Dual $300K income is achievable in households where they&#x27;re both engineering or management professionals.  But honestly, most of the people I know who&#x27;ve bought here have done so with the help of family money, eg. their parents plop down $500K for the down payment and they handle the mortgage.<p>Prices are also being driven up by a large number of foreign (largely Chinese) investment buyers.  Their incomes are driven by all the Americans who buy goods manufactured in China, and so normal salaries don&#x27;t apply.
