Congrats, Bryce! From a fellow active duty guy.
My magic number is $10K income a month or $150K capital gains a year post-tax, although I live very nicely on a lot less.
I spent 14.5 years training for my specialty straight through, and I'm consider R/E as you did. Already FI. Will be tough to say no to $600K/yr gigs, but if you know me, not really :)
I started with rentals (still have some) then went heavily into passive syndications. Leave it to the professionals. I get the same IRR without the headaches. Even recently doing a 1031 exchange and buying one rental is something I never want to spend time on again if I can help it.
Just refi'd out of my VA loan in Hawaii, may use a VA loan just one last time before I get out ;)
6 month goal is $9K/mo. in passive income.. or $75k/yr.. 5 year goal is Mandarin fluency, 30K passive vocabulary, being able to read novels and Classical Chinese.
I love my job now and I love RE, there is just too much else in live to experience.
