The application for real estate license of new houses is generally made by developers and takes a long time. Due to the different situation between the city and the developer, the specific time for obtaining the permit mainly depends on the agreed time on the purchase contract. Generally speaking, the period from 90 days to 180 days agreed in the contract is within the normal range, and the longest period shall not exceed two years. If the contract does not stipulate the time limit for handling the real estate license, according to the relevant national laws and regulations: if it is an auction house, the developer must handle the real estate license within 90 days from the date of delivery; If it is an existing house, you need to apply for a real estate license within 90 days from the date of conclusion of the contract. In addition, if you buy a house in full, if you need to apply for a bank mortgage, you can also ask the developer for relevant information and go to the Housing Authority to apply for a real estate license in a relatively short period of time.
