The cost of owning a home is becoming an increasingly heavy burden on middle-income families, a report from the Chinese Academy of Social Sciences has shown.
And with the central bank's recent interest rate rise, the situation is set to get worse, Wang Lina, a researcher with the academy and author of the report, said.
Since 2004, housing payments have been eating more and more into families' incomes, with most households now spending about half their total income on loan repayments, Wang said.
"This is a worrying situation. If the interest rate increases further, those who cannot afford to buy a house now will never be able to buy one," she said.
Wang's conclusion was drawn after she and colleagues conducted a two-month-long study in Shanghai, Beijing and Shenzhen, where house prices have been soaring.
Statistics from the National Development and Reform Commission showed that house prices in 70 major cities in the country rose by 5.3 percent last month.
Shenzhen and Beijing led the pack with nearly double-digit increases.
Despite a series of measures being adopted to regulate and stabilize the property market in recent years, prices have continued to rise across the country, especially in the major cities.
The report said that the steady increases were due to the country's rapid economic development, which had created a huge gap between supply and demand.
In major cities like Beijing and Shanghai, which have huge floating populations, the demand for property is even greater.
More than one-third of the houses in Beijing are owned by non-Beijing residents, the report said. In Shanghai the figure is about a quarter.
The report also found that about 43 percent of Beijing's high-end properties, with an average price of more than 10,000 yuan (US$1,294) per square meter, were bought by non-Beijing residents.
The ever-increasing prices are leading to mounting pressure on the so-called "housing slaves" who are forced to lead frugal lives in an effort to make monthly loan payments.
Adding insult to injury, the recent interest rate rise, which was intended to help rein in inflation and the excessive growth in credit, has worst affected low-income families.
Since the rise, middle-income families have found themselves spending an extra 4 percent of their monthly incomes on housing repayments, while the figure for low-income families is 8 percent.
Middle-income families are defined as those earning a between 60,000 and 500,000 yuan (US$7,765-64,716) a year, the academy said.
