Don’t confuse Assessed Value with Market Value. Lowering your property’s assessment does not lower what your home is worth. Assessed Value is for property taxes. Market Value is determined by the real estate market.


Understanding that your property’s Assessed Value and Market Value are not the same thing is very important, especially when evaluating whether you may benefit from filing a Property Tax Grievance in Nassau County or Suffolk County.

What Is Market Value?
Market Value is the estimated price your property would sell for on the open market. It is influenced by factors such as:

  • Recent sales of similar homes in your neighborhood
  • Current real estate market conditions
  • The size, age, and condition of your property
  • Location and neighborhood amenities

Simply put, Market Value reflects what a willing buyer might reasonably pay for your home.

What Is Assessment Value?
Assessment Value is the value assigned to your property by the assessing authority for property tax purposes.
Your Assessment Value is one of the factors used to determine your property tax bill.
Unlike Market Value, Assessment Value is not meant to reflect your home’s current selling price.

Can an Assessment Value Be Incorrect?
Yes. Property Assessment Values can sometimes be based on outdated information, market conditions that have changed, or property characteristics that are not entirely accurate.

Common reasons an Assessment Value may warrant review include:

  • Changes in local real estate values
  • Inaccurate property records
  • Assessment increases that exceed neighborhood trends
  • Comparable properties with lower assessments

Does a Property Tax Reduction Affect My Home’s Value?
No, a lower Assessment Value doesn’t hurt your Home’s Market Value.
One of the biggest myths about property tax reductions is that they lower your home’s value. They do not.

A property tax grievance only affects your property’s Assessment Value for tax purposes. It does not affect your home’s Market Value or the price a buyer is willing to pay.
In fact, a lower Assessment Value can be a benefit when selling your home because it can lead to lower property taxes. Buyers often find homes with fair, lower property taxes more attractive since they reduce the overall cost of ownership.
