In theory, you could do so now if you were in a bind with taxes and wanted to create a capital loss to detect from your taxes. I'm not sure how well that would work in practice though, since you don't see people selling houses for a fiat dollar anymore.
I would never trade in my whole house for just one Bitcoin because first of all I would never think that one Bitcoin is going to worth the same as a house.
That is just not a smart deal if you ask me.
I would have never sold the house at that price. Well, only if the price per Bitcoin will rise in a few dozen times. Or a toy house
