可申请过桥贷款 (bridging loan)
A bridging loan is a short-term loan offered by a bank, which will serve the purpose bridging the monetary gap between the sale of your old house and the purchase of your new home.
These loans are designed to tide you over until you receive the proceeds from the sale of your old house. In some cases, it also includes until you find a suitable buyer for your property. These loans are a short-term financing solution that is meant to be fully repaid within 6 to 12 months.
A bridging loan can be used for more than just purchasing a new home. A bridging loan can also be used to renovate your home while waiting for approval on your mortgage application.
