Does a Property Tax Assessment Change After a Home Sale in Nassau County?

Many buyers assume that purchasing a home automatically causes the property's assessment to increase. In Nassau County, a sale by itself does not necessarily change the property's assessment.

Property assessments are determined through the county assessment system rather than the home's most recent selling price alone. While a sale may become one piece of market information, the assessment process considers many factors.

New homeowners should review their official assessment record, property description and available exemptions after closing to make sure the information is accurate.

If the assessment appears inconsistent with similar properties, homeowners may wish to review comparable properties before considering an assessment review.
