Bring Transparency to Nigeria's Rental Market

The Nigerian rental market is one of the most tenant-hostile in the world. Landlords routinely demand 1 to 3 years of rent upfront, issue no formal leases, and impose arbitrary conditions with no legal protection for tenants. There is no publicly accessible database of comparable rental prices, so tenants negotiate blind. Tenant eviction — often for political or financial reasons — can happen in days with little recourse. Your challenge is to design a rental market information and tenant protection system for Lagos and Abuja. It must provide publicly accessible, real-time rental price data by neighbourhood and property type, enable anonymous landlord reviews, provide a model tenancy agreement in plain language, and offer a low-cost dispute mediation pathway. Submit a service design document (max 12 pages) including: how rental price data is collected and kept current, the landlord review system and its fraud prevention, the model tenancy agreement and how it is enforced, the dispute mediation model, and a plan to index 50,000 rental listings in the first six months. Judging criteria: 35% data collection and pricing accuracy model, 30% tenant protection mechanisms, 20% dispute mediation design, 15% listing acquisition plan.
