When house shopping did you use any online affordability/mortgage calculators, and were their estimates close to what you were actually approved for? A few people I know have had pretty different loan amounts pre-approved than what the calculators said. I'm aware that they're just estimates, but I'm curious to hear how accurate they are/were for you! We're getting our ducks in a row to buy this fall - eek!

ETA: I'm asking more about calculators that determine how much house you can afford and factor in debt-to-income ratio, etc.
