The primary mortgage institutions should redirect major parts of their loan able funds to building and renovation of residential buildings instead of concentrating on commercial buildings and neglecting residential properties. Such redirection is expected to increase their impact on provision of housing and enhance their contributions to real estate development in Nigerian economy.
