Can I get a zero-interest mortgage to buy a house?

You can't. According to the inquiry of Zhijun Real Estate Migration Network, when buyers apply for a loan to buy a house, they will calculate the interest according to the mortgage interest rate, loan term and repayment method. In fact, a large part of the loan for buying a house pays interest. If a provident fund user suggests a provident fund loan to buy a house, the interest will be much less. For users with limited maximum amount of provident fund loans, you can try to combine loans.
