2025 Statistical Revaluation

2025 Preliminary Revaluation Values- Residential
The Town of Durham in conjunction with Whitney Consulting Group, LLC has completed an update of all residential property values for the 2025 tax year. These updated assessments are based on real estate market activity over the past several years and are intended to reflect each property’s estimated market value as of April 1, 2025.  For residential property owners, you will receive notice of your new assessment by mail in the coming days. Commercial valuations are still in progress and notices will be mailed shortly.

Do NOT apply the current tax rate to your preliminary assessed value. The new tax rate will be set in the coming month by the NH Department of Revenue. The new tax rate will be adjusted based on the new total value of the Town. Often when property values go up across the board, the tax rate goes down.

This statistical revaluation process helps ensure a fair and equitable distribution of the property tax burden by aligning assessed values with current market conditions. The last town-wide revaluation was conducted in 2023. Since then, the real estate market- particularly residential- has continued to experience significant appreciation. Durham’s preliminary residential property assessments have increased on average by 22% across all strata.  This can further be broken down into the different residential strata, improved residential properties have increased on average by 21%. The waterfront properties within this stratum have seen a more drastic increase ranging on average from 21-65%. The condominium properties have increased on average by 22% and residential land has increased on average by 55%. All commercial property valuations are still in progress.
