Ownership and Physical Information
Ownership is determined by the examination of deeds, wills, marriage certificates, death certificates, trusts and other documents evidencing the conveyance of ownership rights to real property.

Estimating the Assessment for a parcel of property

This requires that the Assessor to first estimate the market value of the property being assessed. There are three traditional methods for valuing property:

  • Market comparison approach estimates the value of property by applying a comparative analysis of recent sales that are similar to the property being assessed in terms of physical and locational characteristics.
  • Cost approach or summation approach estimates the value property by adding the depreciated value of all improvements to the value of the land. The cost approach is most useful to estimate the value of specialty properties for which there is no market.
  • Income approach is used primarily for commercial and industrial properties. The income approach estimates value by capitalizing the income generated by the property after deducting charges for vacancy, collection loss and expenses.

Some of the information that may be required for valuation is listed below:

  • Purchase price of the property being valued
  • Price and terms of competing homes in the same market
  • The cost to replace a building or home
  • The rent a property can generate
  • Vacancy and collection loss trends
  • Expenses necessary to maintain the cash flow of a commercial/industrial property
  • Once the market value is estimated, it is reduced so that the assessment is brought to a uniform percentage of the market value of all property in the Town.
