First of all, if you have a loan, you can't get a real estate license. It's all mortgaged in the bank.

Then, if you own a second-hand house, you can get a copy of the real estate license and land certificate when you borrow money.

If you buy directly from the developer, it will definitely take several months. I didn't have a real estate license until half a year later, and then I came to the housing management office to make a copy.
