I found a lot of income certificates for you, most of which are fake water. Buying a house with a loan cannot bypass the "proof of income", because the proof of income is an important proof of the income of the loan applicant, and the bank also grants the credit line according to the lender's proof of income. Under normal circumstances, people will need proof of income when buying a house or a car, mainly to let banks know their income, so as to obtain mortgage and car loan. However, in life, in fact, many people's income certificates are false. For example, some people will find a company seal and then forge a proof of income.
