How to Get Preapproved for a Mortgage: Steps, Documents, Timeline
What preapproval involves, the documents lenders ask for, how long it takes and lasts, and the mistakes that cost people their approval before closing.
Key takeaways
- Prequalification is an estimate; preapproval involves verified documents and a credit pull.
- Most preapproval letters are valid for 60 to 90 days.
- Rate-shopping multiple lenders in a short window typically counts as a single credit inquiry.
- Preapproval is conditional — new debt or a job change before closing can void it.

Preapproval versus prequalification
Two very different pieces of paper
| Prequalification | Preapproval | |
|---|---|---|
| Information used | Self-reported | Documented and verified |
| Credit check | Soft or none | Hard inquiry |
| Typical turnaround | Minutes | One to several days |
| Weight with sellers | Low | Expected on competitive offers |
Before you apply
- Pull your credit reports and dispute any errors — corrections take weeks.
- Pay down revolving balances; utilisation moves scores quickly.
- Leave large deposits and new credit accounts alone until closing.
- Assemble the paperwork below so nothing stalls mid-application.
Documents lenders normally request
- Photo ID and Social Security number.
- Two most recent pay stubs, or two years of tax returns if self-employed.
- W-2s or 1099s covering the last two years.
- Two to three months of bank and investment statements.
- Documentation for any gift funds toward the down payment.
- Records of other debts: car loans, student loans, credit cards.
The process, end to end
Typical preapproval timeline
| Stage | What happens | Typical duration |
|---|---|---|
| Application | Submit details and authorise a credit pull | Under an hour |
| Document review | Lender verifies income, assets, employment | 1–3 business days |
| Underwriting decision | Conditional approval issued | 1–5 business days |
| Preapproval letter | States the maximum loan and conditions | Same day as decision |
Shop more than one lender
Credit scoring models treat multiple mortgage inquiries within a short shopping window as a single event, so comparing three or four lenders does not compound the credit impact. Compare the Loan Estimates side by side on rate, APR, origination fees, and lender credits. Model the outcome first with the mortgage payment calculator and the closing cost calculator.

Frequently asked questions
How long does mortgage preapproval take?
Typically one to five business days once complete documents are submitted. Some lenders issue automated preapprovals within hours, but those still depend on later document verification.
How long is a preapproval letter good for?
Usually 60 to 90 days, because credit and income data go stale. Renewal generally requires updated pay stubs and a fresh credit check.
Does preapproval hurt your credit score?
A hard inquiry has a small, short-lived effect. Multiple mortgage inquiries inside the shopping window are generally counted once, so comparing lenders is not penalised.
Can you be denied after preapproval?
Yes. Preapproval is conditional on nothing material changing and on the property appraising adequately. New debt, income changes, or a low appraisal can all derail it.

About the author
Legamoney is an independent publisher of explanatory guides on borrowing, insurance, personal finance and everyday consumer legal questions. Articles are written by the editorial team rather than by a single named contributor, and they are built from published rules and data from regulators and government agencies — not from opinion or industry marketing. Every guide lists the sources it was written from, shows its arithmetic in full where numbers are involved, and carries publication and update dates so you can judge how current it is. We do not sell financial products, take commission on referrals, or let commercial relationships influence coverage.
How this article was checked
- Every factual claim is traced to a named regulator, government agency, or the provider's own published terms before publication.

- All worked examples are arithmetic shown in full, so a reader can reproduce the result independently.
