Why do some people say a house “not an investment”?
A house is a funny kind of investment. Normally when you invest, you do it to make money. The return on a house, though, isn't principally real money, it's the imputed rent - money that you would have needed to pay to rent the house. The thing about this imputed rent is that you consume it right away. Getting a bigger house and putting more money into it doesn't save you any money, it's just a way to consume more "house" - so, unlike regular investing, it's not really responsible and doesn't contribute to your financial well-being.
