If you want to get the absolute lowest price on real estate then wait until after the nuclear war with China/Russia/Pakistan/Iran (take your pick). I’ve got my lead suit ready and will drive my 4-wheeler out of its own spider hole and camp out in the best ruins in La Jolla. I should be able to get an excellent view of the crater from that vantage point.
You probably don’t even have to pay anything or even use a realtor!
