@Noah Joseph Armstrong Financially free next year at 23 years old? You're still going to work, right? Don't fall for the FIRE myth that it's time to sit on a beach for the rest of your days. As a motivated & productive member of society, you've been working hard for a long time and you'll still need to keep doing something productive. Hopefully that will at least be your real estate investing...
Regarding 0 down....forget it. Been there, done that. Lost my shirt. 0 Down = stupid overleveraged = incredible risk exposure. Especially in this highly-valued market. It sounds super sexy, and honestly when I did it decades ago at about the same age as you, I got a major rush doing the deals. But after that, things went down hill fast with what turned out to be negative cash flows.
Sounds like your house hack is working very well, nice work! I would embrace that for now and keep building your war chest. Not sure I personally would want to buy a long distance rental. Maybe you bump up your schedule on moving down south so you can start investing local to you sooner, especially if you know you want to live down there anyway.
Good luck to you,
Dave
