Contract for Deed - Illinois - Get around?

[Rachel Latham]

Hi there - my landlord has notified he wants to sell - I don't want to move. I am about a year away from being able to buy on my own, and was looking at contract for deed as an option. While learning about this, to hopefully propose it to him, I found out he took out a mortgage on the house about a year ago (was previously paid-off). Learning more - looks like DOS clause could get in the way of my contract plan. Is there anyway around this that I just haven't found yet? Thanks for your help.
