The housing market has seen rising prices and rents since the 1980s. Houses and apartments in the central area are expensive, with houses selling for a million dollars and apartments going for $5000 per month. High prices have spread outward from the central area as owners and renters move out of the most expensive part of the city. Gated communities and shopping malls, built with foreign capital and technical expertise, began to appear in 2006. Urban renewal projects have led in some cases to violent conflict and displacement. The high prices leave incoming refugees with few options for settlement besides illegal shantytowns such as Pakadjuma.
