Dear Liz: We have two children in college, both entering their junior years. We have two more in high school. The two currently in college need additional financial assistance, as they’ve tapped out their federal student loans.

We are middle class, grossing about $125,000 a year, so we don’t qualify for much financial aid. We’re considering a cash-out refinancing of our home, but we feel as though we can do it only once, since each time we refinance it will cost us some fees, plus interest rates are likely to start edging up soon.

However, if we take out a big chunk of cash that could last us for the next two years for the first two children, and possibly some for the other two, we’re concerned that having that much cash sitting in the bank will reduce the amount of financial aid we receive, which would be counterproductive.

Is there a way to earmark the extra cash clearly for education expenses so that it doesn’t count negatively on our Free Application for Federal Student Aid (FAFSA)? Or do we just need to take this year’s cash out now, and refinance again each year (which seems crazy)?

As an aside, now that we have a little experience with this college thing, we will guide the two younger ones to community college or living at home while attending a less expensive public college, or something along those lines.

The first two just sort of went — without a lot of financial forethought.

Answer: The chunk of cash from such a refinance would be counted as a parental asset, provided the savings account is in your names and not those of your child.

So a maximum of 5.64% of the total would be included in any financial aid calculations. That’s not a big bite, but if you’re not getting much financial aid it could offset or erase the small amount you’re getting.

The bigger danger is that you’re taking on debt for something that won’t increase your own wealth or earning power. If you should suffer a severe-enough financial setback, such as a layoff, you could wind up losing your home.

In general, parents shouldn’t borrow more for their children’s college educations than they can afford to pay back before retirement — or within 10 years, whichever is less.

This rule of thumb assumes that you’re already saving adequately for retirement and will continue to do so while paying back the debt. If that’s not the case, you shouldn’t borrow at all.

If you’re going to borrow and can pay the money back quickly, a home equity line of credit may be a better option than a refinance. Interest rates on lines of credit aren’t fixed, but the costs are significantly less and you can withdraw money as needed.

Yet another option: parent PLUS loans, which currently offer a fixed rate of 6.84%. Approach these loans cautiously. It’s easy to borrow too much, since the program doesn’t consider your ability to repay. And like federal student loans, this debt typically can’t be erased in Bankruptcy Court.
