Fire – How would you invest half a million for one year?

I’m planning to sell my house and after all is said and done I will make about $500K from the sale. I plan to buy again in a lower cost of living area, but first I want to take a year to move abroad and resolve some family matters.

Where can I best park the money for a year so that it builds interest without risk of losing the initial balance? Is a CD best for a situation like this? Or stocks? Others?

Since this is specifically earmarked for a new place to live I don’t want to return after a year and find my balance diminished; I’d just like to build interest while it sits. What would you all do?
