Like you, I'm curious about 1212 Parkinson too. It got multiple offers in the $2.1M+ range last December and it ultimately sold for $1.76M in August. So I'm trying to figure which one of the following two things happened:
(a) either the Palo Alto market for SFR homes in the $2M range has actually softened by that much since last December -- which is scary, or
(b) it was a situation unique to that particular house and to that particular seller's sales & marketing plan.
