Books on apartment investing

[Omer Zulfiqar]

Can I please get recommendations on books you have found helpful for apartment investing? Amazon has an abundance of material. Its hard to know which book is worth the time. I am trying to avoid something that's primarily hype and "why you should invest in real estate...its the best thing since sliced bread" feel to the book. I have the funds to buy apartment buildings, I am simply trying to make sure I don't have too big of a blind spot when I show up to make my first deal.
