International Association of Assessing Officers (IAAO) maintains technical standards that reflect the official position of IAAO on various topics related to property tax administration, property tax policy, and valuation of property including mass appraisal and related disciplines. These standards are adopted by the IAAO Executive Board.IAAO assessment standards represent a consensus in the assessing profession. The objective of the IAAO standards is to provide a systematic means by which assessing officers can improve and standardize the operation of their offices. The IAAO standards are advisory in nature and the use of, or compliance with, these standards is purely voluntary. If any portion of these standards is found to be in conflict with the Uniform Standards of Professional Appraisal Practice (USPAP) or state laws, USPAP and state laws shall govern.IAAO technical standards are intended to guide property tax assessment officials, tax policy analysts, and administrators. Similar issues arise in any nation's property tax systems. IAAO standards can provide guidance internationally. However, certain sections of these standards apply primarily to the United States and Canada, where the power to tax property is assigned to state, provincial, or territorial governments.

This book addresses several problems related to automated valuation methodologies (AVM). Following the non-agency mortgage crisis, it offers a variety of approaches to improve the efficiency and quality of an automated valuation methodology (AVM) dealing with emerging problems and different contexts. Spatial issue, evolution of AVM standards, multilevel models, fuzzy and rough set applications and quantitative methods to define comparables are just some of the topics discussed.

This book will teach the readers the wide-ranging alternate applications of AVMs outside of residential modeling - from the universe of Commercial modeling to REO and Foreclosure modeling to MLS-based data modeling to Stress Testing Mortgage or Assessment Portfolios using Challenger AVMs, etc. Also included are many sought-after topics like Excel-based modeling, Forward Sales Sampling to minimize sales chasing, and the proper process to Evaluate a Vendor or Vet a Consultant.

This monograph critically reviews and updates real estate valuation theory, which is based on neoclassical economics, in light of developments in heterodox economic theory. Building on a comprehensive historical account of the evolution of value theory, the book uses new institutional economics theory and critical realism as lenses through which problems in standard valuation theory and practice are expatiated, and as the foundation for an alternative theory. The new theory is employed to explain major problems in real estate valuation that are beyond the capability of the standard theory, such as price bubbles in real estate markets, anchoring bias, client influence and valuation under uncertain market conditions.
