Once you polish up the hard wood floors, fix up the bathroom and kitchen and give it a good paint it looks a million bucks. 

My dad lived there in the the late 70s and early 80s in a boarding house for Polish immigrants.

And like all big cities of the mid west and East.. these were very divided by nationality where did the Grandparent immigrate from.. the Germans lived here the Irish lived there the Polish lived here the Italians there.   

Rather than staying in and polishing the tools you've gained- go out and use those tools! 

Or how you say in polish, "the ones that don't take risk, don't drink champagne."

Honestly I'd recommend saving your money (Please don't hate me BiggerPockets) and developing the calculator on your own in excel you'll learn so much more, and it really is just as good, it just isn't as polished. 

OK you might lose a month or 2 in rent and some cash to polish the place but that might more than pay for itself in the selling price.

I made these places really nice by polishing, painting, repairs, and landscaping.

You not only have to find the "diamond in the rough", you have to polish it.
