“We’ve owned our home (@5000SF/almost an acre with an ocean view/under $300K (edited typo of $400K) in La Jolla for almost twenty years.”

Can you provide more info on this? 19 years ago was 1989, which was near the peak of the previous bubble. In 1996 the lowest priced houses with ocen view in La Jolla were around $350K, for less than 1500sqft on less than a 1/4 acre. If they were down 30% from the previous peak (my estimate) then in 1989 they were around $500K. So how could anyone buy 5000 sqft on almost an acre in La Jolla with view for under $300K?
