[quote=bearishgurl]AN, it’s late and I will call it a DAY (for me, anyway). 4S is NOT part of RB…[/quote]
Hmm… SDLookup is not agreeing with you: Here’s the link: http://www.sdlookup.com/Real_Estate-Rancho_Bernardo-Houses_For_Sale-92127. Please tell me what you see that the title of the area covered by 92127?

[quote=bearishgurl]An “exurb” is a far-flung area (established or not established) which is situated far from job centers, whose residents are largely freeway dependent. It often does not have all the retail and other services locally within it which its residents need. In addition, it is served very minimally, if at all, by public transportation.

Hope this clears your confusion.[/quote]
By this definition, 4S must not be an exurb, since it’s quite close (5-15 minute drive) to several large corporations. What retail and services do you think one need that 4S does not have? So, no, it hasn’t cleared up much confusion. Unless what you’re say is, you’re wrong with this statement:
[quote=bearishgurl]In the SD County “exurbs”, the vast majority of =<3000 sf SFR's are built on substandard lots (<5000 sf), are encumbered with an HOA and also usually CFD(s). The vast majority of 30+ yr old houses in SD County sit on bigger lots and have far more desirable locations than those built in the "exurbs" in the last 15 years.[/quote]
So, Bonsall, Fallbrook, Ramona, Alpine, etc. are true exurb. With this list of exurb, do you think the above statement is true?
