In the event that there are more applicants for affordable housing in any development than there are vacancies for such housing, the units shall initially be made available to low- and moderate-income households currently living or working in the region consisting of Bergen County, Hudson County, Passaic County and Sussex County. For initial occupancy priority, households shall be screened according to the above preference. Those households qualifying for priority shall be offered contracts of sale and/or lease first and before other income eligible households. When housing units have been purchased or leased by all households qualifying according to the priority standards, the remaining income eligible applicants, not yet under contract, shall be pooled and offered contracts. Within all rounds of applicant selection, random selection of eligible applicants shall prevail.
