Zillow economists use an economic model known as the Zillow Market Heat Index to gauge the competitiveness of housing markets across the country. 

This model looks at key indicators—including home price changes, inventory levels, and days on market—to generate a score showing whether a market favors sellers or buyers. 

Higher scores point to hotter, seller-friendly metro housing markets.
