Hey Kyle!
This is key in determining markets you want to invest in, their are a few different strategies I would recommend to get the best info!
-Local real estate agents, finding a realtor you can trust in some markets you are interested in is key. They often provide great insight on what neighborhoods are desirable and where investors are buying. Just be sure you find an agent who isn't just trying to push you for the commission.
-Property management companies, you can contact property managers in the area and they can provide insight on where their clients are buying, rents, neighborhood details, crime, etc.
-Other investors, connecting with other investors in different areas is the best option, you get to meet like minded, successful individuals doing what you want to do. The best info will be from the people who are "doing" it actively. Active buyers, in specific markets etc.
These are my 3 top ways in which I break down new markets.
Hope this helps, best of luck
