Paying rent - out of savings, or on credit card?

Bit of a simple query here... Here's my situation:

- I pay rent fortnightly
- I have a credit card with a 55-day interest-free period... I use it for pretty much all my living expenses, and pay off the entire closing balance each month so I'm never paying interest...
- I have a bunch of savings in Ubank.

In order to maximise the interest earned on the Ubank savings, would it better to:

1) Put rent on the credit card along with other living expenses, and then pay it off monthly as usual; or

2) Schedule a fortnightly internet transfer directly from Ubank to the landlord?

Seems to me that 1) would be better because that way the rent money stays in the account (earning interest) for longer... or is it really much over muchness?

 

I think it depends on what additional cost the landlord changes for credit cards. My real estate office, changes 3%, which is not worth it.

I get 0.8% interest (55days @ 5.72%pa) and 0.5% in reward points (cash vouchers etc.), so unless I can get the credit card change less the 1.5% it is not worth it.

 

Hmmm the surcharge issue was something I hadn't considered... my landlord uses the DEFT system (DEFT) and I've just checked - there's a 1.5% surcharge on Visa payments...

Fortnightly bank transfer it is
