After doing a lot of research on Oregon, my family settled here in Corvallis. I would compare Corvallis to Sebastopol, CA, though I think Corvallis is a much more scenic place than Sebastopol is, and I loved Sebastopol.
It's not been raining so much this year as snowing. We woke up to a beautiful winter scene right out of Currier & Ives this a.m. My son got three snow days off this week. Everyone in the neighborhood has told me that this is very unusual weather for Corvallis, especially this time of year. Per the weather reports, we can look forward to snow and snow mixed with rain as the precip for the next several days. Glad I have some warm wooly clothing!
That being said, I agree with JAX111, you have to be able to handle the long stretches of cold, rainy, foggy days during the winter. The payback comes from the beautiful green hills and the flowers in the spring and summer and the bounty of crops at the farm markets. There's even a section in the local classified ads entitled "Good Things To Eat".
Both Albany and Corvallis have their plusses and minuses. The housing market is less expensive in Alabany - you get alot more home and property for your buck than you get in Corvallis. Here's a good local website for real estate info:
Willamette Valley Multiple Listing Service
Hope this info helps!
