Let me count the ways. First, you will lose any investment gains or compounding interest on the amount borrowed, which you can never make up. Second, if you get laid off or leave your employer for a great opportunity elsewhere, the loan on your 401(k) would come due immediately. That means you must replace the money right away or, unless you are 55 or older, pay taxes on the amount you took out plus a 10 percent penalty for the privilege of an early withdrawal. So, the $6,700 you borrowed will wind up costing you about $9,000. Third, paying the balance of your school loan won't improve your credit score as much or as quickly as you might think.
You don't say how long ago it was that you set up a repayment plan. But the fact that you are currently paying what you owe as agreed in the repayment plan is a positive for your credit report. The initial delinquency will affect your score less and less as you continue to make on-time payments. The impact from the delinquent account will fade within two years from when you started paying regularly.
What you may need to do to boost your credit score is add some positive accounts to your credit file, such as a revolving credit account or two. You state you have a car loan, and I presume you are paying it on time and as agreed. That type of positive installment loan can help improve your credit score, but you also need to illustrate that you can handle a revolving account like a credit card.
You can visit MyFico.com to learn more about how your credit score is calculated and how to bring up your score. Your traditional FICO credit score is determined based on your payment history (35 percent); amounts owed (30 percent); length of credit history (15 percent); new credit (10 percent); and types of credit used (10 percent).
To get a picture of where you stand as a potential mortgage applicant, I suggest you consider obtaining free copies of your credit reports from AnnualCreditReport.com. Requesting them will not lower your score. Next, take them to a loan officer at the bank or credit union where you have an existing relationship. Let your banker know that you are interested in buying a house in the future, and find out how you need to work on your credit in order to qualify for an affordable home loan. I believe you will be pleasantly surprised at the answer.
