Client influence in property valuation: a scoping literature review

Purpose - The property valuation process involves the property valuer expressing expertise in reaction to a client' instruction. However, there are instances where clients, driven by self-interest, impose their will to influence valuers into returning property valuation figures that are not the true reflection of the valuer's assessment. This paper set out to revisit the issue of client influence in property valuation by conducting a scoping review to establish key findings, gaps, implications and solutions. Design/methodology/approach - In total, 21 articles on client influence published from 1997 till date were systematically obtained from Scopus, Web of Science, Google Scholar and through citation searching and reviewed through a "Patterns, Advances, Gaps, Evidence for practice and Research recommendations (PAGER)" framework. Further analysis and visualisation were performed using VOSviewer software. Findings - This study found that based on the number of studies, the issue of client influence has received empirical attention, which is few and far between, with financial institutions identified as the major culprits in most of those studies. One core reason for this is the stakes involved in the finance sector, which relies on property valuation for loan disbursement and performance measurement. Furthermore, previous studies have focused on identifying the issue through the lens of the property valuer without giving recourse to the client's perspective on what may drive the issue. Research limitations/implications - This study provides evidence that the issue of client influence persists, with some elements of bias in the methodology. Furthermore, the solutions proffered have focused on the valuer and have not been tested to ascertain their effectiveness. Future studies can consider examining the issue from the perspective of financial institutions. Originality/value - This study is one of the first review studies on client influence on property valuation. It is also the first to identify a pattern in client influence studies that points to the issue being perpetuated by financial institutions. Furthermore, it is the first in recent time to reveal how limited study has been conducted in the area as well as the solutions which have neither been tested nor implemented.
