Frequently Asked Questions
How much do Illinois residents save moving to Florida?

Is Miami a good alternative to Chicago?
Very different cities. Miami is expensive (comparable to Chicago), humid, touristy, beach-focused, and warm year-round. Chicago is cultural, walkable, lake-focused, and seasonal. However, Tampa, Orlando, and other Florida cities are much cheaper than Miami. For Chicago expats seeking warmth without Miami prices, Tampa or Orlando are better choices.
What's the weather difference between Chicago and Florida?
Chicago brutal: winters (snow, cold -10 to 30°F) and hot humid summers (85-90°F). Florida: warm winters (65-75°F, no snow) and hot humid summers (90°F+). For people escaping winters, Florida is perfect. For people loving seasons, Florida is monotonous. Florida's main advantage is no winter—no shoveling, no snow days, no seasonal depression.
