Variance in residential property valuation in Lagos, Nigeria

Purpose Quantitative commentaries in the UK, Australia and other developed economies have generally suggested a high level of valuation accuracy. These important findings need to be developed in other parts of the world to facilitate cross‐border property business transactions which globalization promotes. In countries like Nigeria where the property market and valuation practice are just evolving, the one‐to‐one relationship between valuations and transaction prices observed in more developed economies may not necessarily hold. This paper aims to focus on these issues. Design/methodology/approach This paper reviews major empirical studies on valuation accuracy with particular reference to the methodology and statistical analyses employed, the results obtained and their limitations. The paper also includes the results of an empirical study on valuation accuracy involving 250 residential properties in metropolitan Lagos, Nigeria. The paper employs error metric and econometric statistical techniques. Findings The study reveals, among others, that residential property valuation in Lagos metropolis exhibits inaccuracy below industry's acceptable minimum standards. Practical implications The credibility problem engendered by inaccurate valuation has far reaching consequences on the relevance and future of the valuation profession in the study area. Greater collaboration between professionals and academia in research, information procurement and analysis, improvement in valuers' task environment, a well articulated and encompassing mandatory national valuation standards incorporating effective enforcement machinery are some of the suggested remedial measures. Originality/value The study draws attention to the potentially grave implications of this result on bank solvency and the attendant negative impact on various aspects of the economy.
