Almost every home sold by a turnkey is for long term buy abs hold investors so yes, should you have to sell very shortly after purchase you hope to break even at best. 

You need to do either A-B/B-C with B-C closing after A-B or you can assign contract as long as your sales agreement allows it.

I consider Des Plaines to be an A/B+ area.

If you were to tell me "im leaving school next week" I would probably say its a bad idea.If you were to tell me "im leaving school in 6 months, after I do (A, B, C)" I would say its a good idea.

Morris Invest properties were our first investment and we failed badly so this time we  met a couple of Realtors, Property Management companies and a couple of Bankers/lenders and looked at the properties which were being sent to us and cross checked with all 3 of them to ensure we were not in bad neighborhoods and after carefully reviewing every aspect of the property, we were able to close on a Duplex in a B class neighborhood in Columbus,OH.

I left school with a plan, I like to have plans a, B, C, D.
