As already replied, be sure to continue to fund your 401(k). Is your spouse contributing to some retirement account like an IRA. How much of what you are contributing to your 401(k) will be going to purchase the new house.
Since your other interests are college for children and buying a second home, as well as retirement and travel. I would ask some friends in the area who they are using for a good financial adviser. A good financial planner should utilize a total approach. Looking at cash flow, investments, wills, trusts, insurance both life and disability, as well as your college plans whether you use educational investments or 529's. I live in Charlotte and use James Allison with Met Life. You can see his website at
