Mortgage Pre-Approval Guide

A mortgage pre-approval tells a seller you can actually complete. Not every letter carries the same weight, and the difference matters in a competitive market.

What a mortgage pre-approval involves

• Pre-qualification is estimated from what you say; pre-approval is verified from documents
• Two years of tax returns, 30 days of pay stubs and two months of bank statements
• The lender pulls credit, which is a hard inquiry
• The letter is usually valid for 60 to 90 days
• You learn your maximum loan amount, an estimated rate and a payment range
• Many Florida sellers will not review an offer without one

Three strengths of letter, and sellers can tell

Ask which one you are getting, because the wording on the page is not the same as the work behind it.

Pre-qualification rests on figures you provided, with nothing verified. It is a useful budgeting exercise and carries little weight with a listing agent.

Standard pre-approval means credit was pulled and income documents reviewed by a loan officer. This is what most buyers hold, and it is usually enough.

Underwritten pre-approval goes further: a real underwriter has reviewed the full file and approved it subject only to a property. Since the only remaining variables are the appraisal and the title, this letter competes closely with a cash offer. It takes a few days longer to obtain and is worth requesting in a multiple-offer market.

Rate shopping does not multiply the damage

Credit scoring models treat multiple mortgage inquiries within a shopping window as a single event. Current FICO versions use 45 days, while some older versions still in use apply 14. Therefore gather every quote inside two weeks and you are safe under either.

Getting more than one pre-approval is normal and sensible. What harms you is spreading the pulls across two months, which reads as repeated separate applications.

A pre-approval is conditional, and stays that way

The letter is not a commitment to lend. Final approval depends on the property appraising, the title being clear, and your circumstances remaining as documented.

Because lenders re-check credit shortly before funding, that last point is the one that catches people. Do not finance a car, open a store card or change jobs between pre-approval and closing. A new monthly payment can push your ratio past the limit and undo an approval days before you move. Read the documents checklist so you can move quickly once you are under contract.

Credit scoring windows differ by model version, so treat 14 days as the conservative assumption. See the CFPB’s owning a home guide for how pre-approval fits the wider process.
