Does Getting Pre-Approved Hurt Your Credit Score?
By Jeff Moran, NMLS #483943 · August 29, 2026
A soft credit pull does nothing to your score at all — not a point, not ever. A hard pull typically costs most people fewer than five points, and multiple mortgage pulls inside a shopping window count as one. That is the whole answer, and it is why the fear of getting pre-approved usually costs people more than the pull ever would.

But there is a detail almost every article on this gets wrong, and it matters enough to lead with. The famous 45-day rate-shopping window is not the window that applies to mortgages. The scores mortgage lenders actually pull use a 14-day window. If you shop across six weeks on the strength of the 45-day advice, you can take more than one hit.
Here is the real version.
Soft pull versus hard pull, and which one starts this
These are two different things, and the difference is the reason a pre-approval does not have to cost you anything.
A soft pull is a review of your credit that is visible only to you. It does not appear to other lenders and it has no effect on your score whatsoever. It is the same class of event as checking your own credit, or the pre-screened offers that arrive in the mail.
A hard pull is an inquiry recorded because you applied for credit. It is visible to other lenders and it is a scoring factor — a small one.
That distinction is the useful part: a soft pull is enough to produce a real letter. I can see your actual credit report — the real balances, the real accounts, the real score — calculate the debt ratio from what is on the report rather than from what you remember, and write you a letter backed by evidence. Without a hard inquiry.
The hard pull comes later, when a file goes to a lender for an actual loan. By then you are not shopping any more, and by then you have a letter that told you where you stood before you spent a weekend at open houses.
What a hard pull actually costs, in points
When the time does come, the number is smaller than the anxiety around it.
FICO's own guidance is that one additional inquiry takes fewer than five points off the score for most people. It affects people with short credit histories or very few accounts more than it affects everyone else, which is worth knowing if you are young or new to credit — but "fewer than five points" is the honest baseline.
Set that against what a quarter-point difference in rate costs over a loan you keep for years, and the arithmetic stops being close.
The rate-shopping window — and why the number you have read is wrong
This is the part worth reading twice.
Scoring models know people shop for mortgages. So multiple mortgage inquiries inside a defined window get treated as one event rather than several. Everybody agrees on that much.
The disagreement is the length of the window, and it is not a disagreement — it is two different scoring versions:
- Newer FICO models (FICO 8 and later) use a 45-day window. This is the number almost every article quotes, because it is the number that applies to the score you see on your credit card app or your credit monitoring service.
- Older FICO models use a 14-day window. And the scores mortgage lenders pull — FICO Score 2 at Experian, FICO Score 4 at TransUnion, FICO Score 5 at Equifax — are those older versions.
So for a mortgage, the protective window is 14 days, not 45.
You will generally not be told which model a given lender uses, and you have no way to check. Which makes the safe practice simple and specific:
Do all of your hard pulls inside the same two weeks. Ideally the same few days.
That is not a hedge. It is the only version of the advice that is correct under every scoring model, and it costs you nothing to follow.
There is a second protection worth knowing about, because it is genuinely generous: FICO ignores mortgage, auto and student loan inquiries made in the 30 days before the score is calculated. So an inquiry from last week may not be counted at all when a score is pulled today.
The score you have been watching is probably not the score
A quiet source of confusion, and it explains a lot of surprised phone calls.
The score on your banking app, your credit card's dashboard, or a free monitoring service is usually a FICO 8 or a VantageScore. The score a mortgage lender pulls is one of the older FICO versions named above.
They are built from the same credit report and they frequently disagree, sometimes by a meaningful margin in either direction. Neither one is wrong; they are different models answering slightly different questions.
The practical consequence: the number you have been watching is a reasonable indicator of direction and a poor predictor of the exact figure a mortgage file will use. That is another argument for having somebody pull the real one early, softly, while nothing is riding on it.
What the letter actually is, and how long it lasts
Once your credit has been reviewed and your income and assets have been looked at, you get a letter. Two things about it that people are rarely told:
It has a shelf life, and it is dated. My letters run 90 days, because that is a comfortable margin inside the age limits underwriting applies to credit documents. When it expires, it does not evaporate — as long as nothing material has changed, it gets reissued.
"Material" means four things: income, credit, assets, and employment. If none of those moved, a reissue is routine paperwork rather than starting over.
That is worth saying plainly because it changes the decision. Getting a letter does not commit you to buying anything, and it does not start a clock you have to beat.
Use it now, or put it in your back pocket
There are two entirely legitimate reasons to do this work, and only one of them involves a house.
You are ready now. You get a documented letter, you know your range, and you can write an offer the same week. A listing agent comparing two offers can tell the difference between a letter backed by a reviewed file and one issued on a phone call, and so can the seller.
You are not ready — and this is still worth doing. Maybe the timing is a year out, maybe you are waiting on a lease, maybe you just want to know. The letter goes in a drawer. What you get is the information: your real range, and whatever needs attention before it matters.
That second case is the one people skip, and it is the one where the work pays best. Every problem in a mortgage file is cheaper when it is found early. A collection account nobody knew about, a co-signed loan counting against a ratio, income that documents differently than it feels — each of those is a chore in January and a crisis in closing week.
Common mistakes
Waiting until you find the house. The worst time to learn your range is after you have emotionally moved in. Everything in this article is easier before there is a property attached to it.
Spreading pulls over a month because an article said 45 days. Covered above. Fourteen days.
Assuming a low score is disqualifying. Programs differ enormously in what they ask, and FHA and conventional price the same file differently. What a score does is change the options and the pricing — and understanding how it changes them is worth more than guessing.
Assuming nothing can be improved. Balances relative to limits move a score faster than almost anything else. What actually moves a score, and how long each thing takes, is knowable rather than mysterious.
Not asking what the letter is based on. A letter issued without a credit report and documents is a prequalification wearing a better name. Ask which one you are holding.
An illustration
Numbers below are made up to show the mechanism.
Two people start looking in the same week.
The first is worried about her credit and puts it off. In March she finds a house, applies in a hurry, and the report shows a medical collection she had never seen. It is resolvable, but it takes three weeks she does not have, and the ratio question nobody asked about in advance turns out to matter.
The second does a soft pull in January. Same collection, found in a week when nothing is riding on it. He deals with it, gets a letter, and does nothing else for four months. In May he writes an offer with a letter behind him and a listing agent who can see it was real.
Same file. Same person, roughly. The only difference is when the information arrived.
Where to start
Run your numbers first — no credit pull, no account, nobody calls you. That gives you rates for your scenario, your debt ratio and closing costs before anybody looks at anything.
When you want the letter behind you, here is what a real pre-approval reviews, and what the letter is worth once you have it.
Nothing here is a credit decision, an approval, or a denial, and no pre-approval from anyone is a loan commitment. Final approval always depends on the property, the appraisal and underwriting the complete file. Scoring models are revised over time; what applies to a specific file is worth confirming rather than assuming.
Common questions
Does a soft credit pull affect my credit score?
No. A soft pull is visible only to you, is not shown to other lenders, and is not a scoring factor at all. It is the same category of event as checking your own credit or receiving a pre-screened offer. That is why a soft pull is enough to review a file and produce a documented letter without an inquiry appearing on your report.
How many points does a mortgage credit pull cost?
FICO's guidance is that one additional inquiry takes fewer than five points off the score for most people, with a larger effect for those who have few accounts or a short credit history. The effect also fades over time. Set against the cost of not comparing options on a loan held for years, a single inquiry is rarely the expensive part of the decision.
How long do I have to shop for a mortgage without extra credit damage?
Fourteen days is the safe answer, and it is shorter than the number most articles give. Multiple mortgage inquiries inside a shopping window are counted as one event, but the window depends on the scoring version: newer FICO models use 45 days while the older models mortgage lenders actually pull — FICO Score 2, 4 and 5 — use 14. Since a consumer cannot tell which model a lender uses, compressing all hard pulls into the same two weeks is the only advice that is correct in every case.
Why is my mortgage credit score different from the score in my banking app?
Because they are different scoring models built from the same report. Consumer apps and monitoring services generally show a FICO 8 or a VantageScore, while mortgage lenders pull FICO Score 2, 4 or 5 — older versions retained across the mortgage industry. They frequently disagree, in either direction. The app score is a fair indicator of direction and a poor predictor of the exact figure a mortgage file will use.
How long is a pre-approval letter good for?
Mine are dated and run 90 days, which sits comfortably inside the age limits underwriting applies to credit documents. Expiry is not a reset: as long as income, credit, assets and employment have not materially changed, the letter is reissued rather than rebuilt. That is why getting one early costs nothing even if the timing turns out to be a year away.
Can I get a pre-approval letter if I am not ready to buy yet?
Yes, and it is often the better time to do it. The letter goes in a drawer; what you keep is the information — your actual range and anything that needs attention before it matters. Problems found while nothing is riding on them are chores. The same problems found during closing week are expensive, and some of them take longer to fix than a contract allows.
