Your situation will dictate what is best.
In the many transactions in which I have completed, the purchase was possible, but the property could not be sold without a TIN. This has consequences regarding the method you may choose to purchase.
Again, you need to have a real time discussion with a professional IN CHICAGO.
Best of success to you,
