<p>Your estimate is fairly close. I looked up a random California Community College: De Anza in Cupertino. The resident per-unit fee is $17, and out-of-state students add $119 per unit for a total of $136 per unit. De Anza is on quarters, so three quarters with a typical 15-unit load would be 45 units X $136 per unit = $6,120 per year tuition alone. Living expenses including rent, food, expenses and books would be in addition to that.</p>
<p>The UCs OOS and the two private universities you mention would cost $45,000 to $55,000 per year.</p>
