I agree that buyers are optimistic but check any of the big tracts in that area like Summerfield, Fieldstone, Village Park, Cantebria, Sandelwood, Cambria/Mendocino, Encinitas Ranch, Villanitas, Rancho Ponderosa, Arroyo Vista, Santa Fe Trails, La Costa Oaks, La Costa off Levante, Greystone on the park etc (did I miss any?) and you will see prices down about 5%.
The only transactions that were 5 to 10% higher were a couple cases of apparent lender fraud by a single agent (Super Janae).
