Ok, glad there are some people with Oregon experience! Here are answers to some of your questions.
1) The house. It's in the Collins View / Palatine Hill are north of the Tyron Creek State Park and west of Lewis and Clark College. It's about 1000 ft northwest of the intersection of Terwilliger and Boone's Ferry.
2) Why buy now? Interest rates have been at historic lows, and we plan on living in the house for 10 years or more. We currently rent, and it's horrible, but we don't have to sell a house to buy one. In a declining market, the buyer has pretty incredible negotiating power. I just got a new job in Lake Oswego, and I'd really like to be closer to work.
Since we're planning on holding the property for at least 10 years (if not more), it's more important for us to get a lower interest rate rather than a lower price. For example, if the market prices fall 25% but interest rates go up by 1% (i.e. 5.5% to 6.5%), the end result over the course of a 30-year loan is the same.
Thanks for all the good advice. I think we will start the ball rolling with another lender just to have a backup plan. Thanks!
Here's something interesting for you Portland folks as well. Based on the latest case-schiller data, here's a fun graph I made:
