Thanks everyone for your comments - let me answer some of these questions:
No 529 set up. Not sure what to do with this just yet. Need to figure out retirement savings first.
2k a month is before taxes.
The current mortgage is a fixed rate 30 year at 5.25%. Some of you asked why not refi now, and the reason is that I'm assuming to make it worthwhile I need to own 80% and get rid of PMI, which we are currently paying. We have refinanced once already and when I tried to refi again the lender we originally went with said we couldn't unless we owned 80% - can't remember but has something to do with the type of loan with have. Fannie Mae? Freddie Mac? Freakin Frack? (will have to get it out of the files to find out what we have)
Golfer44 - thanks for the tip on keeping the pay down $ more readily available - good food for thought.
We do have an emergency fund here are the details I left out regarding other savings:
Emergency fund in Capital One 360: $6000
Vanguard REIT non-retirement account: $11,000
Roth (for me) currently being transferred to Vanguard from Valic: $5000
Valic IRA (from prev. job): $13,000
TIAA-cref IRA (from wife's prev. job): $8000
SEP-IRA in Vanguard (just started): $1500
We love the house and plan on staying at least until kids graduate high school (15 years or so) - I wouldn't mind keeping it if we move as a rental property, so owning outright someday sounds like a good plan. Moving would entail moving farther away from work (we live in the city) in order to move into a less expensive house. This would mean new schools, longer commute, and a major major change we're not really feeling up to. We love the city and love our community.
I have seriously considered moving the 140k to Vanguard from Amer. funds - but it's been doing so well there I've been hesitant so far.
So back to my original question of having this 2k extra each month (let's just call it 2k after taxes) - I'm hearing differing thoughts on prioritizing - 1. get out of PMI which means I need to save up 50k and refi and 2. max out retirement fund.
Any other thoughts on why it would be a bad idea to put 100% of the 2k each month toward a savings account meant to accrue 50k, then refi and get rid of PMI, THEN start socking away into retirement funds? I realize there could be an infinite number of distributions of what to do with the 2k, and that's exactly why I'm posting - just curious to hear thoughts on ways to distribute.
Thank you all again for your suggestions -
