Indeed, they are currently building a new capital

In our culture, real-estate is as secure as gold. In the last 7 decades, the country suffered from wars, many uprisings, and economical instability, but you will never find someone bought a property for 500K and sell it later for 300K. Ironically, after these types of events the prices shoot up, because people find keeping liquid money is a big risk. Unlike many western countries where properties lost significant amount of their values like in 2008 crash.
