Since none of the communities being discussed even existed when we purchased in RSF, it has been interesting to visit all of them with friends who are looking in the area.
There are definitely pros and cons to each area, but our friends have mentioned they don’t want anything east of I-15– for various reasons–no matter how great the house is.
As far as the OP is concerned, IMO, as long as you can actually “afford” the house–whether prices go up or down–you’ll enjoy the area, regardless of where you buy.
My wife and I were raised in LJ, and,–although we’ve lived all over the world–we feel San Diego is one of the finest places on earth.
