I've follow Robuilt, sean razditch & the real estate robinsons on youtube. Great content. Robuilt is more for "overall STR" advice. Sean is deep in the weeds when you already have one.
I would suggest joining some facebook groups for STR hosts. A word of warning though, the only posts you will see are usually horrific problems. It may sour your taste for buying a rental. Realize though that many of these groups have tens of thousands of members who are not posting their highs, only their lows or where they are looking for help. But... it's a good indicator to see if that scares you away.
Find out what really scares you or where your barrier is, then learn everything you can about that. With a STR, there's a lot to learn.
How do you list your property, what software do you use, what pricing strategy do you use, where should you buy, what kind of furniture do you use, sheets, towels, how do you find a cleaner, how do you manage your cleaner, who will you use for hvac, handyman, plumbing, pool maintenance etc. How do you track expenses, manage taxes. The list goes on...
It's really easy to get lost in the details but they all can be handled individually and over time.
Understand that it's a long term game. You will make mistakes your first year but they get less as you get more experience. Your first rental is the hardest, then it gets easier...
