What advice I have and I'm far from an expert is this. There are some truly experienced folks who share great information. So read, read, read. Conferences are overpriced and are usually just to be ignored, you'll get 100x more from your local real-estate groups.
Start using zillow or redfin, MLS or whatever mass information source you have and start studying a few areas. What are the prices for a 3 bedroom? What are they for sale for and what did they sell for last? Learn how to classify what rents and sells in a few areas and for what. Sure it'll seem random at first, but after a few years. You'll be able to pin point it. A business minded real-estate agent can REALLY help jump start this too.
Once you found an area you like, start driving around there. Sounds crazy, but being in the area in person really does give a lot of information that's hard to classify in the MLS. Notice the cars that are parked and if people that are walking around seem friendly or if young families are there or not. Does it have a lot of high class foodie areas or is it close to a college? Is there we buy gold signs, a Walmart or a lot of franchised business? At the same time start looking at homes "differently". This will start to fine tune "value" for you. Value is important because a great deal per door doesn't make it a great rental, but might for a flip.
Know what gets you going. Do you want to buy and flip? Do you want to buy fix? Are you going to rent them and be a landlord or have someone else landlord it for you? So many options! :)
