What's New!

IAAO has released the association's position paper on valuing big-box stores. The paper, "Commercial Big-Box Retail: A Guide to Market-Based Valuation," was published by the Special Committee on Big Box Valuation, under the direction of the IAAO Research Subcommittee and IAAO Executive Board. The paper was released on Tuesday, September 26 at the IAAO Annual Conference in Las Vegas and was reviewed during the program "The Research and Findings of IAAO’s Big Box Task Force." The IAAO position paper focused on the key elements that assessment officials consider when addressing the challenges of Big Box store valuation. This Task Force was overseen by the IAAO Research Subcommittee. 

IAAO held a Town Hall at the Annual Conference in Las Vegas to review changes to committee and volunteer opportunities. For additional information on the changes and how they impact individual committees, please see the video recorded by President Randy Ripperger, CAE and see the committee diagram

To assist members in providing information about the assessment process, IAAO has  developed a public information brochure, Understanding Your Assessment, explaining how the value of property is estimated and what causes it to change. Copies of the brochure are available to purchase online in quantities of 50 at $17 per each 50.

Information on candidates and a constitutional amendment are available to view. The election will be electronic only and starts November 1.

The guide on intangibles developed by the IAAO Special Committee on Intangibles is now available for download. See the Technical Standards page for more on Understanding Intangible Assets and Real Estate: A Guide for Real Property Valuation Professionals.

The library recently released two new subject guides. The Sharing Economy Subject Guide provides links to articles, reports and websites with information on this new part of the economy. On landfills, there are two different ways to look at the valuation of landfills and the subject guide provides sources on both the appraisal of the landfill itself and also the impact on the surrounding properties.
