Formal Grievances

Formal Grievances can be filed at the Assessor's Office between May 1st and 8:00 p.m. on the 4th Tuesday of May. Once a grievance is received in the Assessor’s Office, you can schedule an appointment to appear before the Board of Assessment Review. You are not required to appear and can submit a grievance for review only. More information on the formal grievance procedure is provided below:

Guidance Regarding Comparable Sales & Time Adjustments

The sales books provided below are the valid sales that occurred in town that were used to determine assessments. Sales dated between 11/1/2019-12/31/2022 were used. If you find sales using other sources, please cross reference them to make sure they are valid. INVALID sales include: estate, trust, foreclosure, short, flips or not listed on the Multiple Listing Service.

**Please note the sale books below provide the sale price, rather than the time adjusted sale price. These sales should be time adjusted as that is how the mass valuation modeling handles them when developing market value.

What does a time adjustment mean? It is an estimate of what a sale that occurred before or after the valuation date would sell for on the valuation date (July 1, 2022). This adjustment is determined by analyzing sales that have occurred in the market. The State of NY assigns a trend each year to every town. For the purpose of this reassessment the time adjustments made to sales were calculated as follows: 11/1/2019 through 12/31/2020-adjustment 8%, 1/1/2021 through 12/31/2021-adjustment 8%, 1/1/2022 through 12/31/2022-adjustment 10%.

The perfect sale occurring on July 1, 2022 would have no time adjustment. Sales occurring 11/2019 through 6/2022 would have adjustments between +21% through +1%. Sales occurring between 8/2022 and 12/22 would have adjustments between -1% through -4%.
