The CASS forecasts that the growth of housing prices this year has slowed down from 2009 by as much as 15 percent. But CASS says that's still too high, beyond the affordability of 85 percent of home buyers'. It recommends the government not ease cooling measures on the real estate market, for fear that prices would rebound.

CASS suggests the government boost land supply, and regulate the market through tightening credit and taxation. The official organization also calls for a thorough reform of the current property system.
