Welcome to Bigger Pockets Andrea,
The Bigger Pockets podcast is fantastic and it has a ton of episodes to choose from, It is more detailed about the numbers and specific methods than any book I've read so far the blog is great too.
My personal favorite book is the Millionaire Real Estate Investor by Gary Keller and Jay Papasan, Both of those two have a ton of Real Estate Knowledge and its an interesting book, additionally the audio book is high quality.
Lastly, Like Billy said, start making connections with lenders, investors, and Realtors in your area. Identify exactly what kind of deal you are looking for, exclusively buy and hold? Multi family? Single family? Once you do that you should start looking at real things on the market in the area your interested in and get a feel for what is out there so you know what a good deal looks like, even if the MLS doesn't have the deal you're after it will help you understand whats out there.
