In the 21st century building houses are expensive. Consequently, the availability and cost of house financing are critical determinants of how well housing market functions are performed all around the world. Institutions involved in lending, including mortgage lending, carefully assess credit risk, which is the possibility that borrowers will fail to pay their loan obligations as scheduled. In Bangladesh the real estate sector is a major employment driver following the agriculture and garments sectors. A large number of industries such as cement, steel, brick, timber, marble, cable, light, building materials etc. are dependent on the real estate industry. Industrial Development Leasing Company Limited (IDLC) is the first and the largest leasing company of Bangladesh. IDLC of Bangladesh limited is established in 1985 as a joint venture public limited company with the multinational collaboration of International Development Finance Institution, Commercial Banks, Insurance Company and Foreign Leasing Corporation.
