I think it depends on your financial situation and your plans for the next couple of years. Obviously if you rent or buy, it's going to cost you more moeny, whereas if you borrow, all you're doing is taking away points from the forthcoming year.
We're doing that this year, but what I've done is work out what we plan to do with our points for 05/06, 06/07 and even 07/08 to see if eventually it all evens out - and it does, so for us, borrowing works out fine. That might be the best thing to do - plan out how you want to use your points for the next couple of years and if you've still got enough to do everything you want to do after borrowing, then that's the route to go down. If not, you may have to look at renting.
What plans have you got? I'd love to hear about them!
