The sale of tax liens has long been a method for the collection of delinquent property taxes, water and sewer charges, and other assessments by municipalities in New Jersey. An efficient market for these liens, which are often acquired by sophisticated entities holding extensive tax sale certificate portfolios, ensures that municipalities do not suffer the financial consequences of delinquent property owners. On the other hand, the statutory tax sale scheme, which awards tax sale certificates to the bidder of the lowest rate of interest on unpaid taxes, affords those same property owners an opportunity to redeem the certificates at a reasonable cost before a final tax foreclosure sale.
