> without temperature extremes in summer or winter
That's going to limit your options tremendously (in the US at least). Parts of Southern California would fit, if desert is an acceptable type of nature for you. The cities are expensive, but smaller towns aren't always.
What are "extremes" for you, anyway? Are hot summers OK, but cold winters are not? Vice versa?
The only place I have personally been with lots of nature and mild weather year-round is Guatemala. Perhaps somewhere in the Mediterranean region?
