Hi there Garett!
Welcome to BP and this crazy world of investing!
Thank you so much for sharing your story, I love hearing how other investors got there start! I began my career in real estate a year ago by getting my license and acquiring my first house hack! It has been a whirlwind since then and I love having the opportunity to share what I've learned through my experiences.
You are a smart to consider Tennessee (particularly Middle i.e. Nashville). It's market is extremely active and will remain so for a little while longer; the solidity is grounded in geographic location, climate, diverse employment base (ever expanding), higher education, no state sales tax, hospitality/tourism, music and entertainment, the list goes on and on.
I remember a BP episode from last year I believe about long distance investing and how important it is to establish your 'core 4' (think boots on the ground i.e. Realtor, Lender, PM, Contractor) in whatever city you've chosen to buy in. I'm pretty sure it was the David Greene episode because he has a book called 'Introducing: Long Distance Real Estate Investing'. So to answer your question about how you find good properties, I would say you start by finding the good people, who you trust to be your boots on the ground.
If you're in need of a mortgager or just want a second opinion to get a better rate from your guy I highly suggest talking with Kyle Deutschmann. Working for one of the top-rated lenders on Lending Tree, he is also an avid BP listener so he is able to comprehensively understand your wants and needs during the process.
If you're in the area, let's grab coffee! If not I'd love to answer any questions you may have as well as get to know more about what you're goals are! Funnily enough, I also want 2 more rentals by the end of the year! Let's make it happen!
