If the secret is that it is the first suite, but the loan tax deduction shows that it is not the first suite, it may be because the loan application failed to pass the examination. The loan application needs to meet certain conditions, for example, the applicant needs to buy a property. If the applicant has not bought a real estate, he cannot enjoy the preferential policy of the first suite. Therefore, if the loan application is not approved, the system may show that it is not the first suite.
