If you have a good credit score, you should be able to get a credit card with a zero percent interest rate. That can come in handy for surprise home repairs. The trick is that the zero rate is good only for a set introductory period of a year or so, which means you will need to shop for a new card deal when your old zero teaser rate expires. You'll want to make sure that you don't use the card for anything other than home repairs and that your zero rate applies to new charges (some cards offer the no-rate option only on balances transferred from other cards). The Discover Platinum card comes with a zero rate on new purchases for one year, while American Express Blue offers a similar deal for the first 15 months.
