Hey Connor,
As you already know, some markets work better than others for different investment strategies. When it comes to long-distance investing, prior to identifying the MARKET you want to invest in, should be IDing what TYPE of investment property you're searching for (ie. LTR vs. STR, fix n' flip, BRRRR, single-family vs. multi-family, price range, etc.). Once you've answered that question, its much easier to choose a market that better supports that investment type.
Assuming you've already ID'd your investment strategy & market, the next step would be to connect with an agent in said market to help find what you're looking for. As an agent myself, I can say a buyer that does their homework and brings a plan to the table is a much more motivating client to work with. In addition to helping you find and purchase your investment prop, a good agent will often have recommendations for local contractors, property managers, etc to help you with the rehab and managment of your property, should you need it. I'd recommend using the "Find an agent tool" on bigger pockets or reaching out via the forums to find an investment friendly agent in your desired market.
Hope that helps and if you have any other questions, my door is always open!
