If your repayment term is extended when you consolidate, it may take you significantly longer to pay off your credit card debt. While it may be nice to have a more manageable monthly payment, it also means paying more interest over the life of the loan. Review the terms of your consolidation carefully before deciding that it is the right choice for you.
It may not make sense but that is the way it’s factored into your credit score, which is the end result here. Cutting up the card to avoid using it may help if it’s a temptation. The scores are comprised of debt to income ratio, but also credit worthiness and longevity, among many other things. If you have $100k in open to buy credit, and only $5k in debt, that helps your score. Also, it shows that lenders have extended this amount of credit to you. i.e. Creditworthiness. Additionally, your score factors in length of credit. They want to see how long you’ve kept that credit, expecting a good relationship with the lender and you’ve shown responsibility. Old schoolers used to close the accts and be done with it. This is the new way of the credit score. It is an education in itself.
