During escrow you are under a microscope so be aware.  During this time it is not advised to make large purchases like, buying a new car or booking that dream vacation.  Even the smallest thing can change your loan application and set up red flags with the mortgage underwriter.  You want your debt to income ration to stay the same as when you were pre-approved for the loan.  Before closing they do a final credit pull so anything new will show up and you don't want any changes happening when you are about to cross the finish line!
