Declaration of policy.

(b) It is further found and declared that unless the supply of housing and the ability of low and moderate income families and persons to obtain mortgage financing is increased significantly and expeditiously, a large number of residents of many of the state's municipalities will be compelled to live in unsanitary, overcrowded and unsafe conditions to the detriment of the health, welfare and well-being of these persons and of the whole community of which they are a part. By increasing the housing supply of the state and the ability of low and moderate income families and persons to obtain mortgage financing, the clearance, replanning, development and redevelopment of blighted areas will be aided, and the critical shortage of adequate housing will be ameliorated. (c) It is further found and declared that the cost of mortgage financing is a major factor materially affecting the supply and cost of housing and that, notwithstanding the past and present efforts of government agencies and instrumentalities both state and federal, there continues to exist a serious shortage of low interest mortgage financing available to low and moderate income families and persons in the state. It is therefore necessary and appropriate that municipalities take steps on a local level to reduce the cost of such financing and thereby promote the purchase of decent, safe and sanitary housing and the rehabilitation of existing substandard housing by low and moderate income families and persons. (d) It is further found and declared that the provision by municipalities of financial assistance for housing for low and moderate income families and persons through the making and purchase of mortgage loans to such families and persons for the purpose of purchasing and of rehabilitating housing, are public purposes and purposes for which public money may be expended by a municipality for the public benefit and good.
