Need help

Hi all, we are first time home buyers in bay area. We are in contract for a property and working with a lender for our loan. Our debt to income was coming at 47% and lender asked us to do more down payment. We can bring our DTI (debt to income) to no lower than 44. Do you think it will be okay? Has anyone ever been denied a loan at this DTI? Any answers would be helpful. Thank you in advance! Edit - it is a conventional 7 year ARM loan
