As home prices have surged in many places over the last five years, Illinois lagged the national average.

A new study by Boulder Home Source looked at all 50 states and analyzed five years of data from Zillow to determine where home prices rose the least. 

Illinois ranked sixth, as house prices rose 37.3% since 2018.

“The past five years has seen the housing market experience a lot of turbulence, leading to increases in house prices across America,” a spokesperson from Boulder Home Source said. “However, this study offers a fascinating insight into the states where prices are less likely to experience volatile increases and are more likely to remain relatively stable. This can serve as a useful guide to anyone looking to buy property in the next coming months or year.”

North Dakota topped the list with house prices rising only 22.7%, the lowest of all 50 states. It was followed by Louisiana and Alaska at 23.6% and 26.7%, respectively. Maryland and Mississippi rounded out the top five at 33.9% and 36.7%.

New York ranked No. 7 at 39.3%, Connecticut at 39.4% and West Virginia at 40%. Massachusetts rounded out the top 10 at 40.9%.
