Looking through all of this, I would get rid of the vehicle loans. While they aren't exactly killing you, it would free up some cash flow that you can immediately funnel back into your investment accounts (or into other areas to invest, pay down debt, etc.). I am soooooooooo over having a car payment, and after our last truck (purchased in 09 with a small loan), I swore that I wouldn't do it again, and I plan to keep that promise. The funny thing is, if I was tracking our net worth, about the time that it was paid off (12ish), is when things started trending upward at a higher clip.....this despite some bad "investments". I would be perfectly content to drive a beater the rest of my days, and I probably will. I would rather have the "cattle" instead of the "big hat".
I saw another poster said that if you pay cash for your vehicles, you think twice about the vehicle you are buying (and don't overspend as much). This is absolutely true as we are in the middle of this right now. We have an 02 Yukon (owned since 03) that is close to being on its last leg. To replace it with something 2-3 years old with low miles is probably going to cost somewhere around $45K-$50K. Mrs. GT (who is pretty darn frugal herself) has definitely had moment(s) of pause thinking about the thoughts of writing that check, and what that means to the total pot of gold.
Having said all of this, does anyone have a need for a slightly used HR guy?
