My 2 cents
I would not say that a bubble/bust would not occur again in SD, but I don’t see enough new homes going up currently to match household formation so IMO we are likely to remain in a housing squeeze for a few more years at least (maybe 5).
Also your savings purchasing power is likely to be eaten away by inflation over that period as well.
Bottom line:
We may have another housing bust someday but it is very (VERY) unlikely to come anywhere close to the bust in 2009-11.
If you can find something (even in Temecula etc…) buy it.
The above assumes the whole world economy does not get sucked into a black hole in the next few years.
