The Assessment Office does not prepare deeds.  You need to retain an attorney to have a deed prepared or modified.  We cannot change, add or delete an owner's name from our records unless there is a recorded deed evidencing that change.

As a service to the taxpayers, the Town has made a diligent attempt to maintain and preserve deeds, some of which date back to the 1600’s.

Copies of deeds may be available and can be provided to the owner of the property ONLY for a fee of $.25 per page.  Please note that we may or may not have some of the older historic deeds.

For all others, copies of deeds may be obtained through:

Westchester County Clerk's Office
Land Records Division
110 Dr. Martin Luther King Jr. Blvd.
White Plains, NY 10601

(914) 995-3080

The County Clerk's website indicates:

To search for a land document, visit Westchester Records Online to determine whether the document you are searching for is recorded in the Office of the Westchester County Clerk.  If the document is recorded in our office and you wish to obtain a copy of it, you can pay a daily user fee to view it online, visit our office, or request a copy of the document  by mail.

Sales Data

To determine if an assessment is fair, sales in the immediate neighborhood that are comparable in elements of comparison (for example: style, design/appeal, square footage, age, condition, lot size, etc) need to be identified and analyzed.

The town's sales books (see related links) by village list valid arms length sales to consider.  Market value is what a home should sell for under normal conditions.  This excludes sales whereby a buyer or seller is under pressure to act, possibly as a result of financial distress, relocation, death in the family, divorce, or similar reasons.

Determining market value is an art, not a science; however, the results can be relatively accurate if the right methods are applied and important details are considered.

Unfortunately, finding an "exact" comparable sale is rare.  To account for these differences, the sales prices of the comparables need to be adjusted.  This requires an analysis to determine if these differences would increase or decrease the sales price and by how much.  The adjusted prices of the comparable sales would then be used to the estimate what the subject property would have sold for if all the characteristics were the same.  This is similar to the analysis done by an appraiser.

The New York State Department of Tax and Finance has an excellent webpage on How to Estimate the Market Value of Your Home.  In it they give an example of how comparable sales would be adjusted for different elements of comparison to arrive at a market value estimate.

The New York State Department of Tax and Finance has an excellent webpage on Reassessments.  In it they explain that if your assessment increases, it does not mean that your taxes will automatically will increase.

NYS further explains:

Your taxes may increase, decrease or stay the same.

Market values of properties can increase, decrease or stay the same. The reassessment will ensure that your property is assessed based on current market values.

If your assessment does increase, it doesn't mean that your taxes will automatically increase. If the increase in your assessment is less than the average increase, your taxes will actually decrease. For example:

  • Your assessment increased by 12%
  • The average assessment increase was 15%
  • Your taxes will decrease (assuming your school and municipal budgets remain stable and the tax levies do not increase)

Reassessments don't increase taxes collected by local governments

The assessor is not responsible for taxes - only for assessments.

Months after assessments are finalized by the assessor, school districts, cities, towns and counties determine their tax levies - how much they need to collect in taxes.

The property tax levy is determined separately from the assessments. The tax levy is then distributed over all taxable assessments.

If assessments increase, tax rates should go down proportionally. This is because the tax levy is now being distributed over a broader tax base. If tax rates go up or stay the same, it simply means that the municipality or school district is collecting more in taxes.

Instructions for Using the Sales Books

  1. Check Imagemate Online for your NEIGHBORHOOD CODE on your property
  2. Locate the sales within your neighborhood (those with the same neighborhood code).
  3. Look for the same style  of your house and similar square footage.
  4. Those properties that are most SIMILAR in style, square footage, age, etc. are the ones that would be considered COMPARABLE.
