Definition
The Housing Affordability Index (HAI) is an indicator that determines the proportion of the population that can afford to buy the average home sold within a specific period. It includes various indices, with one of the most well-known being the National Association of REALTORS’ (NAR) index. The HAI is calculated by taking the ratio of a percentage of the average income of families in a particular area to the monthly loan payment required to purchase the average-priced home sold in that region.
An index value of 1.00 signifies that exactly half of the families in the area can afford to buy the average home, indicating that housing prices and income levels are in balance. A higher index value means that homes are more affordable, and a lower value suggests reduced affordability.
Examples
National Association of REALTORS (NAR) HAI:
- Average family income in the area: $60,000
- Average home price: $300,000
- Required monthly loan payment for the average home: $1,500
- HAI would be the ratio of the percentage of average family income to the monthly loan payment. Hence, if 0.25 of the family’s income covers the payment, the ratio for HAI is 0.25.
- Higher values of this index indicate increased housing affordability.
California’s HAI:
- Given the high property prices in regions like San Francisco, often results in a lower HAI, reflecting decreased affordability compared to the national level.
