When looking at the ZIP codes with the highest mortgage balances in the country, it's no surprise that California ranks in the top multiple times. Of the top 25 ZIP codes with the highest mortgage balances, California is home to 17 of them. The other eight are split between New York and Connecticut.

Home values in these areas are known to be some of the highest in the nation. And compared with the average price of a new home—which, according to the U.S. Census Bureau, was $377,200 in May 2019—each of these top areas have home values that are significantly higher than average.

Incomes in these ZIP codes are also consistently higher than the national average, according to Experian data. The lowest estimated income among these top areas was $108,612 in the first quarter (Q1) of 2019—more than $25,000 higher than the national average of $79,622.

For this article, Experian reviewed consumer credit data from Q1 2019 to identify the top ZIP codes with the highest mortgage balances.
