2025 Statistical Revaluation
2025 Property Value Update for Durham Residents
The Town of Durham is working with Whitney Consulting Group, LLC and Town Assessor Darcy Freer to update property values for the 2025 tax year. This update, called a statistical revaluation, is required by the State of New Hampshire to ensure that all property assessments are fair and reflect current real estate market conditions as of April 1, 2025.
The last full revaluation in Durham was completed in 2023, when property assessments were found to be, on average, 94.2% of actual market value. Each year, the Town monitors real estate sales to track changes in property values. For the 2024 tax year, this monitoring showed that assessments had dropped to 82.5% of current market value. In simple terms, this means Durham’s real estate market increased by about 11.7% in just one year. State law requires towns to keep assessments within 90% to 110% of market value after a revaluation. Because our assessments have fallen below this range, this year’s update is necessary to bring property values back in line with the market and make sure everyone is paying their fair share.
What to Expect…
- Preliminary new property values will be mailed to all property owners in late August or September 2025.
- These values are based on recent sales and should reflect what your property could sell for in today’s market.
- You’ll have the opportunity to review your new value and, if you have questions or concerns, schedule a one-on-one informal hearing with the Assessor and Whitney Consulting Group. Instructions for scheduling an appointment will be included with your notice.
It’s important to remember that an increase in your property’s assessed value does not automatically mean your property taxes will go up. After the revaluation, the overall tax rate is adjusted based on the new total town value. Often, when property values go up across the board, the tax rate goes down. Please do not use the current tax rate to estimate your new taxes. The final rate will be set by the state later in the year after all budgets are finalized.
If, after receiving your fall tax bill, you still believe your new assessment does not reflect market value, you have the right to file a formal appeal (called an “abatement request”) with the Town. The deadline for this is March 1, 2026.
We’ll keep you updated throughout this process. Updates will be shared in the weekly Friday Updates e-newsletter (you can sign up at www.ci.durham.nh.us), and more information will be posted on the Assessing Department’s page at www.di.durham.nh.us/assessing starting the week of May 12, 2025.
If you have any questions at any time, please contact the Assessor’s Office at (603) 868-8064. Thank you for your cooperation as we work to keep Durham’s property assessments fair and up to date.
