I've been taking advantage of a number of credit card sign-up deals lately in order to build up frequent flyer/reward points.
So far it hasn't had much of an impact on my credit rating, but are there any consequences of this sort of churning that I should be aware of before I go sign up for yet more cards?
Provided you are closing the cards once you are finished with them, the only downside would be the data trail it would be leaving behind you. Financial organisations will be able to see the number of cards you have had then closed and could start turning you away because they are wasting their time and money on you. If you are keeping all the cards, if you ever apply for a home loan or any other form of finance, all those card limits will be considered a debt and liability and reduce your borrowing potential.
