This intensive two-day workshop is designed for both appraisers and valuation modelers who are involved in the development of residential property assessment values. Through an engaging, hands-on format, participants will work within a guided simulation using R to explore and implement a proven case study focused on market-based valuation techniques.

Leveraging real-world residential sales data, attendees will learn how to derive time adjustments and apply multiple regression analysis to quantify and interpret key property adjustments. The workshop emphasizes a structured, iterative approach to modeling, leading participants through the creation and comparison of additive, quadratic, and multiplicative models. By analyzing and interpreting the results, students will gain insight into the distinctions and advantages of each modeling method.

By the end of the session, participants will have developed a solid understanding of how to create and explain valuation adjustments and predictive models in a mass appraisal context. Attendees will leave with the R syntax, skills and confidence needed to apply these methodologies in their professional practice.
