The house is one of basic human needs for living besides food and clothing. To build a house, someone needs a plot of land. But as the population grows in Indonesia and the limited land available, house prices from year to year tends to increase. Rising house prices will have an impact on one’s housing affordability. The problem of housing affordability is also happening in countries other than Indonesia, especially in developing countries. In addition to limited land to build a house, a person's housing affordability can be measured from the other factors. In this study, the author aims to find out what factors housing affordability and measure the effect of each factors. From the results of factors analysis, and testing the validity and reliability there are six main factors that affect housing affordability, including; the growth of sharing economy, environment, price, purchase intention, location and facilities. This research was conducted quantitatively. The data used in this study are primary data obtained from conditional surveys distributed by the author. This study does not focus on the age of respondents but of the 427 respondents this survey has a tendency in Millennials and Generation Z where the respondents do not have permanent residential in private and have a tendency to own and buy a house. The method used in this study is ordinal logistic regression because this statistical method can describe the relationship between response variable (housing affordability) that are influenced by predictor variables (growth of sharing economy, environment, price, purchase intention, location, and facilities). The findings of this study is that the predictor variable that has the most impact is the growth of sharing economy. This situation is caused by the fact that most people who still choose to live in a private residence rather than living in a property that requires someone to share such as a rental house, apartment, or AirBnB even though 54.33% of respondents agree that sharing a house or living space is suitable for the present time. The calculation result shows that a person had to increase his or her housing affordability level by 1,704 times because of growth of sharing economy. In conclusion, the one's housing affordability is influenced by personal choices and then followed by external factors offered by housing developers or property developers.
