Day 23: In 1900, the average household had paid 10 times its family income for a house, and by the 1930s (during the Depression) it was up to over 18 times the family income. And despite the fact that most of us feel housing prices are skyrocketing, the average household only pays about 4 times the family income for a house now. **
Well, I think there are other things not taken into consideration with this statistic - most families in those days only had one income, not two - so I think you could feasibly say we are paying about 7 times a family income.
