You can use the extra funds for investment. Take Qian Shengqian as an example: from the perspective of investment, buyers with loans can use the extra funds for investment and financial management, or use loans to buy a house for rent, so the use of funds is much more flexible.

The bank will also check the quality of real estate projects for you: it is not a small amount to apply for a mortgage loan from the bank, and the loan period is also very long.

If the bank checks for you, the insurance will naturally be much higher. You must know that many people are refused loans by banks every year because their properties fail to pass the customs.
