Del Mar real estate sales for single family homes took a major hit from '04 to '05 with a 35.5% drop in sales. A spin doctor would take that information and run to her local media source to try to get an article published because that's sensational news! However, if you look at the same year but a different statistic, you would see that the average and median single family home sales price in Del Mar enjoyed a 13.3% and 17.2% increase respectively over the same period of time.
