1. The RAR is a measurement of assessed values for 1, 2, and 3 family homes within a municipality. If you divide the Assessed Value of a home by its Sales Price you compute an Assessment Ratio. Each year New York State computes an Assessment Ratio for every sale of residential homes within each Municipality and sorts those ratios from from least to greatest. The median ratio is selected as the overall RAR for the Municipality.
2. The LOA is the locally stated percentage of full market value at which properties in that municipality are assessed. New York State Law requires all real property to be assessed at a uniform percentage of value and full market value is used as the measuring tool for this purpose. A LOA of 100% means properties are being assessed the same as their full market value.
3. Each year New York State calculates an equalization ratio for every municipality. This rate is used to maintain equity in the apportionment of taxes when the taxing jurisdiction crosses municipal lines, such as for county or school taxes. The ratio is calculated by taking the total assessed value of the municipality and dividing it by New York State's estimate of full market value. The table above shows the most current Equalization Rates for Oswego County. Historical Rates are available online through New York State.
