Have you thought about getting a personal loan rather than using your credit cards? The interest rates charged for loans can be less than rates on credit cards.
Before applying for a loan work out how much you can repay monthly and look for one that falls into that category, taking into account the interest and or set up charges that may be applied to that loan.
Never sign a loan agreement without first carefully reading the terms and conditions to ensure you are getting the type of loan you want. Look further than just the nmonthly payments, it is the total cost of the laon you should consider and compare against others.
