There are plenty of buildings available for you to renovate and won't cost you nothing but an investment of hard work and very little money. However, these buildings are reserved by Taliban for NGO's and those directly involved in ending the war on the borders of the Emirate. Alternatively, you may purchase land once you have become a citizen of IEA and build your own house. Some of the finest houses can be built from the resources that are readily available inside of IEA, such as marble and fine wood. The costs to build will vary, but is usually one-third of what you would spend in the U.S. and Britain.
Transportation is very inexpensive.
There are many business opportunities and plenty of resources in the Islamic Emirate of Afghanistan. However, you will have to roll your sleeves and work hard. There are plenty of factories that were abandoned during the war and could use savvy, entrepreneurial talent to revitalize them. Usually NGO's are funded by wealthy buisnessmen from overseas and philanthropists who fund projects based on certain proposals that they recieve. One of the biggest projects that is going on right now is the demining project which is clearing the mines left from the Russian war.
