For real estate, it is possible. Generally speaking, there are many materials that can increase the bank's credit limit, such as the following: 1. Proof of financial resources: a copy of the real estate certificate (more than 50 square meters or worth more than 300,000 ), copy of car driving license (private car, worth more than 50,000, used for no more than 5 years);

2. Qualification certificate: certified accountant, lawyer, economist, tax accountant, appraiser, etc. A copy of the qualification certificate can directly apply for a gold card;

3. Bank current account: a copy of the bank account deposit slip;

4. Private business owner: a business with a registered capital of not less than 1 million Copy of license copy.

In addition, you can also use some tricks when swiping your credit card to help increase the limit and increase your credit rating, such as:

1. Repay on time and never default. It will definitely be impossible to raise the limit, and it will also affect future loans.

2. The amount should be as large as possible. The closer to the maximum amount that can be used, the better. Generally, it should exceed 30% of the amount.

3. Make as many purchases as possible with a higher frequency, with an average of more than 10 purchases per month. If there are more than 20 purchases, it will be easier to increase the limit.

4. Try to spend more money at physical merchants, less online shopping, and less bulk purchase of bulk commodities.
