The consequences of not filing the maintenance fund are very serious, and it is impossible to get the real estate license without filing it. After you sign the house purchase contract, the developer will deposit your house payment into the fund supervision account, and then apply for filing the house purchase contract. The general real estate bureau will successfully file the contract within three working days. At this time, you can check your house information on the official website of the Real Estate Bureau according to the record number and ID number on the filing page. After handing over the house, the developer will change the big card under his name into a small card under the name of the room number. Only these small certificates can the owners pay overhaul fund.
