Moving from Chicago to the Treasure Valley, Idaho
The Midwest’s property taxes are quietly brutal — Idaho’s are among the lowest in the nation
The Chicago-to-Idaho Financial Case Is Stronger Than You Think
Chicago buyers are often surprised to learn how compelling the financial case for Idaho actually is. Illinois has a flat 4.95% income tax — similar to Idaho’s 5.3%, so the income tax difference is relatively minor. But Cook County’s property taxes tell a very different story. Effective property tax rates in the Chicago suburbs commonly run 2.0% to 2.5% of assessed value — some of the highest in the country. On a home assessed at $600,000, that means paying $12,000 to $15,000 per year in property taxes. The identical home in the Treasure Valley carries a bill around $3,000. That is $9,000 to $12,000 per year back in your pocket — a savings that compounds dramatically over a 20-year homeownership horizon.
Beyond the numbers, Illinois faces long-term fiscal uncertainty driven by significant pension obligations that create a risk of future tax increases. Idaho ranks 9th in the country for overall tax competitiveness and runs a balanced budget. For buyers thinking about 20-plus year homeownership, this is a meaningful consideration that makes Idaho’s stability particularly attractive.

Frequently Asked Questions
I love Chicago’s food and culture — will I miss it badly?
Honestly, Chicago has one of the genuinely great food and culture scenes in the world, and Boise will not match it in scale. What Boise does offer is excellent food for its size, a growing arts scene, Treefort Music Festival, and a lifestyle so oriented around the outdoors and community that most transplants find they were spending their Chicago entertainment budget on things they no longer need. Many Chicago expats describe Boise as having more of what they actually do — and less of what they pay for but rarely use.
How do the property taxes really compare in practice?
This is the most dramatic financial comparison in the Chicago-to-Idaho move. Cook County’s effective property tax rate is one of the highest in the nation. Idaho’s is among the lowest. On homes in the $500K to $800K range, the annual savings are typically $8,000 to $15,000. Over 20 years of homeownership, that is $160,000 to $300,000 — more than enough to fund substantial retirement contributions, college savings, or simply build wealth far more effectively.
What about Idaho winters compared to Chicago?
Completely different. Boise averages January lows around 23 degrees Fahrenheit with mostly clear, sunny days. There is no wind chill factor that turns a 15-degree day into an unbearable minus 25. Snow is moderate and manageable. Skiing is 16 miles from downtown. Most Chicago transplants describe Idaho winters as something they feared and came to genuinely love — especially after their first Bogus Basin ski day.
How hard is it to get direct flights from Boise to Chicago?
Direct flights between Boise and Chicago O’Hare run regularly and take about 3 hours. For visiting family or maintaining Midwest business relationships, the connection is very manageable. Many Chicago expats visit two to three times per year comfortably.
