Also not accounting for a house being a place to live, raise a family, and store your stuff. Talking about it like it's just another investment is strange.
Not to derail the thread, but on the eve of my 30th birthday, if I've learned anything it's that "stuff" is a fucking liability, and spending a lot of resources on a place to house it is just one of the manifold reasons to perpetually avoid accumulating it if at all possible.
