Since we bought our new house, we've had to confront the possibility that we've already lost money.  Over at our sister publication, I explore why that doesn't bother us:

Although I may spend odd moments cruising through the listings to see what neighboring houses have sold for, my husband and I agree on one thing: "Who cares? We're not going to sell," he said the last time I told him about a comparable house that sold for less than ours.

We didn't buy our house for an investment; that's what our investments are for. Our house is to live in. We bought mostly because we wanted to commit to a place, and to make it over to suit us exactly. Landlords get testy when you rip out walls and replace the stove; besides, who wants to spend money installing custom blackout curtains only to have the place sold out from under you?
