The demand for housing in Indonesia continues to increase, particularly among the millennial generation. However, a contrasting trend is observed with one prominent housing developer, Mansion Nine, which has experienced a decline in sales over the past few years. This highlights the urgency of understanding the factors that influence the purchase intention of millennials, especially in Surabaya. This study aims to analyze the effects of location, price perception, and house design on the purchase intention of Mansion Nine's landed houses among millennials in Surabaya. This research uses an explanatory quantitative approach. Data was collected through an online questionnaire involving 220 millennial respondents who are familiar with Mansion Nine's housing products. The data analysis technique used is multiple linear regression, with the assistance of SPSS software version 26. The results indicate that location, price perception, and house design have a positive and significant impact on purchase intention. Strategic locations, competitive prices, and attractive house designs and types are the main considerations in influencing millennials' purchase intention for landed houses. The implications of this study provide insights for housing developers to design more effective marketing strategies to attract millennial interest, focusing on selecting strategic locations, setting competitive prices, and offering house designs that match their preferences
