On a national basis, home sales volume continued to dip in the first five months, but the rate of decline slowed by 4.6 percentage points from the first four months.

As a result, home sales value nationwide rose 3.1 percent in the January-May period from a 3.1-percent decline in the January-April period, the first increase since February 2014.

The bullish stock market created several millionaires over the last few months, which partly contributed to recovering home sales, according to Yahao.

But analysts said pro-growth measures, which have slowly been taking effect, are more significant.

The central bank has cut the benchmark interest rate three times since November. It has also lowered banks' reserve requirement ratio twice since February.

In March, China reduced down payment levels for second-home buyers to 40 percent from the previous 60 to 70 percent, and exempted business tax for sales of homes purchased over two years ago.

Li Qiaoling, an analyst with property agent Home Link, said home transactions are rebounding on the back of such measures.

Home prices are rising in big cities, but still sluggish in small ones.

First-tier cities saw average home prices up 1 percent on a monthly basis in April, whereas those in second- and third-tier cities declined 0.1 percent and 0.3 percent, respectively.

Despite the marginal improvement in major cities, Qin Hong, head of a research center under the Ministry of Housing and Urban-Rural Development, ruled out a sharp hike in home prices nationwide.

"Generally speaking, there is still an oversupply of housing. Therefore, it is unlikely to see skyrocketing prices across the country," said Qin.

Even in first-tier cities where demand exceeds supply, purchase restrictions will help keep prices from rising too rapidly, according to her.

The NBS is scheduled to release home prices in May on Thursday.
