Miami is actually halfway acceptable because it’s heavily non-American and multicultural. Not to mention having some very cool architecture.
What about downsizing and just lowering your expectations? Condo of about 1000 sf with outdoor parking. Who needs a gar(b)age in California weather, especially if you drive a used car or two that you don’t care about a few scratches on?
I don’t see a huge shortage of the above in beach cities for $400-500k.
