"How Do I Keep My Pre-Approval Current While I'm Still Shopping?"

Keep four things current and the letter itself is a quick reissue: credit, income, assets, and employment. A pre-approval goes stale because the evidence behind it has an age limit measured against the day your loan closes, not the day the letter was written. Replace the oldest document every couple of months, and say something when your income, debts, or job change.

I'm Jeff Moran, a mortgage broker in Bluffton, South Carolina, originating since 1996, licensed in fifteen states, NMLS #483943, through C2 Financial Corporation.

Most people I talk to who are nine weeks into a search have a letter in their email from the first week of it. They are not sure whether it still counts, and they are reluctant to ask, because the first time around involved a week of gathering paperwork and they do not want to do that again on a Friday afternoon. The good news is that a refresh and a first application are two different amounts of work.

Is it the letter that expires, or the file behind it?

The file. The letter just carries a date.

My letters run ninety days, and that date is a choice, not a rule handed down from anywhere. I picked it because it fits comfortably inside the age limits underwriting applies to the documents in your file, so a letter that is still inside its ninety days is almost always backed by evidence that is still usable. The full explanation of what the letter is and how it gets built lives on the pre-approval letter page.

What that means in practice: when the ninety days runs out, nothing is revoked and nothing resets. The question a new letter asks is narrow. Is the evidence still current, and has anything material changed since we looked?

Why does a lender care how old my documents are?

Because the file gets judged against the day it funds.

Fannie Mae writes the rule down. Credit documents must be no more than four months old on the note date, which is the day you sign, and when the file holds two consecutive documents of the same kind, the most recent one is the one measured. If a document is older than that on the note date, the lender has to update it (Selling Guide B1-1-03, Allowable Age of Credit Documents and Federal Income Tax Returns, revised 04/02/2025). Each agency sets its own version of this, and an individual lender is free to be tighter than the agency it sells to.

Read that with the calendar in mind and the shape of the problem shows up. The clock runs to closing, not to your offer. A pay stub that looks fresh the week you write an offer can be too old by the week you sign, because a purchase file usually spends a month or more between those two dates.

That is also why the answer to "is my letter still good" is sometimes yes on a home closing in three weeks and no on the same day for a new build finishing in the spring.

What does a refresh actually re-verify?

Four buckets, and usually only the ones that moved.

Credit. A new report and new scores. On a pre-approval this is a soft pull, which is the whole reason the first one was painless, and a soft pull does not affect your score at all. What I am reading is whether balances moved, whether anything new opened, and whether a monthly obligation appeared that changes the ratio math. If you want the arithmetic itself, how debt-to-income gets calculated walks through it.

Income. The most recent pay stub, and a W-2 if we have crossed into a new year since the file was built. Salary is read as current salary from an active employer, so a January refresh on a file built in October may want the new year's numbers rather than last year's.

Assets. The newest bank or investment statement showing the down payment and closing money. This is the bucket that ages fastest, because statements arrive monthly and the four month clock still runs to the note date.

Employment. Confirmation that the job is still the job. The formal version of this happens close to closing on a live file, and making employment verification easy before closing covers how that step actually works.

What does not get redone: the structure of the file. The program, the way self-employed income was calculated, the analysis of your returns, the automated underwriting run. Those stand unless something underneath them changed. A refresh is a fresh set of evidence for the same conclusion, which is why it takes an afternoon instead of a week.

What can I keep current while I shop?

One folder, four things, refreshed on a rhythm instead of in a panic.

1. Save every pay stub as it comes. Two minutes a pay period. When a refresh comes up, the newest one is already there.
2. Download each month's bank statement as a PDF the week it posts. Not a screenshot and not a printed balance page. The statement with your name, the account number, and the full period on it is the document underwriting reads.
3. Keep large deposits explainable while the explanation is easy. The paper trail on a transfer is simple to build the week it lands and annoying to reconstruct four months later. Which bank deposits an underwriter will ask you to explain is the detail on which ones matter.
4. Tell me about a change the week it happens, not the week it shows up. A new car payment, a bonus, a promotion, a co-signed loan for a family member. Small things on your end are ratio changes on mine, and every one of them is easier to plan around early.
5. Ask for a new letter before an offer weekend, not during one. A reissue is quick when it is a reissue. It stops being quick when it turns out a document aged out and nobody looked until Saturday morning.

Buyers who do these five things get a refreshed letter the same day they ask. Buyers who do none of them spend two days gathering before the letter can be written, which is fine in a quiet week and expensive in the week you finally find the home.

When is a refresh more than a refresh?

Four situations turn it into a real second look, and all four are worth knowing in advance.

A job change. New employer, new pay structure, commission or bonus where there was salary before. Continuance is the question underwriting asks about any income, so a change in how you are paid gets re-evaluated rather than re-stamped.

New debt. A car, a credit line, a co-signed loan, furniture financing for the home you have not bought yet. The payment lands on the ratio and the price range moves with it.

A raise or a new income source. This one usually helps, and it still has to be documented in a specific way to be usable. What a raise after pre-approval is worth, and when it counts covers the timing.

A gap in employment, or a move to self-employment. Both are normal files, and both are documented differently than a W-2 job. Getting pre-approved covers what a full review looks at when that is the starting point.

None of these disqualify anybody. They are just the four cases where I would rather look at the whole picture again than reprint a letter and hope.

The mistakes that cost the most time

Letting the letter lapse and assuming a lapse is a problem. It is paperwork, not a verdict. Ask for the new one.

Waiting for an accepted offer to sort the documents out. Once you are under contract there is a closing date attached to the calendar, and the four month clock is now measured against a real day rather than a hypothetical one. Every document you had to chase is chased against a deadline.

Sending a screenshot of a banking app instead of a statement. It shows a balance and almost nothing else. The statement is what gets read, and pulling it takes about the same thirty seconds.

Moving money between accounts during the search. Not forbidden, just documentable. Every transfer becomes a deposit somewhere that has to be explained.

Opening a card for the furniture before closing. A new tradeline is a new payment and a new inquiry at the exact moment your ratio is being re-measured.

Shopping a letter from one lender while planning to close with another. That is a real option and it has its own mechanics. Switching lenders after pre-approval is the honest version of how that works.

An illustration

Numbers and dates below are made up to show the mechanism. They are not a quote and not a statement about what any particular file produces.

Say your file was built in the spring. The newest pay stub in it is dated May 2. You write an offer on September 8 and the contract sets closing for October 20.

Oldest credit document in the file          May 2
Four months from that date                  September 2
Scheduled note date                          October 20
                                            -----------
Document age on the note date                Too old

What the refresh needs                       One current stub
                                             One current statement
                                             A fresh credit report
Time it takes when they are saved            Same day
Time it takes when they are not              Two to three days

The stub was already past the line on the day you wrote the offer, and nothing about that was visible from looking at the letter, because the letter had a June date on it and looked fine. That is the whole point of the tape. The letter's date and the file's date are two different clocks, and the one that decides anything is measured against closing.

What to do this week

Open your email, find the letter, and look at the date on it. If it is inside ninety days and your pay stub and bank statement are both from the last two months, you are current and you can stop reading.

If either one is older than that, save this month's stub and this month's statement into one folder and ask for a refreshed letter. It is a short conversation, and doing it on a Tuesday when nothing is happening costs you nothing.

Then price the scenario you are actually shopping. Run your numbers and you will see rates priced for your own file, your debt ratio, and closing costs built against your state's real practice. No credit pull, no account, nobody calls you.

Nothing here is a loan approval, a denial, or a commitment to lend. Document age requirements come from the agency that will own the loan and from the lender making it, and the current text of any guideline section belongs to the agency that publishes it.

Common questions

How long is a mortgage pre-approval good for?

Most lenders date a pre-approval letter sixty to ninety days out, and that date is the lender's choice rather than a published rule. Mine run ninety days. Underneath it is the rule that matters: Fannie Mae requires credit documents to be no more than four months old on the note date, the day you sign (Selling Guide B1-1-03, revised 04/02/2025). A letter inside its window is almost always backed by documents still inside theirs, which is why the two dates usually agree. When the letter runs out, it gets reissued rather than rebuilt, as long as nothing material has changed.

Does renewing a pre-approval hurt my credit?

A pre-approval refresh with me starts with a soft credit pull, and a soft pull does not affect your score. That is true of the first one and of every refresh after it. A hard inquiry happens later, on a live application, and even then the scoring models treat mortgage inquiries inside a shopping window as a single event. If the credit pull is the thing that has kept you from asking for a current letter, that concern is solvable in about five minutes.

What happens if my pre-approval expires before I find a house?

Nothing is revoked and nothing resets. The letter is dated evidence that a review happened, so an expired one means the evidence needs refreshing, not that the review was undone. Ask for a new letter, send the current pay stub and the current bank statement, and the new one is usually written the same day. Searches that run six or nine months are ordinary, and a letter getting reissued two or three times along the way is ordinary with them.

Do I have to send all my documents again to renew a pre-approval?

Usually just the ones that aged. The analysis stays: the program, the income calculation, the read on your tax returns if you are self-employed. What gets replaced is the evidence with a date on it, which in most files is the newest pay stub, the newest bank statement, and a current credit report. If your income structure or your debts changed since the file was built, that part gets looked at properly rather than carried forward, which is a different conversation and still not a second application.

Will my pre-approval amount change when it is refreshed?

It can move in either direction, and the reason is always something specific rather than a policy. A new monthly payment, a change in how you are paid, a different balance on a card, or pricing that has moved since the file was built. That is one of the arguments for refreshing on a rhythm instead of at the last minute: if the number moved, you would rather learn it on a quiet Tuesday than on the day you are deciding what to offer on a home.

Should I get pre-approved if I am not buying for another six months?

Carrying a letter while you are still a year out costs you nothing, and it buys the one thing that is hard to get later: time. Anything in the file that needs work, an old collection, a debt you forgot you co-signed, income that documents differently than it feels, is a chore when you find it six months early and a crisis when you find it during closing week. The letter gets reissued when the timing arrives.
