Real Estate Online Platforms (REOPs) are used for conveying real estate and property-related information to potential users (buyers, renters, or sellers). The information leveraged through REOPs supports these users in reaching conclusive rent or buy decisions. Despite their promised utility, user perception about accepting online information through REOPs is unexplored. Using a comprehensive questionnaire and data collected from 65 users, the current study captures the users’ perception of REOPs. Risk, service, information, system, technology adoption model (RSISTAM) is proposed comprising of seven users’ perceptions: risk (PR), service quality (PSEQ), information quality (PIQ), and system quality (PSYQ) from the information systems success model, and usefulness (PU), ease of use (PEU) and behaviour to accept (BAU) from TAM. The results are analysed using the decision making trial and evaluation laboratory (DEMATEL) approach, which shows that PIQ, PSEQ and PEU are the causes and PR, PSYQ, PU and BAU are the effects. Among the criteria, the order of prominence is PEU > PSEQ > PIQ, and for net effects, the order is PU > BAU > PSYQ > PR. For addressing the causes, the REOP managers must provide more transparent, high quality and voluminous information to the users, focus on the system, services, and information qualities, and add more enjoyable, immersive and easy-to-use content through REOPs. This study contributes to the body of knowledge by exploring user perceptions and proposing methods to improve the quality and reliability of REOPs in line with Real Estate 4.0 and industry 4.0 aims.

房地产在线平台 (REOP) 用于向潜在用户（买家、租房者或卖家）传达房地产和财产相关信息。通过 REOP 所利用的信息支持这些用户做出决定性的租金或购买决定。尽管它们承诺了效用，但用户对通过 REOP 接受在线信息的看法尚未得到探索。本研究使用综合问卷和从 65 位用户收集的数据，捕捉了用户对 REOP 的看法。风险、服务、信息、系统、技术采用模型（RSISTAM）被提出，包括来自信息系统的七个用户感知：风险（PR）、服务质量（PSEQ）、信息质量（PIQ）和系统质量（PSYQ）成功模型、有用性 (PU)、易用性 (PEU) 和接受行为 (BAU) 来自 TAM。使用决策试验和评估实验室 (DEMATEL) 方法分析结果，表明 PIQ、PSEQ 和 PEU 是原因，PR、PSYQ、PU 和 BAU 是影响。其中，突出的顺序是PEU > PSEQ > PIQ，对于净效应，顺序是PU > BAU > PSYQ > PR。针对原因，REOP管理者必须向用户提供更加透明、高质量、海量的信息，关注系统、服务和信息质量，通过REOP增加更多趣味性、沉浸感和易用性的内容。本研究通过探索用户感知并提出方法以根据房地产 4.0 和工业 4.0 目标提高 REOP 的质量和可靠性，从而为知识体系做出贡献。
