Why do some people say a house “not an investment”?
I think the claim is that you shouldn't buy a house expecting it to increase in value as you would a stock portfolio. OTOH if you are looking at it from the stand point of "I need housing, mortgage payments and rent are comparable and I build equity if I buy a house rather then rent" that's potentiality a very different situation (that I'm not qualified to judge).
