Just 40 minutes away, and beautiful views all along the drive.
Many of the rural properties have a septic system & well,
so budget for that kind of testing. Stevenson is a charming little town
with some good summer events. Knowing which side of Portland will be your main commute target can make a big difference in this decision. If you'll be working in Beaverton/WA County, consider a property 1/2 wy to the Oregon Coast, or toward the Columbia River. Veronia is a nice little town, with a Friendship Festival in early August.
Possible site in Wine Country communities too, west of Portland...like Newberg or Sherwood, but traffic can be an issue. Beautiful country, here, so if you enjoy that aspect of driving, parhaps choose a country road commute, rather than a freeway? Can you work part-time from a home office?
We have lots of excellent Brokers here who can help you find a place that fits your whole list.
Often a larger property will offer Rental or Lease possibilities to allow you to make a higher offer.
(I'm pretty familiar with the market right now and have seen some great ones recently. Can act as a Finder for you if you, and do research on the properties if prefer to look without a Broker - until you are ready to negotiate & write your Offers. Zillow.com can help you assess some info from Public Records, as can http://www.PortlandMaps.com Trulia's map search function is a good place to start, using the town names I suggested above. Have fun with it - and Good Luck!
