San Diego advantage: California Prop 19 basis transfer saves $5,000–$15,000/year on property tax for California downsizers. Phoenix has no equivalent.
For Bay Area/LA retirees moving south, Prop 19 cuts San Diego's cost advantage of Phoenix roughly in half.
Example: With Prop 19, San Diego annual carrying cost drops from $35K to $25K (still more than Phoenix's $17K, but much closer).
