@Brandon Reynolds I hear you. You think big, follow the rules, and find you've achieved your goals either as planned, or in your case, ahead of schedule. What I would suggest from my vantage point of reasonably the same level of financial security (proportionate to being a little older) is to stay the course. Here's a few quick tips that I would offer specific to your situation (of course, as @Account Closed said this is an internet forum and we are strangers so take it with a grain of salt!).
1. Stay the course with your financial plan. You are starting off well with your retirement and your wife's retirement. Consider continuing this savings plan rather than stopping. Your wife should be able to contribute to a Roth IRA or a normal IRA or some form of retirement, you should be in a position to continue to do the same. Sounds like you are contributing to a college fund, suggest continuing in this regard. The downside of retirement is you're transferring control to other people to manage your money who invest in other companies whose managers are sometimes idiots. But for the most part, it becomes a savings account you can count on in the long term. Strongly dissuade stopping what has worked well to give you financial stability (retirement, good debt to income, liquidity) - and the banks would probably see it the same way.
2. Buy a house and manage the project. It clearly sounds like you have the balance sheet to take on a moderate single family home project. Because you have a good financial footing you can probably qualify for a 20% down, 100% rehab loan from a local community bank or credit union (or one of the bigger banks but they can be more difficult and time consuming to deal with). Use your expertise to choose an area where you can buy a fixer upper either as a flip or rental property. Spend some time driving the blocks and really try and pinpoint your area. Then find out the realtors that are selling the distressed, run down, rehab needed homes and let them know you are a buyer. Develop a relationship with a bank so you know they are on your side once the realtor finds you a deal. (Here is a thread I posted on how to find properties.)
3. Manage the project. Take your time, plan it out, involve your spouse as much as they are interested, and do what you do best. Some people will tell you to run the business - i.e. hire other people to do the work and manage them - others prefer to be the workers. Up to you whichever you prefer, maybe try one the first time and a different approach the next time. From your brief self description sounds like you might want to take this one on yourself.
4. Don't forget about the spouse & kids. Know what you need to give your family before you start giving your time away to this new project. A banker I am networking with to try and understand what is needed to finance larger projects (you would think it's the cure to cancer, irradiating smallpox, and alleviating poverty...) recently wrote this quote and I am sharing it with you as much as it's probably helpful self-reflection for any BP members, "many [entrepreneurs] rarely get a chance to spend time in that house because they are so caught up in being entrepreneurs."
5. Work as a team. Finally, spend time developing your team. Even if you only do one deal every year or so you want to align yourself with a good realtor, contractors and subs, a good title company, and a bank that can service your real estate investment needs. Whether you end up doing all the work yourself or managing others, keeping a "team" perspective is important to get through the tough times that will surely come; and it will also help alleviate your early onset of midlife crisis.
In any case... you're in an enviable position! Good luck and enjoy!
