What should I be reading right now from BP pertaining to BRRRR?

[Sam Lopez]

Hi All, so I've got some Audible credits I need to use before I close that account. I'm very interested in BRRRR'ing, and property management. I have a few duplexes ATM and am BRRRR'ing two of them. Please share what you've recently read or what you'd recommend for someone in my situation. I've already listened to quite a few, but I'd like to know what you'd recommend. Thank you!
