This is the main reason. Children will move out of their parents' home as soon as they live independently, and then buy a suite for themselves and their spouses. In any case, they can't live in their parents' home all their lives, and they have little savings just after independence. Choosing a loan to buy a house is a feasible thing to consider.
Moreover, young people need to be honed, because they have used their parents' money since childhood, and they have to rely on their own ability to make money and repay their mortgages. Moreover, it is not a bad thing to buy a house with a loan. People can't live without a fixed place. Loans can help you buy your own house in advance, and mortgages will give you some pressure to make more money, which is a help to temper young people. It is not easy for newly married people to earn money to support their families, and it can also help them develop a frugal habit.
Moreover, for the loan to buy a house, the interest on the loan is generally acceptable, and this kind of loan is safe, unlike usury or campus loans that specifically cheat college students. After all, it is very common to buy a house with a loan, so it is generally credible.
The biggest feature of buying a house with a loan is that even if you don't have enough funds to buy a house at present, it can help you move into a new house in advance and avoid the dilemma of living with your parents after marriage. For young people, it can better temper them, and for a newly married person, it can make them mature quickly.
