What Is the Housing Affordability Index?

The Housing Affordability Index (HAI) is a key measure that shows whether the typical family earns enough income to qualify for a mortgage on a median-priced home. An index score of 100 means the median income exactly qualifies. Higher scores mean greater affordability; lower scores mean homes are less affordable.

The HAI considers:
• Median household income
• Median home price
• Mortgage interest rates
• Property taxes
• Insurance expenses

In Chester County markets like Exton, Phoenixville, and Malvern, the index varies due to neighborhood desirability, school districts, and local taxes.
