Purchasing Land

I'm considering moving from my city (Portland, OR) to the countryside. I need to remain within ~30-60 minutes of the city. Here are a few things I'm interested in for the new property:

• I'd like it to have running water (i.e a stream with associated water rights), as I think that it would be nice to find wildlife in it, play with small-scale hydropower and for the general beauty.
• I'd like for it to have a variety of terrain. Flats and inclines.
• I'd prefer a variety of biomes (woods, fields, mountains).
• I don't want to carry a mortgage on the new place.
• The land needs to be adequately sized for a moderate garden.
• There needs to be space for additional structures (definitely a workshop, but also perhaps a small, standalone home office deeper in the woods?)
• It should get good sun in order to use solar power.
• It needs to rain there for passive water sequestration purposes (i.e. not in the rain shadow).
• It needs to be grid connected, including high speed internet. While I endeavor to reduce our grid reliance, I work from home, so this is a must.

I'm flexible on some of these, especially the mortgage one, but this is the general thrust of my interest.
