How Long Does a Pre-Approval Letter Last?
Standard pre-approval letters are valid for 60 to 90 days from issue, after which the lender refreshes the credit pull and income verification. The FICO rate-shopping window (14-45 days depending on the model) lets you compare multiple lenders without a score penalty. This page walks through validity periods, what triggers re-verification, rate-shopping mechanics, and the right timing for pre-approval relative to your house-hunting plans.
All figures as of May 2026. FICO scoring rules per the FICO Score 8/9/10 model documentation; mortgage refresh practices per Fannie Mae Selling Guide sections B3 and B5.
Quick Answer for Validity
Standard pre-approval validity: 60-90 days
FICO rate-shopping window: 14-45 days
Refresh typically uses soft pull, no score impact. As of May 2026.
The 60-90 Day Standard
Most major lenders set pre-approval validity at 60-90 days. Some prefer the shorter 60-day window because it pushes borrowers to refresh income and credit before expiry, reducing the risk of stale data on file when a property is identified. Other lenders set 90 days because it matches typical house-hunting timelines and reduces the administrative burden of frequent refreshes. The validity period is stated on the letter itself, sometimes with a specific expiration date.
The validity window is not regulatory; it is lender policy. The CFPB and HUD do not specify a maximum pre-approval validity period. The 60-90 day standard exists because lender risk management practices typically require fresh credit pull and income verification within that window before final loan approval.
When the letter expires, the lender refreshes: pulls a current credit report (usually soft pull within 90-120 days of initial hard pull), requests current paystubs and bank statements, and re-runs the Automated Underwriting System. If nothing material has changed, the refreshed letter issues at the same amount within a few hours. If credit score has dropped or income has changed, the refresh can result in a lower, identical, or higher pre-approval amount.
What Triggers an Unscheduled Re-Verification
Lenders re-verify employment via verbal contact at submission and again 10 days before closing. The 10-day pre-close verification catches employment changes that occurred during the loan process. Other events that trigger re-verification within the validity window include:
- Change of employer or role (always requires fresh income docs and an LOE)
- Change in pay structure (W-2 to 1099, base to commission, addition of bonus)
- New monthly debt obligation that affects DTI (car loan, student loan refinance)
- New large bank deposit that triggers sourcing requirement
- Material drop in credit score (10+ points) caught at refresh
- Major life event (marriage, divorce, birth of dependent) that changes filing status
Re-verification is administratively quick (most items resolve in 24-72 hours) but each one is a friction point that can delay the offer-to-closing timeline. The fewer changes you make between pre-approval and closing, the smoother the process.
FICO Rate-Shopping Window Mechanics
FICO scoring treats multiple mortgage inquiries within a defined window as a single inquiry, recognising that borrowers shop multiple lenders for the same loan. The window varies by FICO model: FICO 4 uses 14 days, FICO 8 uses 45 days, FICO 9 and FICO 10 use 45 days. Most mortgage lenders pull FICO 4 (the legacy mortgage industry model), so the conservative answer is 14 days.
Practical implementation: complete all mortgage credit pulls within 14 days of the first one. This lets you shop 3-5 lenders, compare quotes, and pick the best execution without score damage. The hard inquiry from the first pull still appears on the credit report, but additional inquiries within the 14-day window do not stack the score penalty.
What does not count as the rate-shopping window: auto loan pulls, credit card pulls, retail finance pulls. These are separate inquiry categories. Mixing types within the window does not protect you; each inquiry type counts on its own.
The FICO score impact of a single mortgage inquiry is typically 5-10 points for borrowers with strong credit profiles, less for thin-file borrowers, and recovers fully within 6-12 months. Multiple inquiries within the rate-shopping window also recover at the same rate.
Timing: When to Get Pre-Approved
The sweet spot is 30-60 days before you expect to make serious offers. Pre-approving 90+ days early risks letter expiration just as you reach the offer stage, requiring a refresh. Pre-approving the day-of can lose competitive offers where the seller expects pre-approval within hours.
Specific scenarios:
- Just-starting search: Get a preliminary pre-qualification (no hard pull) to know your budget. Refresh to formal pre-approval when you start making offers.
- 30-60 days from offers: Get formal pre-approval with full document submission. Shop 3-5 lenders within 14 days to compare quotes.
- Active offer-making (60-90 days): Pre-approval letter in hand at submission. Refresh if approaching expiration.
- Competitive market: Pre-underwritten approval (lender has reviewed the file beyond standard pre-approval) signals seriousness in multiple-bid situations.
In competitive bidding situations, some lenders offer Fully Underwritten Pre-Approval (sometimes called Conditional Approval or Underwritten Pre-Approval). This is a step beyond standard pre-approval, where the lender's underwriter has reviewed the file and approved the borrower subject only to a clean property appraisal and title. These letters carry more weight with sellers and can win over a standard pre-approval in tight markets.
After a Decline: What to Do
If your pre-approval application is declined, the lender must send a written Adverse Action Notice within 30 days, citing the specific reasons (per the Equal Credit Opportunity Act, 15 USC 1691). Common reasons: insufficient income for the requested amount, credit score below program minimum, DTI above ceiling, insufficient employment history, recent derogatory credit (late payments, collections, charge-offs).
The Adverse Action Notice is a roadmap. If income was the issue, the path forward is either applying for a smaller amount, finding a co-borrower with additional income, or waiting until income increases. If credit was the issue, the path is 90-180 days of credit work (paying down utilisation, removing inaccuracies, ageing the file) before re-applying. If DTI was the issue, the path is paying off the highest monthly debt obligation (often a car) to free up DTI capacity.
A decline from one lender does not mean decline from all lenders. Lender overlays vary; one lender's overlay-driven decline may pass at a different lender's program-minimum standards. After a decline, shopping 2-3 different lenders (within the 14-day window to protect FICO) is worth trying. If multiple lenders decline for similar reasons, the issue is structural and credit/DTI/income work is needed.
Frequently Asked Questions
How long does a mortgage pre-approval letter last?
Standard pre-approval letters are valid for 60-90 days from issue. Some lenders set 60 days, others 90 days, depending on internal policy and the specific loan program. After expiration, the lender refreshes the credit pull (a soft pull in most cases), updates income verification (most recent paystubs and bank statements), and reissues the letter. The borrower's FICO score and DTI are recalculated; the letter may issue at a higher, lower, or identical amount depending on what has changed.
What is the FICO rate-shopping window?
FICO scoring treats multiple mortgage credit inquiries within a single window as one inquiry for scoring purposes. The window is 14 days for older FICO models (FICO 4) and 45 days for newer ones (FICO 8, FICO 9, FICO 10). Most mortgage lenders use FICO 4 or FICO 5 (which uses 14 days). To stay safest, complete all mortgage credit pulls within 14 days of the first one. This lets you shop 3-5 lenders without any score penalty.
Does my credit score affect pre-approval validity?
Yes, indirectly. If your credit score drops between initial pre-approval and refresh (due to new debt, missed payment, or large purchase), the lender may issue the refreshed letter at a lower amount, change the rate quote, or in extreme cases decline to re-approve. The most common cause of a refresh decline is a new car loan or a major credit card purchase between pre-approval and offer. The unwritten rule is to make no new credit applications or major purchases between pre-approval and closing.
What if my income or employment changes during the validity window?
Any change in employment (resignation, layoff, change of employer, role change) requires a fresh income verification and may require a Letter of Explanation. The lender re-verifies employment at submission and again 10 days before closing (verbal verification). A change in employer often pauses pre-approval until you complete 30-60 days at the new employer (more if a probationary period applies). Salary increases generally help and require updated paystubs; salary decreases or transitions to commission can shrink the pre-approval amount.
Can I refresh my pre-approval letter without a hard credit pull?
Yes, in most cases. Once the lender has your initial hard pull, subsequent refreshes within 90-120 days typically use a soft pull (no score impact). If you have not been in the lender's system for 90+ days, a fresh hard pull may be needed. Most lenders disclose this at the refresh request. Always confirm before authorising.
When should I get pre-approved relative to house-hunting timeline?
Roughly 30-60 days before you expect to make offers. If you pre-approve too early (90+ days before offers), the letter may expire and require refresh just as you reach the offer stage. If you pre-approve too late (week-of offers), you may miss out on competitive bidding situations where pre-approval is expected within hours. The sweet spot is to pre-approve when you start seriously looking, with a plan to refresh once at the 60-day mark if you have not yet found a property.
Is a pre-approval letter binding on the lender?
No, it is conditional. The pre-approval letter is the lender's good-faith commitment to underwrite at the stated amount, subject to verification of all stated conditions (employment, income, assets, credit, property appraisal, title, insurance). Final loan approval comes after submission of the full file post-offer, completion of the appraisal, and clearance of all underwriting conditions. The lender can still decline if any verification fails or if conditions change between pre-approval and final approval.
