Indonesia's economic growth from 2018 to 2022 is volatile; the residential property sector is projected to follow macroeconomic trends. Based on interviews with members of Real Estate Indonesia in the Bali region, sales of the property sector, especially large-type residential housing in Denpasar for the 2018-2019 period, experienced growth but not significantly. In contrast to the 2020-2022 period, it experienced significant growth amid the COVID-19 conditions. This phenomenon was not spared from the role of the developers, who carried out a good strategy regarding consumer behavior amid the economic difficulties at that time so that they were able to boost sales of large-type residential dwellings in Denpasar. This study analyzes the decisions of residential purchasing in Denpasar before and during the COVID-19 pandemic. So, there are two groups of samples for two periods, namely the years 2018-2019 and 2020-2022. The selected samples include 87 respondents of consumers and 60 respondents of developers. Data were analyzed using Smart-PLS using the Multi Group Analysis feature to examine the differences in the analysis results for the two sample groups. Developers were involved as a sample because they were assumed to be able to recognize the preferences of consumers in deciding residential purchasing. The results show a similarity of factors before and during the COVID-19 pandemic, namely promotion and the developer's image, significantly influencing residential buying decisions. Meanwhile, the factor that distinguished the two sample groups was the price factor, which significantly influenced the decision to buy housing before the pandemic, while environmental factors significantly affected the decision to buy housing during the pandemic.
