Congrats on the new gig! Wonderful news for you & spouse!

What can you do? That's really a matter of the math and what you're willing to give up. You and your spouse need to be on the same page here, because either one of you can sink the plan. A plan has to be executable or it is done as soon as the ink on the paper is dry. Be balanced, not punitive.

If you aren't already, consider a very strict budget and understand where ever single cent in and out of your checking acct is going. Doing this will help you understand where your money is going and what choices you are willing to make. What are the expenses that can be removed, reduced? Is there an expensive car? Is there a better rental option?
