What the numbers say about San Clemente

The median home here, $1,398,400, is worth more than Orange County's $1,249,125 conforming loan limit. A cash-out refinance on a typical San Clemente home with a large mortgage can cross into jumbo territory, which is one more reason a HELOC that leaves your first mortgage alone often wins.
