Automated Valuation Models and GIS - Methods, Applications, and Standards in Valuation

Daniel Fasteen, Ph.D., IAAO Research Subcommittee Chairman, CAMA & Systems Manager, Dakota County, MN, US
Paul Bidanset, Ph.D. candidate, IAAO Valuation Research Project Manager

Prior to the Symposium, on Sunday, October 29th IAAO will present a half-day forum covering the latest developments in valuation modeling. In this half-day forum, students will participate in an interactive discussion on automated valuation models (AVMs) and geographic information systems (GIS). An AVM is a mathematical model used to analyze comparable sold properties in order to derive valuations for unsold properties. AVMs along with GIS, which can be used to capture and understand spatial relationships among phenomena, can be used together to discover a new level of insight into deriving valuations and improving performance.

The forum will be presented by IAAO Research Subcommittee Chair, Daniel Fasteen, Ph.D. and IAAO's Valuation Research Project Manager and Ph.D. Candidate Paul Bidanset. They will explore basic concepts and demonstrate applications of methodologies used in building valuation models using industry practices. The application of GIS in order to account for location effects will also be addressed. Additionally, a brief discussion on standards regarding AVM concepts will also be facilitated.

Topics covered will include:
• Types of Automated Valuation Models
• The life-cycle of building AVMs (and how to get started)
• Compiling and cleaning data
• Selecting appropriate AVMs (Model specification)
• Variable selection and calibration
• Enhancing AVM performance using GIS
• Interpreting AVM outputs for valuation adjustments
• Visualizing AVM output
• Measuring performance and improvement using ratio studies
• AVM Standards

Paul Bidanset currently serves as the IAAO's Valuation Research Project Manager.  He is in the final year of his PhD candidacy at Ulster University in Belfast, Northern Ireland, where he has developed a new AVM for mass real estate appraisal under the supervision of doctors Billy McCluskey, Peadar Davis, and Michael McCord. His expertise primarily focuses on using GIS and modeling to improve valuation accuracy, uniformity, and defensibility for government property taxation. He's been published in journals and mass appraisal textbooks across the globe, and is the 2017 co-recipient of the IAAO's distinguished research award and the Lincoln Institute of Land Policy's C. Lowell Harris Fellowship. 

Daniel J. Fasteen, Ph.D. is the CAMA and Systems Manager for the Dakota County (Minnesota, USA) Assessor’s Office. Daniel has been in the property valuation profession since 2010 where his interests include automated valuation models (AVM’s), integration of GIS and CAMA technology, as well as technology adoption in the Assessor work environment. Dan has a Master’s degree in Geography and a Ph.D. in Research Methodologies and Applied Statistics, both from the University of North Dakota. Daniel currently serves on the editorial board of the Journal of Property Tax Assessment & Administration and is also the chair of the IAAO Research Subcommittee.

Achieving Successful Implementation of Value-based Property Tax Reforms

Richard Grover, Senior Lecturer, Department of Real Estate and Construction, Oxford Brookes University, UK
Aanchal Anand, Land Administration Specialist, World Bank, US

This presentation will highlight the results of a project carried out in 2015 by the World Bank and FAO to identify the lessons learned from property tax reforms and good practice that could be shared. The research was primarily based on eight country case studies of emerging European economies (Albania, Kazakhstan, Lithuania, Moldova, Poland Serbia, Slovenia, and Turkey at varying stages in the development of value-based recurrent property taxes. The Netherlands, which has a well-developed mass valuation system, was included as a comparison.

The presenters will identify the key technical and institutional arrangements needed for successful property tax reform, the comprehensiveness of property registration, the quality of transaction price data, the extent to which the valuation infrastructure meets internationally-recognized standards, and the quality of tax collection systems and what can cause well-designed reform programs to fail.

Richard Grover is currently a part-time Senior Lecturer in Real Estate in the School of Built Environment at Oxford Brookes University teaching real estate economics and property valuations mainly on programs accredited by the Royal Institution of Chartered Surveyors. Before retiring and taking up this part-time appointment, he was assistant dean of the faculty.

Large Scale Land Acquisition, Land Transfer Standards and Fair Compensation: Is Mass Valuation the Way Forward?

James Kavanagh, Land Group Director, Royal Institution of Chartered Surveyors (RICS), London, UK

Large scale acquisition of land, and fair compensation for infrastructural development is a growing issue in low/middle income nations and a source of concern for international development bodies such as the World Bank and UN agencies. Many much needed regional and national infrastructures can be held back or even abandoned due to land issues. Drawing on current RICS research and other sources, Mr. Kavanagh will explore how eminent domain/compulsory acquisitions work, or do not work in some nations, how land valuation/appraisal is a core component of fair compensation, and how mass appraisal might be utilized when market comparable information is scarce.

Why Taxes Matter

Peter Jongkind, Program Director, VGN International (Netherlands Association of Municipalities), Netherlands
Having no access to clean water, homes without electricity, or children without disease-preventing vaccines, in many countries still is a fact of life. Like them or not, taxes pay for these public services. VNG-International developed a methodology to assist municipalities to better mobilize their own resources, to empower them to take command of their own development again, and to restore trust, commitment, co-operation, and coordination between local government and the society.

The session will introduce the attendees to the different components of the methodology and the results that can be realized; it will make them aware that taking into account the interests of often excluded citizens combined with supporting the municipality with capacity building and availability of modern IT tools can lead to improved revenues and better services.

Peter Jongkind is Program Director, VGN International (Netherlands Association of Municipalities), Netherlands.After his psychology studies in Amsterdam and some years of work in the field he worked for five years as a researcher at the Vrije Universiteit (Free University) of Amsterdam.

Since last year he is working as program director for VNG International (the international department of the Association of Municipalities in the Netherlands) to develop and implement concepts and services to improve local tax revenues and public services.

The Tension between Legislation and Common Valuation Principles in the Netherlands

Marco Kuijper, Strategy Developer, Netherlands Council for Real Estate Assessment, Netherlands
Ruud M. Kathmann, Manager, Netherlands Council for Real Estate Assessment, Netherlands
Ben Bervoets, Non-residential Property Valuation Specialist, Netherlands Council for Real Estate Assessment, Netherlands

The tension between legislation and common valuation principles in the Netherlands. The appraisal for property taxation in the Netherlands is regulated in the act for real estate assessment, which states that the market value is the basis for taxation.

In disputes on the value the tax judges expect an unachievable accuracy in the determination of the market value, continuously forcing assessors to overrule the valuation models. In our presentation, we will elaborate on the challenges that emerge from this practice and we explain how we deal with this situation.

Marco Kuijper completed his study geodetic engineering at the Delft University of Technology where he graduated in 2001. In 2006 Marco became a certified internal auditor after completing a study on this discipline at the Erasmus University Rotterdam. At the Netherlands Council for Real Estate Assessment one of the main tasks of Marco is developing the organizational strategy.
