It is like a phonebook alphabetized by street with names and phone numbers.

If you will have an ad in the phone book, they are listed in alphabetical order.

We had him on Episode 11 of the Straight Up Chicago Investor Podcast to specifically talk about the East side and Alphabet letter streets if you want to give it a listen and potentially reach out to him. 

I used to do it for clients, and while in QB, you can do it without using numbers for account codes, doing it alphabetically, most CPA's still used a numerical system, such as account 1000 for cash account 3000 for AR.

(ie. is there a conversion tool from the score that Neighborhood Scout gives to these alphabetical ratings; and is the home classification for the most part just eye balled?)

I've heard a alphabetical ranking system used to describe neighborhoods, I'm not familiar with the scale so I'll just say the neighborhood is middle class.Hopefully this helps.

Fed's alphabet soup of lending facilities (such as commercial paper).

Then I often go to the yellow pages in the market (sort in alphabetical order) and see who has less than 3 branches in your area. 

Also, my list was probably not set up in the order of when they replied but in alphabetical order.

Now you must pay his unemployment bill or face a host of alphabet agencies who are convinced you are the devil incarnate.
