I hope my posts bore you enough to add Rancho Santa Fe (92067) and Santa Luz (92127) to your analysis.
Santa Luz and Del Sur are included with 4S Ranch and Rancho Bernardo.
I don’t have enough resale data for 92067 to get reasonable accuracy.
Sorry if you already answered this question, but: Do you exclude the first sale of any given property?
No. In fact my data won’t even tell me if a sale is the first sale or not. But a house must sell at least twice between 1999 and today to affect the index.
