A SHORT HISTORY OF PROPERTY VALUATION MODELS — THE 17TH TO 21ST CENTURY Prepared for presentation at the European Real Estate Society Conference, Stockholm, Sweden, 27 June 2009 Rodney L Jefferies Agricultural Management and Property Studies Department, Commerce Faculty, Lincoln University, Canterbury, New Zealand P.O. Box 84, Lincoln University, Lincoln 7647, New Zealand 1 Overview of Paper • The aim of this paper is to set in context of a history — necessarily short to fit in the scope of a conference paper — concentrating on describing and examining the development of investment valuation models — not the theory beyond that necessary to explain the models in their historical context. • It does deal with methodology — but only to the extent as to how the models fit within the broader investment valuation paradigms of their day and professional generation. • This paper, based on the author’s PhD current research literature review, omits any equations and examples of the models referred to. The citations and references refer the reader to relevant sources for such details and elaborations by the originators of the models. (A Doctoral proposal was presented at this ERES Conference Doctoral Session 1.5 – A generic property interest real value investment valuation model). • Accompanying this paper is a colour chart [Following] setting out the key contributions to income valuation models historically over the last four centuries in chronological order by decades within each highlighted century, beginning in 1600 to the present time. • This shows the contributions of the various authors stratified into those from the UK, USA, and Australia/New Zealand with a brief identification of their key publications or contributions. • It highlights the historical developments in income valuation models set longitudinally against the different technologies available to valuers applying these models in practice. Sections in Paper Introduction History of income valuation thought, concepts, professional practice and standards Historical development of investment valuation models Investment versus market value Firstly, UK property investment valuation models History of models and valuation tables in 16th–18th Century Equated yield models UK rational or logical valuation models Real value models RICS Research report into valuation methods UK Professional response and EY endorsement Real Value Hybrid Model Discounted cash flow “models” in the UK Advanced explicit DCF, arbitrage , split tenant-risk/market risk rate , actuarial, convertible bond and real options models Inter-country comparisons Clay’s 17th Century Valuation Model Based on 30 years purchase @ 3.33% p.a. 4 Sections in Paper Continued Secondly, USA investment real estate appraisal models Capitalization models in the USA – 1930-1960s Split-capitalization models Band of investment models Ellwood’s mortgage-equity model Discounted cash flow (DCF) models in USA Blackadar’s dynamic capitalization model Thirdly, Australia & New Zealand Synthesis of traditional and other models from UK & USA Australian & New Zealand adaptations of DCFs from overseas models DCF model development & standards in Australia & New Zealand Jefferies’ generic real value model Influence of technology on progress Author's slide rule from the 1960's Odhner Mechanical Calculator circa 1935-45 as used by Author in Dunedin in 1964 6 Sections in Paper Continued Fourthly, The parallel influence of technology • This first technological advance arose from the printing press – mass produced ready-reckoners, almanacs and valuation and interest tables from the early 17th Century • Next advance was the introduction of slide rules in 18th — 20th Century • Next was mechanical calculators — invented in 1822 used to 1960s • Next was electronic calculators — invented in 1957 used to present • Next was electronic computers — invented in 1960s used to present • Application of models to multi-tenanted properties • The lag in textbook coverage • “Long live” direct capitalisation! – Progress is inevitable however! • Valediction – This author would propose a real value model for real estate valuation – but “he’d have to say that” – wouldn’t he? • The time-charts Follow: Technology becomes – electronic & then small and portable Vintage Sharp Compet 364R Calculator As used by Author ex 1973 & still on his desk Vintage Compaq Portable II -1986 As used by Author 1986-1995 8 Australia & New Zealand Land Economists & Valuation Model Contributors 1620 1630 1640 1650 1660 1670 1680 1690 1700 1710 1720 1800 1810 1820 1830 1840 1850 1860 1870 1880 1890 1900 1910 1930 1991 - Douglas Scarrett 1994 - RICS 1995 - Gerald Brown 1995 - Alastair Adair et al 1995 - Andrew Baum and Neil Crosby 1995 - Nick French and Charles Ward 1996 - Andrew Adams and Philip Booth 2000 - David Isaac and Terry Steley 2000 - Tony Johnson et al 2002 - Tim Harvard 2002 & 2008 - Alick Davidson 2006 - Andrew Baum et al 2006 - Sarah Sayce et al 2007 - Peter Wyatt 2008 - Andrew Baum and Neil Crosby 2008 - Douglas Scarrett 1980 1990 2000 Kenneth Lusht - 2000 Karl-Verner Schulte - 2001 Dominick Fischer - 2002 Charles Akerson - 2000 & 2009 Tom Whipple - 2006 Appraisal Institute - 2001 & 2008 Richard Reed - 2007 Jeffrey Fisher and Robert Martin 2005 & 2008 1970 Appleby and Westwood 1991 Baillieu Knight Frank - 1992 Jefferies - 1990 Patrick Rowland - 1993 AIVLE - 1993.
