Costs in general are climbing across the country, and mortgages are often already a significant chunk of people’s monthly budgets.

According to Experian, there are 67 cities where the average mortgage is $1 million or more, up from 47 in 2024 and 23 in 2023. Out of the top 50 of those 67, California dominates, taking up almost half of the spots on the list. Florida also shows up high on the list, making up the top five, though in total there are fewer than 10 Florida locations in the top 50.

Even though some of these “cities” are small towns, villages or private communities, Experian counts them all as cities in its data. Here are the the top 50 cities with the highest mortgage balances in 2025.
