Homes are more affordable than they have ever been before. The housing affordability index is a number that shows the relationship between the average home price, average family income and the current interest rate. This index score is a great indicator of the overall health of the housing market. An index number of 100 is considered a good score and the current score is 205.9 which is higher than it has ever been before.
