Phoenix Quick Reference
Wisconsin sends a large share of its retirees to Phoenix — the I-90 corridor from Milwaukee to Phoenix is a well-traveled retirement route. The Sun City corridor has a visible Wisconsin presence, and the cultural fit is natural: Wisconsin's Midwestern values align with Sun City's organized, activity-focused culture. Golf culture in Wisconsin runs deep — the transition to Sun City's 11-course RCSC network resonates strongly.
The property tax improvement is the most immediately felt financial change for Wisconsin retirees. Waukesha County homeowners paying $7,000–$9,000/year in Wisconsin property taxes who move to Sun City West find themselves paying $2,800–$3,800/year. The annual savings of $3,000–$5,000 are tangible and immediate — showing up in the first full year of Arizona homeownership.
The Financial Picture
Wisconsin income tax: 3.54–7.65% graduated. Arizona: 2.5% flat. Annual savings on $80K retirement income: $840–$4,120/year depending on bracket. Wisconsin does not tax Social Security above age 65 for most filers — so the SS exemption advantage over Minnesota doesn't apply here. The property tax and lifestyle cost story drives most Wisconsin moves.
Milwaukee County effective property tax rates: 2.0–2.8% of assessed value. Waukesha County: 1.5–2.0%. On a $350,000 Wisconsin home: $5,250–$9,800/year. Phoenix comparison: $2,500–$4,500/year. Annual savings: $2,500–$5,000 — meaningful over a 20-year retirement.

Waukesha County (Brookfield, Pewaukee, New Berlin) and north shore Milwaukee suburbs have appreciated well. Most Wisconsin retirees have equity sufficient to fund Sun City or Sun City West purchases outright. The equity story is solid if not dramatic.
Wisconsin spring market is short. The fly-and-visit pattern in January–February is well-established — Wisconsin retirees experience Phoenix's perfect winter weather and return home to -10°F wind chills with the move locked in mentally.
