1.1 Background to the Study
 
 
It was in 1987, in
 the wake of some well publicized research works by actuaries Hager and Lord that
 Drivers Jonas first sponsored Investment Property Databank (IPD) to carry out
 detailed research into valuation accuracy in the United Kingdom. The Royal Institution
 of Chartered Surveyors (RICS), as the valuers’ professional body, later took
 over the role of sponsor. In doing so, they were adopting one of the principal
 recommendations of Sir Bryan Carlsberg’s Working Party on valuation practices.
 
 
In 1985, Udo-Akagha,
 one of the leading estate surveyors and valuers in Nigeria, while writing a foreword
 to “Guidance Notes on Property Valuation” noted that;
 
 
             “there ought to be no reason why
 two or more valuers valuing the same interest         in a property for the same purpose and
 at the same time should not arrive at
 
 
               the same or similar results if
 they make use of the same data and follow the  
 same valuation approach”.
 
 
  In the same vein, in 1998, an editorial on
 page 2 on “property valuation and the credibility problems” in The Estate
 Surveyor and Valuer, the professional Journal of the Nigerian Institution of
 Estate Surveyors and Valuers stated inter alia that 
 
 
           “the valuation process has been the
 focus of recent debate and controversy both within and outside the profession
 as cases of two or more valuers giving different capital values with wide
 margins of variation for the same property abound”. 
 
 
Comments of this
 nature have led many to ask whether estate surveyors and valuers are
 interpreters or creators of value. From the above statements, it is evident
 that the twin problems of inaccuracy and inconsistency (variance) in the
 valuation practice exist in Nigeria.
 Even in developed countries such as Britain,
 Australia, Canada and USA, the valuers’ estimates,
 methods and processes have been increasingly criticized for over the past
 thirty years as clients seek advice in increasingly sophisticated investment
 markets (Baum and Macgregor, 1992). 
 
 
In the same vein, there
 has also been a focus on the seeming inability of valuation estimates to
 accurately represent/interpret market prices or serve as a security for bank
 loans. Bretten and Wyatt (2002) observed that valuers do not operate with
 perfect market knowledge while valuers in many instances follow clients’
 instructions, analyze available information, make judgments and respond to
 different pressures from stakeholders when preparing a valuation in a market
 atmosphere of heterogeneity. However, the study of valuation accuracy should be
 a continuing one as is the case in the United Kingdom (UK) where the RICS of
 late teamed up with the Investment Property Databank (IPD) to produce
 investigations into valuation accuracy in Britain on a two (2) yearly basis.  
 
 
The effort in this
 work will accordingly be the study of valuation accuracy and consistency and
 the factors influencing their occurrences, to cover a more up to date time
 period with a view to validating/invalidating, expanding and updating the
 results in the pioneering efforts of Ogunba (1997), Ogunba and Ajayi (1998) and
 Aluko (2000). Accordingly, the present effort will be to deal with valuation of
 properties in the Lagos metropolis which is
 regarded as the most active investment property market city in Nigeria.
 
 
 
 
1.2 Statement of the Research Problem
 
 
Property valuation
 performs an essential role in property transactions. It provides advice on
 prospective purchases and sales in addition to supplying material information to
 underpin property lending decisions. Moreover, since the 1960s and 1970s,
 property valuations have been used to proxy the exchange price of property
 investments for performance measurement purposes. This more recent use of
 valuation indices is a major difference between the property performance
 measurements and the performance measurement of other investment media markets
 wherein measurement are undertaken by reference to market transactions. 
 
 
The differences have
 led some analysts to argue against property as a portfolio asset, which in turn
 has led to the under-representation of property in many portfolios. Moreover,
 the lack of confidence in the use of valuation-based indices might be evidence
 that the portfolio industry does not readily accept valuations as accurate
 indicators of prices (and hence returns) in the absence of accuracy studies
 proving that they are proxies for each other.
 
 
Ajayi
 (2003) noted that increased valuation accuracy and consistency are the demand
 of the more sophisticated and enlightened clients in the emerging property
 market of today and the property market has seen remarkable change within the
 past forty years. Europe and the US have witnessed the emergence of
 institutional investors, the management of investments on portfolio basis and
 the recent advent of new property finance methods including securitization and
 unitization. Clients are now getting much more sophisticated and analytical in
 their decision making approaches and therefore increasingly require more
 accurate and consistent valuation estimates from their consultant valuers. 
 
 
While
 Accountants, Stockbrokers and other financial consultants have progressively
 refined their financial analytical techniques to meet and satisfy their
 changing clients’ expectations, it is rather unfortunate that the property
 professionals - represented in Nigeria by the Estate Surveyors and Valuers -
 have been rather slow and lukewarm in their attitudes and approach to the
 required accuracy changes in valuation practice thereby resulting into complaints
 from clients about valuation estimates (Ojo, 2004).
The issue of accuracy is also imperative because the
 profession as it is today is facing stiff competition in all facets of its
 traditional areas of practice, taking into consideration the fact that the
 estate agency aspect of the profession has become an “all comers” affair and
 moreover, that Engineers, Lawyers, Facility Managers and even some stark
 illiterates (“quacks” of the profession) do engage in property management
 functions. At the same time, Quantity Surveyors are agitating to take-over the
 insurance valuation aspect of the profession, whilst Engineers are also seeking
 to be plant and machinery valuers.
