@Dereck Mills books, videos, & podcasts are the building blocks for any newbie so right there you're already off to a great start. Some progressive next steps:
1. Start analyzing properties - get a feel for how to analyze good deals so that you know the price points your chosen neighborhoods that are good deals. It will take time and you may not have even chosen neighborhoods yet but analyzing deals in multiple areas will help you narrow down where good and bad deals are - thus, helping you pick the areas to analyze further and jump on should a good deal come available
2. Talk to a mortgage broker - I say this before you get pre-approved. There are a lot of questions you'll have once that process gets going and when the time comes for you to submit an offer you likely won't have time to ask all of them. The sooner you start the mortgage/financing discussion the more comfortable you'll feel. Chalk it up as learning more information about the whole process and helps you start building your team!
3. Save money and pay down debt - there are many different strategies but I found it useful to pay myself first (Read Richest Man in Babylon if you haven't). There higher % of your income that goes to you the better!
4. Go to Local Real Estate Investor meet ups. Philadelphia has a huge REI Group so google that and start going to simply be around and get comfortable talking real estate.
Education is the basis but you also don't want to get stuck in analysis paralysis. Hopefully some of these steps can help you move the needle forward over the next months and get you prepared to buy your first property!
