1. The online sign of second-hand houses means that when consumers sign a contract with the seller, they must put it on record in the relevant department of real estate, and at the same time, all the information must be published online. This can not only protect the rights and interests of consumers, but also demonstrate the authority of the real estate company, so it is a matter of having the best of both worlds.
2. When the owners successfully record their purchase of second-hand houses, the developers will issue corresponding online tag numbers, and consumers can query every information signed in the process of second-hand house transactions online through the online tag numbers of the Car Association. For example: signing sales contracts, real estate intermediary service contracts, choosing transaction funds custody, etc. In fact, that is to say, second-hand housing online sign can make the real estate transaction more transparent in some ways.
