Lae, the second-largest city in Papua New Guinea, has witnessed a significant rise in rental property prices over the last ten years, causing a strain on the finances of many of its citizens. Various factors, such as population growth, a shortage of formal housing, rising construction costs, and limited access to housing finance, have contributed to this sharp increase in rent. The rise in rental costs has made it increasingly difficult for residents of Lae, particularly those from middle and lower-income backgrounds, to find affordable housing. Currently, over thirty percent of households spend more than thirty percent of their income on rent, which is extremely unaffordable housing. Additionally, an increasing number of Lae’s population faces the risk of homelessness and displacement due to the inadequate supply of housing available to them. This case study aims to explore the primary reasons behind the significant increase in Lae’s rental housing costs over the past decade. It will examine the impact on different communities and socioeconomic groups and highlight the gaps in legislation. The study will provide valuable insights on how the government, developers, landlords, and other stakeholders can work together to improve the affordability of housing in Lae. With a focus on excessive rent, this analysis seeks to establish a data-driven foundation to address this pressing issue, negatively impacting a large portion of Lae's population. By working together, the community can find innovative solutions to this issue that benefit everyone and we hope that this study will serve as a catalyst for positive change.
