Buying power works in your favour here: Iowa's cost of living is roughly 10% below the U.S. average (index 90.3 vs 100), so that $75,380 take-home stretches further than it would in a pricier state.
What $75,380 Take-Home Really Means in Iowa

Landlords often look for rent no higher than 30% of take-home, which on this income is about $1,885 a month. Adjusted for Iowa’s cost of living, your $75,380 take-home has the buying power of roughly $83,477 at national-average prices — a bit more, since Iowa is cheaper than average.
For context, a $100,000 salary is about 137% of Iowa’s median household income of roughly $73,100 — well above the typical Iowa household, though that median often reflects more than one earner.
