I came across a great post analyzing condo prices in Pacific Heights at TheFrontSteps.com. Source of the article is a new blog Inside SF Real Estate, very much of the same philosophy as I believe in: independent analysis, hard fact, no bs. I’m adding them to my blogroll today.
They also have a great chart and article focusing on Noe Valley condo and home prices (wish I’d done it first 
). Go take a look. And good luck Arrian!
