@dsimple You’re doing fantastic so far, congrats.
6 months’ emergency fund is “proper” for most people, but probably a little conservative given the job security of the military. Nevertheless, it’s a good thing to have, so, not suggesting you change that.
Yes, you should probably max your TSP before you open a brokerage account—retirement accounts are relatively untouchable, but compound interest is a fantastic thing.
Once you’re maxing TSP and IRA each year, if you want to open a brokerage account, I’d recommend using Vanguard and just contributing $X/month to VTSAX
If you want to be more aggressive, you can pick a few individual stocks instead of or in addition to VTSAX, but if you do, I’d recommend sticking to blue chip/buy-and-hold companies and not messing around with day trading, penny stocks, or crypto—just my personal opinion
If by “get into real estate” you mean investing in REITs to diversify your portfolio, then that’s fine, just do your research. If you meant housing, then look to buy the next time you PCS, but obviously pay very close attention to current rental rates and rental supply/competitiveness in that area, then factor in 10% on top as a property management fee once you leave, and see if the numbers make sense
Honestly, you don’t need to change too much at the moment - the slow, methodical, boring stuff like TSP, IRA, and brokerage contributions aren’t sexy, but they’ll set you up for a very nice life in 15, 25, 35+ years
