Special Assessment

Special assessment is a charge that a local government imposes on properties within a defined area to pay for a specific public improvement that directly benefits those properties. Unlike general property taxes, which fund broad municipal services, special assessments are tied to particular projects — street paving, sewer or water line installation, sidewalk construction, or streetlight upgrades. The cost of the improvement is divided among the benefiting properties, often based on frontage, lot size, or assessed value, and may be payable as a lump sum or in annual installments over several years.

For mortgage note investors, unpaid special assessments function much like tax liens — they attach to the property and, in most jurisdictions, carry the same super-priority status as property tax obligations. This means an unpaid special assessment can survive foreclosure and must be satisfied before clear title can be transferred. During due diligence, note investors should check for both delinquent and future special assessments, as an upcoming multi-year assessment can reduce the property's effective equity by adding a significant obligation that the next owner will inherit. Special assessments are typically identified through a title search or by contacting the local taxing authority directly.
