<p>I was chatting with my son last night on one of my sisters that is sending one of her kids to college here. I think that college is about $40K. She’s also supporting another kid (lives near a school and goes part time and she’s funding his apartment (shared) and school costs (though I think that the college credit covers all costs). We figured that they are making about $180K/year in SF and paying about $40K/year for Federal and State taxes. They had help from her husband’s parents on their home and I’d guess that it’s paid off now. They typically drive old cars. If you figure about $60K for their living costs, that still leaves enough to pay full private costs which is probably about what they are paying for their two kids right now.</p>
