This study aims to analyze the impact of housing demand perceptions on housing stability and quality of life, mediated by housing price stability expectations. While previous studies have focused on the relationship between macroeconomic factors and housing prices, empirical research on the psychological influence of housing demand on housing stability remains limited. To address this gap, a survey was conducted with 500 adult residents in Seoul, and structural equation modeling (SEM) was utilized to examine the causal relationships among economic factors, real estate policies, living SOC, housing price stability expectations, housing stability, and subjective quality of life. The results indicate that economic factors and living SOC significantly influence subjective quality of life and housing stability through housing price stability expectations, whereas government real estate policies did not show statistically significant effects. These findings suggest that housing policies should go beyond short-term market interventions and consider macroeconomic stability, the expansion of living SOC, and the enhancement of policy credibility. Ultimately, long-term and predictable policies that reflect the psychology and expectations of housing demand are essential.
