In its U.S. Home Equity & Underwater Report, ATTOM reported that 41.1% of mortgaged U.S. residential properties were considered “equity-rich” in Q2’26, down from 47.4% in Q2’25. ATTOM defines “equity-rich” as a property with a loan-to-value (LTV) ratio of 50% or less. For comparison, just 3.2% of mortgaged U.S. residential properties were considered “seriously underwater” – defined as an LTV ratio of 125% or more – in Q2’26.
