In general, while average mortgage balances in states have climbed by 24% since 2020, median home prices have grown even faster. Some states saw median home value increases that were nearly triple that over five years.
Looking at mortgage balances first, the average mortgage balance has increased 24% nationwide since 2020, from $207,491 to $256,803 in 2025. Most states in the U.S. saw increases close to the national average.
But there are some outliers. Among the lower mortgage balance growth states are Connecticut, Illinois and Maryland. Each has seen balances grow the least since 2020 less than 15% (or less than a 3% annually over five years).
And the states where mortgage balances are climbing the most? If you've been following migration trends over the past few years, the names won't be surprising. Among the states where average mortgage balances grew by 30% or more are Arizona, Florida, Idaho, Montana, North Carolina, Tennessee, Texas and Washington state.
In some of these states, Chambers of Commerce are more than happy to tell you about their economic growth, which in part attracts new residents with jobs that allow them to purchase a home in their new state—to grossly oversimplify. That's certainly the case in Texas, where average mortgage balances grew by 34%, despite having a less tight residential real estate market than most. But other mortgage growth can be attributed to new residents driving up demand for existing housing supply, as is certainly the case in Idaho and Tennessee.
Among housing values, median home values have climbed as much as 66% in New Hampshire, according to Zillow. Other rustic flag bearers, Maine and Montana, also saw home values grow nearly as much. With apologies to their state economies, none of these states are undergoing an economic renaissance—it's more likely that the demand for vacation homes is increasing in these areas.
Median home prices have climbed sharply nearly everywhere, up 40% over the past five years nationwide.
