Interesting... Any specific ETF you favor?I still owe 50% of the value on my house at 2.75% interest - I could pay it off tomorrow if I needed to, but why when over a reasonable time horizon I am getting back 7-15% on the funds.
I bought a house that the Gov pays me Living Quarters Allowance. I have roughly $2k mortgage, I'm paid 4k, roughly monthly. We had planned to cap our TSP or place the rest into principle, though your vanguard is worth considering.
