The downside is that I have to put in $480,000 Dollars of TI and brokerage fees, but the upside is that they will be putting in 1.5 million to redesign and improve the existing structure. 10 years from now I might have to go through the same thing, but I wanted to give you an example of how things can go wrong at the end of these leases.  

'Thanks, Dan DietzHey Daniel, The IRS has a list of 11 real property trades or businesses that qualify: real property development, redevelopment, construction, reconstruction, acquisition, conversion, rental, operation, management, leasing, or brokerage.

I would start talking to the brokerage houses in Chicago, as they likely rep tenants well into the suburbs, like Bourbonnais appears to be.  

Like Michael noted, I would be reaching out the major brokerage houses and trying to find a role on their office or industrial teams.  

Does anyone have any recommendations for brokerages moving forward?

I'm a licensed broker myself with NAI in AZ, and I have my own brokerage in WA also. 

Thanks  You are likely looking for the commercial meetups in the area, generally I'd ask around at a couple of the larger brokerages in town if there is a meetup you can attend.  

But many major brokerages won't list their properties anywhere but their own proprietary websites.  

I'm not sure about where you would find internships but maybe you could work as an assistant at a real estate brokerage, a real estate investment, property management, or inspection company.  

I'm a broker and investor in NYC and run my own investment brokerage.
