Mortgage housing loan refers to the commodity housing varieties that can be listed and circulated under the borrower's name to mortgage bank loans. Unlike second-hand housing loans and first-hand housing loans, customers already own real estate, not about to own it. Mortgage housing loans need to have clear loan purposes and cannot be used for purposes explicitly prohibited by laws and regulations, such as real estate speculation and stock speculation. It is required that mortgage housing loans should be earmarked for special purposes and be supervised by lenders and regulatory agencies. If violations are found, the bank has the right to recover the loan.
