The apartment will have a risk assessment for the tenant review. If the amount of i20 is not enough to cover the amount required by the apartment, we are forced to find a guarantee company to guarantee for us, so that we can pass the apartment review and finally sign a satisfactory house. Generally, this situation will occur when a person wants to book a two-bedroom apartment, but the i20 amount is too low, and the building will estimate that the tenant will not be able to pay the rent on time. uhomes can provide you with a guarantee company and assist you in completing the guarantee process. However, the services of the guarantee company are not gratuitous. They usually need to charge one month's rent equivalent as a guarantee service fee, and only need to pay once. The specific payment amount is subject to the certificate issued by the guarantee company.
