Millions of Nigerians want to own the homes they live in, but they cannot afford to pay 30% of the asking price up front. They also have to pay as much as 25% interest on the loan they take. In many cases, the money has to be paid back as soon as 5 to 10 years. Cheaper houses are not being built, because banks won't finance them. That means 16 million homes need to be built in Nigeria just to meet demand. But only 50,000 are being constructed each year. Al Jazeera's Yvonne Ndege reports from Abuja.
