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.
What documents do I need for mortgage pre-approval?
Typical pre-approval documents include: 2 years of W-2s and tax returns, recent pay stubs (30 days), 2–3 months of bank and investment statements, photo ID, and your Social Security number for a credit pull. Self-employed borrowers also need business tax returns and a year-to-date profit and loss statement.
How long does mortgage pre-approval last?
Most pre-approval letters are valid for 60–90 days. After that, lenders typically require updated income documents and may re-pull credit. If your home search extends beyond 90 days, ask your lender to refresh your pre-approval letter — it's usually a quick update, not a full new application.
