I would strongly encourage you to engage with the Global Real Estate Forum of the Chicago Association of REALTORS. This group of brokers works specifically with clients who invest overseas and with foreigners who wish to invest in the USA.
Check http://www.chicagorealtor.com/associations/6001/global/ for more information about this group.
I have been a member for over ten years and have capitalized on opportunities from many corners of the world as a result. Many of the broker-members of the Global Forum are also members of the Certified International Property Specialists (CIPS) network of NAR.
The majority of these brokers speak a language other than English and have life experience abroad. It is a diverse and engaged group!
If you plan to visit Chicago, contact the Chicago Association of REALTORS for information about upcoming meetings and events of our group. We'd be delighted to meet with you!
