Affordable housing is an important policy agenda in Rwanda, where housing challenges are serious. A wide gap between housing supply and demand approximately 1,000 units supplied by professional developers versus 15,000 new units needed in 2017  is exacerbated by a huge affordability gap. In Kigali, the lowest price of a developer-built housing unit is around US$20,000. This is far out of the range of the bottom 50 percent of the income group, who can only afford to rent a unit priced below US$12,000. That is, at least half of the residents in Kigali currently cannot access formal housing options.
