introduced a policy requiring governments at various levels to use a certain percentage of income from land transfers for commercial housing to build low-rent housing for low-income families.
This is a realistic way to solve the housing problem for low-income residents and it is also the responsibility of governments at various levels to provide cheap housing for the poor.
