One of the reasons is the affordable housing prices and stable cost of living structure.

First, the average housing price in Iowa is about $237,300, which is significantly lower than the national average of $416,100. This makes it relatively easy to purchase a home, creating an environment where middle-class families can afford to buy their own homes.

The rental market is also stable. The average monthly rent for a 2-bedroom apartment is around $900 to $1,200, which is quite affordable compared to major cities in the U.S.

In particular, the average housing price in the capital, Des Moines, is about $191,340, slightly lower than the state average, and the cost of living is reported to be 18.8% lower than the national average. As a result, Des Moines is often rated as one of the 'Top 10 Most Cost-Effective Cities in America.'

Iowa is considered one of the states with a low cost of living in the U.S. The cost of living index is 83.7, which is much lower than the national average (100). Grocery prices are also about 8% lower than the national average, and being an agriculture-centered state, there is an abundance of fresh produce available locally, making grocery expenses manageable. Especially, corn, soybeans, meat, and dairy products are supplied locally, ensuring high quality at reasonable prices.

The tax structure is also relatively less burdensome. The income tax rate ranges from 4.4% to 6%, which is below average compared to other states. Property taxes are at the national average level, but since housing prices are low, the actual tax burden is significantly alleviated. Additionally, the sales tax rate is an average of 6%, which is also considered low nationwide. Thanks to this tax structure, Iowa residents have a greater disposable income relative to their earnings, making saving and asset accumulation relatively easier.

Healthcare costs are also somewhat lower than the national average. Iowa has well-developed local hospitals and community clinics, allowing residents to receive care at reasonable costs compared to large cities. The accessibility of healthcare services creates a less burdensome environment for the elderly and families.

The education level is also high. Iowa has a strong public school system and many affordable state universities and community colleges. In particular, the University of Iowa and Iowa State University are highly regarded nationally, allowing residents to receive high-quality education at lower in-state tuition rates.
