Exposure Draft - Draft of Personal Property Standard

The IAAO Personal Property Standards Task Force has reviewed the Personal Property Standard and has released a version for exposure to the membership. The draft revised standard is available to download, view the proposed changes, and submit comments by July 1.

Succession Planning Toolkit

IAAO has created a Succession Planning Toolkit to serve as a succession planning guide specifically for valuation agencies. We created the Toolkit to help our members incorporate leadership development within their strategic planning efforts since most offices are facing a large number of employees retiring in the near future and will need to cultivate our next generation of assessment industry leaders. The toolkit is available to download at www.iaao.org/successionplanning.

New Big-Box Course

As part of its Critical Issues Series IAAO has developed a Commercial Big-Box Retail online course to explain what big-box retail (BBR) properties are, why BBR valuation is important in today's world, and why it is challenging.  The 2 hour CE course, based on the "Commercial Big-Box Retail: A Guide to Market-Based Valuation" paper published by the Special Committee on Big Box Valuation, identifies the key issues involved in BBR valuation and covers the concept of real property rights and definitions of value.

Find the resources you need in the library

Looking for an IAAO resource? Find all of our internationally recognized publications, standards, and periodicals here. Members have full access to the IAAO Library as well as AssessorNet, our member networking tool.

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.
