Singapore's public housing flat resale prices rose by a record 2 percent in the third quarter compared with last quarter, the city-state's Housing and Development Board (HDB) released its flash estimate on Monday.

It was the fastest rise this year ever since Q3 in 2011. According to earlier official data, the resale prices rose by 1.3 percent in this Q2, following the 0.6 percent climb in Q1.

The HDB has recently further ramped up public housing flat supply by announcing on last Thursday that its government-built new flat supply for this year will be increased by 2,000 units to 27,000, in order to meet housing demand, especially from first- time home buyers.

The agency encouraged the young couples to set up their first homes by applying for new flats built by the government, from which they can also get various housing grants.

The government has increased the supply of new flats over the past two years to curb rising resale flat prices. It launched about 25,000 new flats in 2011.

On the private home prices part, people can also see a rise of 0.5 percent during the third quarter, following the quarterly rise of 0.4 percent in the second quarter and the 0.1 percent drop in the first quarter.
