Is it true that ABC paid off the mortgage in advance?

It is true that the Agricultural Bank of China repaid the mortgage in advance. In the past, why people didn't want to repay the mortgage in advance was because the value of the house had turned over many times. The average house price in China was 2,000 yuan per square meter at 1998, but now it has exceeded 1000 yuan per square meter. For 20 years, the house price has been rising, and the interest paid for so many years can be ignored. With the current real estate situation, can you guarantee that the house price will change from the current 1 0,000 to an average price of 50,000 in 20 years? I think it's probably impossible.
