Frequently asked questions

What is the difference between pre-qualification and pre-approval?

Pre-qualification is an informal estimate of how much you might borrow, based on self-reported income and debts. Pre-approval involves a formal application, credit check, and document verification — it's a much stronger signal to sellers. This calculator provides a pre-qualification estimate only.

How much mortgage can I qualify for with a $100,000 income?

With $100,000 annual income ($8,333/month), you can typically afford up to $2,333/month in housing costs (28% front-end ratio). At 7% interest, that's roughly a $350,000 mortgage — or a $400,000 home with a 12.5% down payment. Existing debts reduce this amount.

Does pre-qualification affect my credit score?

This calculator does not affect your credit score — it's purely a math exercise. Formal pre-qualification or pre-approval from a lender may involve a soft pull (no impact) or hard pull (small temporary impact). Ask your lender which type they use.
