I looked at the listing on Zillow and really only saw one issue, though it may be a big one.
The description says 2-1/2 car garage. It's fairly well detached from house and not especially convenient. Also, there's no driveway leading up to that garage. The listing pics show a "dual rut" gravel driveway that ends at the rear of the house.
So, from a potential buyer's perspective, they're likely seeing these expenses on top of the acquisition costs: pave the driveway from the curb to garage (low guesstimate: $10k) and possibly add a car port near the back door to the house to make unloading groceries, etc. more convenient.
The description says "Basement: None". However, the pics suggest a crawl space (block foundation) for plumbing, ductwork, etc. This may confuse some potential buyers. May seem like a small thing ... remember: "the confused mind always says 'no'."
State St. is a major artery - lots of traffic, and the yard is not fenced at the moment - not "family friendly". This represents another potential post-acquisition expense.
The room(s) at the front of the house suffer from "big blank wall syndrome". Added windows might have been a good idea (selling point to let light in).
Judging by where Google shows the lot lines, you may want to consider separately selling the parcel where the garage currently stands, build a new attached garage at the rear of the house. Alternately, on the second parcel, you could take that garage down, put up another house with a detached garage to make better use of the land.
I'm not familiar with Cook County's on-line tax system (wonder if there's a GIS for it?). However, I'd want to verify that the tax amount stated in the Zillow listing represents both parcels. If not, that could be a "knock out" factor for potential buyers. Folks aren't hip on the idea of paying taxes for land which sits largely unused or just to provide a place for the garage to stand. Zillow also shows a triangular parcel east of the other two. Not sure about taxes, etc. for that. Might be worth looking into - I did, others might, also.
