I have lost the train of logic in the last page or so…yes I have been lurking.
I would like to clear something up apart from the flipping debate, When people say housing in certain neighborhoods of SD are a good deal or affordable, I want to vomit. There are no neighborhoods in SD where the median income can afford to buy the median home (3X annual income rule). The only way people can afford homes in this state is with preexisting equity, artificially low interest rates, and/or crazy mortgages.
If you are curious, the ratio (income to home value, historically <3) is generally between 7-11 for most san diego zip codes. So if you want to say homes are a good deal, or affordable or whatever, you have got to get out of the state and look around.
Logically, I would say this is unsustainable, but home prices have been pretty crazy for the last 20 or so years.
