That is a standard answer provided by many other firms China Daily interviewed. Small agencies in Beijing offer big discounts, but most home seekers still choose major agencies like HomeLink, which takes up almost half the pre-owned home sale market. The privately held company did not disclose its earnings, but ubiquitous stores, bloated broker teams and unsubdued commission fees suggest it is not on the verge of collapse.

Quite the opposite, based on its strong offline presence and abundant home sources, the company was able to fight a war with SouFun Holdings Ltd, owner of China's largest real estate Internet portal.

In October 2014, HomeLink decided to stop its cooperation with Sou-Fun and scrapped all its listings on the website, citing rising fees charged by the latter. The decision, along with other brokerages' boycott, dealt a heavy blow to the website, which relied heavily on the listing fees paid by brokerages. The NYSE-listed company's share prices tumbled to $7.26 as of Tuesday, from a peak of $19.4. HomeLink switched to upgrade its own housing information website.

SouFun responded to the crisis by announcing its intention to expand from a pure-media platform to a "three-in-one" information, transaction and financial platform. But whether that would bring in new sources of revenue still remains unclear.

"Despite being a significant revenue opportunity, we view the visibility of such a transition as very low at the current stage. Moreover, unlike Ctrip.com International Ltd's investment and transition, SouFun's new initiatives could potentially create conflict between itself and current business partners and lead to a negative impact in the near future. We suggest investors stay on the side-lines until further visibility arises," wrote JPMorgan Chase & Co's analysts in a November note.

In the eyes of a new wave of crusaders in the industry, both brick-and-mortar brokerages represented by HomeLink, and e-commerce sites represented by SouFun are "old forces" whose traditional business model equates to redundant, if not totally useless, presences.

They see traditional brokerages opening too many stores, hiring too many staff, and charging too much fees. If the whole business model could be reinvented to skip stores and cut staff, commission fees could be brought down while business remains profitable.

That is what iwjw.com, a new venture created by some Internet veterans last March, is doing. Focused on the home lease business, the company cut the previous commission (a month's rent) to half, and poached brokers from brokerages by promising to at least double their base salary.

The strategy worked. In Shanghai, the company promised zero fee for rent seekers, and iwjw quickly rose from irrelevance to being the favorite of customers.

Deng Wei, founder of the company, said iwjw took the offensive by punching the "aching points" of the traditional industry, including unnecessary stores, poor service, fake home information on their websites and high charges. She said most brokers stayed idle all day long, which is a huge waste. And brokers take an indifferent attitude toward those wanting to rent houses, because selling a property is much more lucrative than a leasing deal.

Analysts agree with the criticism, but said despite its flaws, the role of traditional middlemen remain irreplaceable. Unlike trivial spending online, house purchases involve huge amounts and are the most expensive lifetime spending for most Chinese people.

Agents play a critical role from house tours, price negotiations and contract signing－no matter how much buyers and sellers resent them.

"In most cases prices would not be settled without agents. In a human capital-intensive industry, people, and the talent and expertise associated with them, play a key role," said Frank Chen, executive director and head of CBRE Research China.

"The value of Internet companies are that they shake up the status quo. But even after the disruption effect was made, most of the challengers ended up not making money－much like e-commerce in China."

Iwjw also faced some problems recently like inaccurate information, laggard service, money splurge etc.

SouFun is struggling to jump start its new businesses, while HomeLink is trying hard to preserve its broker pool, which is getting eroded by rivals. There seems to be no end in sight for the tangled warfare, and it is quite likely that none will end up as the winner.
