[quote=spdrun]What’s wrong with “buy the cheapest house that suits your needs and when your wages go up, take some nice vacations, go for extra university courses, or spend it on the arts?”[/quote]

In many cases the needs grow as you grow. I remember sharing 1/1 with a roommate, no dishwasher and a sink that can hold 4 plates and enjoying it. Going on a trip from Bari to London with $50 in my pocket and no credit card. It is slightly less enjoyable with 3 kids in tow. In general kids change perspective. Especially if they are yours.
