A house can look affordable on paper and still make the rest of your budget miserable. The real question is not how much a lender will approve, but how much you can spend on a home while still paying for groceries, saving money, handling emergencies, and enjoying life without checking the bank account every afternoon.
That distinction matters because a mortgage approval does not know that the car needs new tires, the water heater has been making a suspicious noise, or the kids suddenly need expensive school supplies. A lender sees income, debts, credit history, and other qualifying information. Your household budget has to deal with everything else, which makes your personal affordability number much more useful than a shiny maximum loan amount. The Consumer Financial Protection Bureau specifically warns that qualifying for a mortgage does not necessarily mean you can comfortably afford it.
