Question:
Isn't it foolish for real estate agencies to give so much information to the potential flat buyers since more information to buyer tend to increase their bargaining power?

Answer:

	Actually, information is scarce and the collection of it is costly. With the information about flats grouping together on the official website of the real estate agencies, customers' information cost on the price, the availability, the quality etc. of the flats can be reduced.
	Potential buyers are willing to pay a higher price for the service because their information cost is largely saved. This is especially true for those buyers whose time cost is great.
	Also, sales of the agencies may also increase.
