this is a very open question :) and really no one can say if 'you can make it' on your financials.
figure around 2K per month basically. some higher, some can do it lower actually but I think around 2K is a very safe cost.
DO IT!! just do a month or 2 and see exactly what it costs, where you are drawing the money to pay for it and is it all worth it to you guys...cause there is not one guarantee in this life that you will live to pay off all your debt and life stands still for no one. It really is about how you want to live your life and what risks you are willing to take to make it happen :)
best of luck to you!!
