[Skunkworks] OT : Kenya's real estate boom fake or real?

I read various articles on the amount of new construction going on and this sector to me is quite baffling. I think the recent report by the CBK puts home mortgages at around 14,000 kenyans. Our borrowing bank interest rates and repayments are still too high compared to incomes. Where are people getting the money to buy/invest into real estate because everywhere you see, some new construction on residetial types is coming up and also being sold quite fast. Property prices have really shot up while earnings have not increased in comparison. So who is buying these expensive properties? Any economist here in skunks KE to add some insights. :-) Rgds.
