It really depends on what your priority is. Is it land or is it home? Is it coastal (within 5-10 miles) or not? How about Mello Roos or HOA fees? Does age of the home matter to you?
There are really some substantial variables that you can help us with so that we can make recommendations that are more pertinent to your needs.
For instance, the Olivenhain area that sdrealtor mentioned is definitely one of my personal favorites. The entire area kind of back around the Lone Jack area is very very cool and it may match what you are looking for. Lots of homes back there on large lots and they are not cookie cutter types. The prices out there have been REALLy sticky though and I think this area will continue to be sticky. Lots of heavy equity and established homeowners out there. I eyeball it alot for myself but am simply way priced out of there. Nothing really decent there under 1.2 right now at the bare minimum. Again though I would agree with sdr that it is one of the best hidden gems in the county.
Also please don’t confuse sticky with immune. Alot of people here hear the words sticky and they confuse that with immune.
There are alot of other areas as well. Again though I am a bit hesitant to just fire them off because for all I know they will not really match what you want. Does commute matter to you at all, and if so where do you commnute to? Again, if you could throw in some more personal preferences as I mentioned above we could help refine our recommendations.
