Abstract
Purpose With a focus on Lagos property market, the purpose of this paper is to examine the factors that influence accessibility to data for valuation and investment analysis in Nigeria. This was with a view to improving accessibility to property data in the market, thereby enhancing investment appraisal practice. Design/methodology/approach Primary data utilized for the study were sourced through the use of questionnaire administered on property practitioners (referred to as estate surveying and valuation (ESV) firms) in Lagos property market. A total of 190 ESV firms were selected using stratified random sampling based on their geographical location. Relative significance index (RSI), frequency distribution and principal component analysis (PCA) were employed for data analysis. Findings A total of 19 factors were identified as affecting accessibility to data. Confidentiality attached to property data by practitioners was ranked as the most significant factor with RSI of 0.81. The next three factors were lack of cooperation within members of professional body (0.79), accuracy of data (0.76) and duty of care to client (0.75), while the least ranked factor was duplication of data set (0.63). All the 19 variables were further grouped into six principal factors using PCA, namely, economic, attitudinal, ethical, legal, administrative and technical factors; with each factor explaining the following variance, 16.75, 16.1, 13.64, 12.78, 10.51 and 7.95, respectively. Practical implications The paper’s results will enable stakeholders to address the challenges to data accessibility in Lagos property market and similar opaque markets elsewhere thereby enhancing property data accessibility and investment analysis. Originality/value The paper is an attempt to examine the factors affecting accessibility to data identified in different studies holistically together in a single study and from the perspective of an emerging property market like Nigeria.
