#1 -- Welcome to Lat G --- the BEST PT site...
#2 -- Glad you found this thread!
Sounds to me like you have your act together pretty good! So kudos to you.
I'm not a finanacial planner -- nor (I don't think) is anyone on here a professional investment advisor... this is just a good "Starter" thread that give people some stuff to discuss and think about.
Here's what I'd think about if I was in your shoes.
Max a ROTH IRA if you can....
If you have a FIXED RATE mortgage... and you'll be a reasonable age when it's paid off (some time before or at retirement) I wouldn't rush to pay it off. You're fixed rate mortgage will be mighty cheap 10 years from now... and if we're all lucky -- returns should far outstrip the interest rate on your loan. That's the "theory" anyway.
Now for that 401K at work.... It's not nearly as important how much you're putting in (and the match) as it is WHAT IT'S IN! Pay attention to that! You'll read here about Mutual Funds --- and you really need to have your money going into good ones -- because there's a 100 that SUCK and a very few that will get the job done for ya. So look into that.
Six months of savings is plenty in cash for rainy day fund.... so now it's time to start INVESTING... and keep reading this thread and you'll catch on real quick!!
