Various theories were conceptualized from over 12, 000 literature materials garnered and collated from electronic libraries. Starting from germinal socioeconomic theories-Adam Smith invisible hand theory (1776/1776b), Ricardo (1964) substitution theory, and seminar stakeholders' theories were conceptualized and expounded in alignment with how affordable housing affects middle-income population in Abuja, Nigeria. Within the context of this book, middle income population was nebulously defined; however, research shows that the lack of affordable housing affects middle income earners worldwide.How technological situational happenstances are imperatively, significantly, and inextricably intertwined with the real estate industry is congruently explained. Effective and efficient communication, management, leadership, infrastructures, and economic variables are at the core of affordable housing in Abuja. Literature review used in conceptualizing and crafting this book illuminates the need for stakeholders to be engaged collaboratively, synergistically, and seamlessly in filling the gap that will result in affordable housing in Abuja. The stakeholders' engagement in filling the housing gap could be horizontal or vertical. Stakeholders are the governmental agencies, financial institutions and the private sector. The collaborative efforts of the stakeholders and its significance to leadership remain the centerpiece of this book. Corresponding efforts of the stakeholders internally and externally in filling the housing gap in the sub-Saharan African cities are equally advocated. Housing in Sub-Saharan African Cities published 2007 in the United States remain a bestseller that supports and complements this current book.
