Growing mortgage rates are having a major impact on home sales, and in some metros, increased mortgage rates have made it especially hard on buyers. The average mortgage interest rate has stayed above 6% on 30-year fixed mortgages during 2026, according to a recent report from WalletHub. The report looks at mortgage rate increases from Q-1 to Q-2 2026 and found that mortgage rates grew in 37 states.

In which states did mortgage rates grow the most?

The states that saw the highest mortgage rate hikes from Q-1 to Q-2 2026 are Mississippi, Colorado, and Tennessee. Mississippi ranked the highest at 1.9% quarter-over-quarter, followed by Colorado and Tennessee, both at 1.6%.

However, these states don’t necessarily have the highest mortgage rates. As of Q-2 2026, Mississippi’s average mortgage rate sat at just 5.5%. Meanwhile, the average mortgage rate in New Jersey reached 6.98%, and in Connecticut, it was 6.61%. New Hampshire also had a high average mortgage rate at 6.53%.

Other states saw mortgage rates decline

While most states saw an increase in mortgage rates, a few states saw rates actually decline. North and South Dakota saw the sharpest quarter-over-quarter declines, falling 3.68% and 1.22%, respectively.
