This is a very broad question that will result in mostly broad answers. I would say to first decide if you are wanting to invest locally, or out of state. Once you have made that decision, start connecting and discussing with local real estate investors and agents in that area to start to better understand the demographics of the area. Find out where the A, B, C, and D areas are of that town, and start to form a criteria of what you are looking for in a property and where that property should be located.
People tend to say that Class D areas are risky due to the properties usually having many issues, and Class A areas can be difficult because most properties won't have any value add projects available for forced appreciation/sweat equity.
It's extremely possible to start investing locally or out of state, but regardless of your decision, the most important thing is to do heavy research into the area, and creating a team that will help you operate your investments.
