@Tyler Braithwaite Congrats on taking the first step! I would try to absorb as much free content as you can to determine how you want to acquire the rental property. Are you just going to put 20% down and buy one that's rent ready? Are you going to do a BRRRR? These are two different ways to purchase a rental, but would need two completely different paths. One requires saving much more money, the other requires renovation knowledge and a strong network.
Once you know exactly how you want to buy the rental, it will be much easier to lay out your next steps. If you're looking for a book though, I recommend starting with How To Win Friends & Influence People by Dale Carnegie. Not a real estate book specifically, but a great book that will certainly help your real estate investing and your networking.
So that's my opinion - absorb a ton of free content, read that book, save as much money as you can in the meantime, and network your butt off!
Best of luck!
