Books to buy as a beginner REI

[Whitney Robert Caldwell]

I have recently acquired my first SFH buy and hold. The Cashflow and CoC RoI is about 1/3 less than I presumed it would be. I have learned a great deal about my market by actually investing into real estate. However, I would like to prevent making some of my previous mistakes on my next purchase. Being that I have no mentor to learn from I suppose I can teach myself. That said any recommendation of books for SFH buy and hold inventors would be helpful. I have already read the bigger pockets 'Rental Property Investment Book' and a book by Tom Wheelwright 'Tax Free Wealth'. I suppose I would like to delve a little deeper into how to find actually good deal outside of Zillow, Redfin and Realtor.com Any books that you can recommend would be greatly appreciated. Happy Holidays!
