The county council hereby finds that there is a portion of the county's rental housing being converted to condominium or other status; that such conversions are having the effect of displacing particular segments of the population from the rental housing market, the most vulnerable of whom are elderly and/or handicapped persons of fixed income, and other persons of moderate income; that many such individuals are financially unable to remain in the rental housing market in Montgomery County successfully or to exercise any right of first refusal without special financial assistance; and that loans and grants for rental or purchase assistance for elderly or handicapped persons and rental assistance for other qualified persons are hereby declared to be for a public purpose serving the good government, peace, health and welfare of the county. (1980 L.M.C., ch. 55, § 1; 1982 L.M.C., ch. 1, § 1.)
