Sandy mortgaged her 10 hectare land to ABC Lending Inc. to secure her 10 million loan. After paying off half her loan, Sandy defaulted on her monthly payments due to business losses. ABC Lending foreclosed the mortgage on said property. In the public auction for the 10 hectare land, ABC's bid won and therefore claimed the mortgaged property. The current assessed value of said land is only at 3 million but Sandy's remaining balance from her loan is still 5 million. Hence, ABC Lending Inc. demanded Sandy to pay off the deficiency. Is Sandy liable to pay the deficiency? Explain
