I agree with your Texas veteran approach to college for your kids. It’s one of the reasons that our daughter switched her residency from Hawaii to Texas this year.
Here’s more thoughts, and I apologize if I’m preaching to the choir.
If you both make it to retirement eligibility then all of your savings will only have to bridge the years between his active-duty pension and your Reserve pension. It’s quite possible that by the time you’re 60 years old, your two pensions will exceed your spending. Every dual-military couple I know has this “issue”, so when you’re straightening out your real estate make sure that you also have a landlord exit strategy.
When you both get pensions, you need to decide whether you want each other’s SBP. My spouse and I elected not to take out SBP on each other because we’d rather have the 6.5% now to spend on each other. If one of us dies now, the survivor has more than enough assets to do just fine without SBP. If you’re concerned about the safety margin, another option would be to take out term life policies on each other to expire at age 60 (when your pension starts) or age 70 (when you’ll be taking Social Security). That’s generally cheaper than 30 years of SBP premiums.
Your SBP decision may also have to take your kids into account, especially if they have special needs with an insurable interest in SBP.
For the last 11 years I’ve been leisurely converting our two conventional IRAs and two TSPs to Roth IRAs, and not worrying too much about skipping a year when our income goes over the 15% bracket. This year I realized that our income (and my spouse’s Reserve pension) when she reaches age 60 could push us right through the 25% tax bracket into the 28% bracket. In addition to that, our accounts have experienced considerable growth during that time. I only have eight years left to finish these conversions, and now I’m not worried about straying up into the 25% tax bracket to get it done.
