Oregon and WA are too piglets out of the same litter. Oregon being a bit more liberal/communist. Any property along I 5 is 10X as expensive and 100X more liberal than anywhere else in the state (except maybe beach front)
Oregon has no sales tax, but has a high income tax. WA has no income tax, but a high sales tax.
I have never done business in Oregon, so I do not know their state business tax structure. In WA something like a bakery would have a B&O tax rate of 1% of the gross. If you had a consulting business the B&O rate is 2% of the gross. The basic dividing line is: "Are you "manufacturing" something or are you selling items manufactured by someone else...(1%) or not (2%)
To be more specific, you will have to see whether you need to be close to a metro area, or if you are flexable and can live quite a distance from I 5.
Where I used to live on the west side (wet side) of the Cascade Mountains (2 miles for I 5) land was about 100K an acre. (we sold 2.5 acres for $250,000 6 years ago) If you backed away from the Freeway a 50 miles or so you could find land for $10,000 an acre.
If you get over here to the dry side there is land available from $250 an acre and up. 15 or 20 acres with water (no buildings) start about $50,000. A really nice 80 acre piece (with water) went for $113,000 recently. As you already probably know from living in Nevada, water is everything over here. If you have no water, that is where your really cheap land is.
However, the population concentration is on the wet side for your bakery business. Or maybe Spokane, Wenatchee, Yakama, the tri-Cities, or Pullman. East of the Cascades (the dry side) is less expensive, dryer and more concerned with water, hotter in summer, and colder in winter. West of the Cascades (the wet side) is more expensive, more concerned with drainage, and has a milder but wetter climate.
These same conditions continue down into Oregon. A larger town in Eastern Oregon that might be big enough for a high end bakery would be Bend. I have lived in both states, on the coast, in the I 5 corridor, and now we live on the dry side in North Central WA. (follow US 97 down from Canada, you will pass within 5 miles of where we live). I like it here.
