Krista, you tend to make oddly committed decisions for someone that should be extremely non-committal. I haven't really jumped into the conversation thus far, but I was/am completely flummoxed by your decision to buy a house. Jebus, you were polling the GMTAN not even two months ago about where to live. When you're in that state of mind, you shouldn't even be making plans for next weekend let alone buying a house.
Just embrace the fact that you're currently a nomad, rent a place, and save the long-term decisions for when it actually makes sense to decide.
