It’s a new year and a new administration at the West Deerfield Township Assessor’s office. We would like to extend our thanks to Tom Healy for his 12 years as Township Assessor and both Joe and Mary for their years of service. While the staff is new, our commitment to serving the West Deerfield Township remains as strong as ever, and we’re excited about and poised to make changes that help our community and its residents.

Andrew Richter, MAI, CIAO is thrilled to be starting as Township Assessor. Andrew brings his 20 years of real estate appraisal experience to the assessor’s office in the hopes of improving the efficiency and effectiveness of the office. With experience both preparing appraisals for and ruling on assessment appeals as an alternate member of the Lake County Board of Review, Andrew has the knowledge and experience to value all types of real estate in the township fairly and expertly.

PRINCIPLES THE ASSESSOR’S OFFICE FOLLOWS. The Township assessors use the same principles, techniques and methodologies as those employed by fee appraisers with only slight variations to accommodate the uniformity criteria of the United States Constitution and the Illinois Constitution.

THE ULTIMATE PURPOSE OF ASSESSED VALUE IS TO APPORTION THE TAX BURDEN. The Assessor is not responsible for deciding the tax burden. That is established by the major taxing bodies. The role of the assessment is to provide a means to divide the tax burden in a fair and equitable manner based on the value of the real estate.

THREE APPROACHES TO VALUATION. The Assessor uses three traditional approaches to appraise property: the cost approach; the market or sales comparison approach; and the income approach. These are standard methodologies in the appraisal industry. Variations in the application of these approaches are necessary because the Assessor is also required to ensure that similar properties have similar assessments. This is known as assessment uniformity.

STATISTICAL TESTING AND ASSESSMENT ANALYSIS ARE INTEGRAL PARTS. As a result, assessors rely on statistical measures much more than fee appraisers. Armed with means, medians and coefficients of dispersion, the Assessor is able to confidently appraise properties at the appropriate percentage of market value and ensure the degree of uniformity in the Township is within acceptable parameters.

YOUR NEEDS MATTERS. If you call the West Deerfield Township Assessor’s office, you’re likely to get Andrew himself on the phone, or one of his close colleagues. It’s part of our commitment to serve the community by being more approachable, available, and attentive. Andrew has lived in Deerfield his whole life, and knows our community and its residents need thorough, individualized attention. It’s a point of pride that our office will now walk people through the process with customized care. We strive to make sure that even in difficult situations, and sometimes stress and confusion, each visitor will leave armed with information and the knowledge that the township understands and supports his or her needs.
