It was around $60k+ at one stage and he sold an investment property/old PPOR to lower the debt.
He will get out of it eventually, I mean, his on a huge income (over $150k a year gross). But any ways of refinancing the debt to a lower rate are helpful at this stage.
I leant my friend the book, "I will teach you to be rich" by Ramit Sethi in the hope it will change his spending habits.
In that case he should be Ok....If he was on less than $50k it would be somewhat of a crisis.
I'm also in that ballpark income and had a CC debt of over $20k 2 years ago which arose due to a balance transfer on 2 other cards as well as my car loan. The balance transfer was 0% for 6 months , after which time it was 11%(which was more cost effective than a car loan at 12%) . The CC was not used for day to day expenses but was paid off religeously at around $1,200-$1,300 a month ....Admittedly it took 18months to pay off but it was no stress even after paying my ex wife child support of around $2k a month.
Tell him to get a card with a low % balance transfer and put in place a payment plan and stick to it.
