In total, 190 ESV firms were selected using stratified random sampling based on their geographical location, frequency distribution, percentage, and cross-tabulation were employed for data analysis.Findings The results showed that majority of the practitioners (68.1 per cent) were willing to share property data among themselves while 52.6 per cent of the practitioners were in support of data assemblage. The result also revealed the higher the experience of the practitioners, the more they are averse to data sharing. It was also revealed that the bigger firm are more averse to data assemblage than the smaller firms.
