In this paper, the objective of this research was to study the factors influencing the decision to choose condominiums near the sky train stations of the non-registered population in Bangkok using primary data from survey research, which were collected from March 2021 to June 2021 and were estimated by using Binary Logit Model. 
It was found that the factors influencing the decision to choose the condominium near the sky train station at the statistically significant level of 0.01 were age, a negative influence on the probability of choosing a condominium near the sky train station, and divorce status, a positive influence on the probability of deciding to choose the condominium near the sky train station, comparing with those who are single individuals. Additionally, those who have a bachelor’s degree (edu) had a negative influence on the probability of deciding to choose the condominium near the sky train station, compared to those who have education below a bachelor's degree. Moreover, a person who is an employee of a public limited company (occup) has a negative influence on the probability of deciding to choose the condominium near the sky train station compared to civil service careers. Furthermore, the number of private hire cars (freq_taxi) and the housing price per square meter (price_sqm) had a negative influence on the probability of deciding to choose the condominium near the sky train station, but the residence without a pool (no pool) had a negative influence on the probability of deciding to choose the condominium near the sky train station. Factors with a statistically significant level of 0.05 were self-employed persons and other occupations (occup) had a negative influence on the probability of choosing the condominium near the sky train station compared to civil service careers. Likewise, travel time to the workplace by the sky train (time_bts) had a positive influence on the probability of deciding to choose the condominium near a BTS station, and the distance from residence to a shopping mall (dist_mall) had a negative influence on the probability. The factor with statistical significance at 0.10 was travel time from residence to workplace by taxi (time_taxi), which had a positive influence on the probability of choosing the condominium near the sky train station.
