Hi S - Forest Grove has some great properties available right now, and it sounds like a great community to live in, but if you are commuting far, don't be fooled by the distance on the map. Commuting into downtown IS easy by train, but it's still about an hour train ride from the Beaverton transit center. (If you take the train in Chicago, this might seem like nothing to you?) Travel on Hwy 26 is often a bearcat, getting in traffic jams even on the weekends.
I held an open house in Forest Grove a few weeks ago for one of my team leader's listings and this house is great. It had the most gorgeous pine (?) floors, great room, huge granite island and a huge property around it. http://www.mlsfinder.com/or_rmls/tedimcknight/index.cfm?acti
Sherwood is another growing suburb (recently listed in the Best Cities to live list- Forbes?). It does not have access to a light rail train system yet, but they are working on getting the traffic situation settled because it has seen such growth over the past couple years. It's a great town with a small town feel and nice people and decent home prices - there are a lot of new communities with cute townhomes and single family homes. They also have a nice city center with a new library, new restaurants etc and the Oregon wine country starts just south of there.
Please let me know if you need any other information, I'm here to help!
