Read the book "Long Distance Real Estate Investing" by David Greene, then decide if you would like to sign up for an investor academy (which will probably cost hundreds/thousands). 

Also, BP has multiple books on their websites to go in depth of want and what not to do when investing!

How can one, who has only rudimentary knowledge in real estate without any boots on ground experience (read a few books), effectively choose a real estate agent?

I started by listening to rich dad poor dad books.

Congrats on putting the first deal in the books! 

Ask if the brokerage has any books about investing, like FLIP, HOLD, or the Millionaire Real Estate investor. 

However - if you self manage the asset - you're correct that you will have additional responsibilities related to keeping your books fresh, up-to-date, and in order. 

@Tom S.Thank you for the great advice, I will definitely make sure the inspectors check against the code book, its a duplex listed at 69k currently but foreclosure company seems eager to be rid of it, so the price should be fairly flexible.
