I would say 453K for 3586 s.f. in the Northern part of Temecula is 2003 pricing based on my recollection. I will try to find some examples and #’s to give a more accurate answer.
I like using sales of the same model home over time to measure price changes. The median price in a zip code can be VERY misleading due to differences in house sizes and different neighborhoods selling at different prices based on their amenities, etc. You have to compare apples to apples to know what is truly going on.
