ARTICLE INFO ABSTRACT Article history: The purpose of this paper is to determine the variances and significance of variances in Received: 7 July 2014; capital values of properties in metropolitan Lagos of Nigeria resulting from anchoring and Received in revised form: adjustment methods used by independent valuers in carrying out valuations within the scope 20 September 2014; of standard and non-standard anchoring paradigm. Valuation problems of ten properties Accepted: 1 October 2014; were presented to 144 valuers in metropolitan Lagos to solve; but 104 (72.2%) participated in the experiment; and the One –sample t-test was used to test the variances. The significant Keywords P were all 0.00 for the ten properties; and this means that there are significant variances in Adjustment, Anchoring, estimates of property values determined by the valuers in the area of study. Crises in Capital values, Heuristics, financial markets in Nigerian economy in the ending years of 2008 resulting from poor Independent valuers, property valuation and unreliable values of collateral properties advised by independent Residential property, Variances. valuers have heightened the need to find remedial measures to mitigate wide variances in the property values. Also, wide variances in capital values of real properties will result to clients losing confidence in values advised by valuation professionals. © 2014 Elixir All rights reserved Introduction obtained from estate agency firms that valuers are not staff of Variances in capital values of a property determined by (Wyatt, 2003). Due to the unfamiliar nature of some markets to independent valuers are generally accepted to be permissible in some valuers, anchors are sourced externally from the the valuation profession. What have been unacceptable are wide experience and knowledge of some local experts familiar with variances. Recently, the profession has come under attack by the property markets (Diaz 1997; 2002). Epley (2004) gave two those that make use of valuation reports such as banks and explanations why problem solvers base their judgments on sometimes courts. The policy of majority of banks in Nigeria is anchors provided by these experts. One is that problem solvers to brief multiple valuers to report on the value of any property usually take the anchor as a hint to the correct answer based on brought as collateral by loan applicants before advancing loans. the conversational logic that experts only provide relevant Variances in capital values seen in valuation reports have led to information. Second is that these professional services providers loss of confidence by the banks and created embarrassment to are more likely to stay close to the anchors because they have no the profession. A report of a select committee of the Nigerian previous knowledge to aid in adjusting it. Reinforcing the need Institution of Estate Surveyors and Valuers (1998) highlighted for local experts, Raheem (2005) also opined that failure of the problem of wide variances in capital values of various problem solvers to involve these experts in solving problems in classes of properties valued by their members. This paper unfamiliar areas may cause lack-of-participation error in studied the variances in capital values, significance of such outcomes. variances, and ascertained whether anchoring and adjustment Non-standard anchors (Non-specific anchor or Intuitive heuristic behaviour, and the anchoring and adjusted amounts in Approximation) the market evidence method of valuation have significant Non-standard anchors are sources of anchor data other than contribution to variances in property value opinions, and the market price anchors. Worth knowing is that market suggested remedial measures. uncertainty to valuers evokes these anchoring behaviours. For Review of Related Literature example, Levy and Schuck(1999) found that student valuers in Sources of Anchor an experimental context were influenced by previously Sources of anchors can be classified into: undertaken valuation task. Also, Diaz and Wolverton (1998) The Standard Anchor or Market Evidence Data observed that United States appraisers anchor to their own Standard anchors refer to recent prices of similar properties previous estimates of value. Anchor data could also be on used in the comparison method of valuation. These anchors previous price experience of subject property (Aycock, 1999). could be internally or externally generated anchors; or the Tversky and Kahneman (1974) opined that decision makers market prices data obtained from any of the branches of the have implicit tendency to spontaneously generate their own estate firm which a valuer executing a valuation task works independent hypotheses about states of the world based on for(Diaz, 1990; Wyatt 2003). The internally sourced kind of available raw data and to anchor their final decisions onto these standard anchors refer to the market prices of similar properties initial hypotheses. Diaz and Hansz’s (2000) observed that obtained from internal records of estate agency firms; while the United States experts operating in unfamiliar market anchor on external anchors are recent market prices of similar properties knowledge of pending price (or uncompleted contract prices) of Tele: E-mail addresses: [email protected] © 2014 Elixir All rights reserved 27509 Obinna LUmeh et al./ Elixir Inter.
