Aside from the early withdrawal option, you may be able to take a 401k loan from your account. You need to check with your plan administrator to see if your plan allows the loan option. With the loan, you may be able to switch part of your loan to a lower interest rate. Plus it may be a better use of your money because there is no tax or penalty. Since the 401k has $67,000, the maximum you can borrow is $33,500.
The thing you may need to consider is that the loan term is only 5 years, so you will probably need to make higher payment on your loan. Also, keep in mind that the loan option is only available to your current 401k. So if you leave the job, the loan may become due in full.
All in all, either borrowing or withdrawing from your 401k is not recommended, but depending on your situation, it may work. Consider all the factors before making your decision.
