Portland, OR Long-term outlook?

[Shawn Moddes]

I've love to hear any opinions about the long-term (15-20 year) real estate appreciation prospects for Portland, OR.  

I'm not really an investor, but do own one single-family house in a great inner east-side neighborhood that was my primary residence - I now rent it out and receive some positive cash flow.  As I'm near the date when I'd lose the capital gains tax exemption, I need to either sell now or hold for the long-term. 

So, any general thoughts on what Portland, OR might look like in 20 years??  Thank you in advance!
