You said that your loan period can last for 20 or 30 years, and it must be a mortgage loan. The interest rate of this kind of loan is very low, basically around LPR. There are only four or five points a year, and even if it rises again, it will be five or six points.
You should consider that the actual inflation rate may exceed 10% every year, so cheap bank loans are actually hard to get. The longer you borrow, the greater the effect of using bank loans to offset inflation. From this perspective, it must be a long-term and cost-effective loan.
Of course, you seem to have paid more interest after borrowing for a long time, but now you have enough money to make other investments or improve your quality of life. You know, money will depreciate sharply in the future, so you should pay as much fixed money as possible in the future, which is equivalent to paying less in the future. This extra interest is nothing compared with the actual depreciation of the currency.
So low-interest loans can last as long as possible, and you will find that the money behind them is useless in the future.
The loan term depends on your income and the efficiency of your capital utilization.
If you are an ordinary working class, you can honestly go to work every month to earn money, and the income is clear at a glance, then according to the income. Don't pay more than half of your income every month. How many years can you keep it, as long as you meet this standard.
Because when I first started buying a house, I was the poorest. All my savings were used for down payment, and I even borrowed money from my parents. In this case, the repayment pressure should not be too great.
In a few years, the money you borrowed has been paid off, and you have a deposit. You can consider repaying the loan in advance. Many banks have some rules about repaying loans in advance. The longest rule is that there is a penalty interest for repaying the loan in advance within two years, and the short one may be half a year. Different banks have different rules. Therefore, repaying the loan several years in advance can avoid this situation.
If you are in business, then you should know that housing loan is the longest loan with the lowest interest rate among all loans. It's a pity that we didn't make full use of it at this time. Some people say that they can engage in commercial loans and mortgage loans, with short term but high interest rates. So if you can borrow for 30 years, don't borrow for 25 years. The longer the time, the cheaper it is.
Others will make some other investments, and the investment income is much higher than the mortgage interest rate. This kind of loan needs to be repaid for a few more years, so you can earn some interest difference.
