The source of the data must be the most accurate data of the Housing Authority, because it is necessary to sign online. Still, the bank's data is accurate, because banks are definitely not allowed to open loans. There are so many banks, and each one will not be too complete.
So if you want to check this kind of data, go to the website of the local housing authority first. However, it is generally hidden deeper. After all, it is not a professional internet company, and the website is well displayed.
Secondly, to some third-party organizations, because the Housing Authority also wants third-party organizations to participate in the analysis and collation of data, most of them will share transaction data with third parties.
Recommend the data of Kerry, Middle Finger and Seven Fish.
The first two kinds of costs are higher, mainly facing the public data of housing enterprises, belonging to procurement data; For individuals or small and medium-sized real estate-related institutions, the procurement cost will be very large.
And relatively speaking, Kerry and the middle finger are more statistical data, and it is impossible to be very detailed.
If individuals invest in real estate or do data research, then it is best to have the underlying data, that is, it is subdivided into daily life, each community, each room, area, apartment type and transaction price.
Generally speaking, the data of second-hand housing, except the number and area of online signing (transfer), other published transaction prices are for reference only, which is quite different from the actual transaction data.
In the simplest way, in order to reduce taxes and fees when transferring second-hand houses, the contract price is generally lower (but it must be above the "evaluation price"), which can effectively reduce the taxes and fees of buyers and sellers.
Therefore, the price index of second-hand houses published in various places is not very accurate.
If you want a new house, you have to access the system of the Housing Authority for online signing. The Housing Authority itself does not sell data. Generally, third-party data companies cooperate with the Housing Authority to open the system, sort out and handle all the filing (release pre-sale information, etc. ) and online signing data, and then open the corresponding ports (websites and accounts) and sell them to developers or corresponding research institutions.
This kind of information is charged, and ordinary people can't spend so much money to buy it.
The statistical dimensions of the middle finger database and Ke Rui are different, and the data obtained from the same variable are also different, but the real estate transaction data of monitored cities are published regularly. Can be obtained in official website or other channels, Baidu can also search.
If you want to customize the data query, you can only buy the corresponding service.
Housing management bureaus in individual areas will also provide corresponding data queries on "third-party" real estate portals. I only see that the data of two cities are public, and the data of other cities need to be purchased separately.
If you are only interested, you can search for relevant city keywords and inquire about the weekly, monthly, quarterly, semi-annual and annual reports of the real estate market published by professional institutions.
