When you buy a new home, you need a mortgage to purchase it. And before you get a mortgage, you need to determine how much mortgage you qualify for. Different sources may qualify you for different mortgage amounts. And how much you qualify for does not necessarily equate to how much you can afford.
How much you can afford is based on your personal budget. When a mortgage lender tells you how much you can qualify for, that is the highest mortgage amount they’ll approve you for. But this may not be the mortgage size you end up closing on.
