How Assessments are Determined
Board of Assessors
Assessments for residential properties (1, 2, 3 family houses and
condominium units) are typically based on the market approach to
value. This approach incorporates a statistical analysis of property
sales to determine market values as of January 1. This analysis
takes into consideration only those transactions that are deemed
"arm's length", e.g. sales that took place between a willing buyer
and a willing seller, when neither party was under compulsion to
make the transaction. This data is incorporated into computerized
valuation models, which simulates varying market conditions in each
neighborhood and form the basis for residential values.
Assessments for office, retail, apartment and industrial properties
are typically derived using the income and cost approaches to value.
Under the income approach, fair cash value is derived from the
property's ability to generate income. The Assessor examines the
rents generated by office, apartment, retail and other commercial
buildings, subtract operating expenses to achieve a net income, then
divide net income by an appropriate capitalization rate, in order to
derive a market value for each parcel of commercial property.
The cost approach measures the estimated cost of replacing or
reproducing the buildings and improvements on a property - less any
depreciation - plus the value of the land on which the building
stands. The cost approach is mainly employed in determining the
value of special purpose properties.
