I look at a specific property, then the market its in, and I base all my decisions on actual cash flow vs future potential income (and of course how much and how long it will take to get it to its highest and best use)This simple recipe helped me survive bad times and prosper in good times with a great record through 1991 Gulf war, 2001 Terrorist attack, 2008 Great Recession, and the pandemic of 2020. 

Second, Doomsday posters need to refer to history and see how these great cities have come back from devastating setbacks that include natural disasters like major earthquakes or human oriented terrorist attacks.

I have a ghetto terrorist pro tip for you.

External factors often affect the economy, such as the terrorist attacks of 9/11 adversely affecting our economy or even natural disasters.

A fire, a hurricane a terrorist attack etc.. 

Hyper inflation, A world war, a terrorist attack. what?
