Ok, I am on the fence here. we have a card payment that is 0% finance (replaced an appliance) until May 24th. After that, they will tack on the past years interest. There is $1800, which is what I pay for my mortgage/taxes/insurance. I usually pay mortgage early. Is it completely wrong if I delay my June mortgage until June 5th (still fine)? Once this is paid off, we should be able to refinance the house too, just won't lose PMI. With July being an extra week, I will be back to paying before the start of August.
