I think people think of these types of questions as binary-that there is no overlap between an Escondido or Temecula buyer and a 4S buyer.
Sure, most people have an area they are interested in and stick to it. That said, if you can get the same house in Temecula as 4S for less than half the price, you will see people make that trade-off, which will pull buyers out of the desirable areas.
Nicer areas will hold up better, but the relative price difference can only go so high-prices in very different areas will, to a significant degree, move in tandem.
