As @Eddie Silva mentioned we do get quite a bit of rain here, but not always huge amounts of rain (winter 16/17 was pretty bad though). The further east you go the more dry weather you get. I have no idea what type of work you're looking to do but if location doesn't matter a great place to get good weather, water, hiking, biking, etc is Hood River, OR. You might look into Bend, OR as well but it's growing and getting more expensive (nowhere near L.A. expensive though). they get more snow than Portland, but not a ton.
I live in the 'burbs west of Portland and while it's getting harder to find, there's still pretty decent deals on land outside of the Urban Growth Boundary. Look at areas like Sherwood and Newberg as well. I always tell people to visit the Portland area around November-January to get a feel of what it's like in the winter. It's a big change from L.A. but it's not that bad. The hardest part for me isn't the clouds or rain, it's the short days of winter. It's only lihgjt between 7:30am and 4:30pm at the shortest part. Lots of dark and even at noon the sun is only about 45 degrees above (if you can see it)
