If you’ve ever thought of using your credit card for a down payment of any kind, think again. It’s not a great idea to use a credit card for a down payment on items such as cars, or large appliances.
You are only adding more debt on top of the price of the already expensive item. And, the large purchase could have a negative effect on your credit score. If your card balance is higher than your credit limit, your score will take a hit. This is the same level of damage of a missed payment.
Here’s a rule of thumb, if you’re using the credit card because of the high credit card limit it gives you that means you probably can’t really afford the item you’re trying to purchase. If you don’t have the actual money for the down payment on what you want, it’s best to go without it.
