Does a Mortgage Inquiry Affect Your Credit Score?

Applying for a mortgage does affect your credit score, but the impact is smaller than most people expect. A single hard inquiry from a mortgage lender takes fewer than five points off a typical FICO score, stops counting toward your score after 12 months, and disappears from your credit report entirely after two years.¹ Scoring models also give mortgage shoppers a built-in window to compare offers from multiple lenders without stacking up damage.

Soft Pulls and Hard Pulls Are Not the Same

Only one kind of credit check actually moves your score. When you get prequalified, the lender runs a soft inquiry. It shows up on your personal credit file, but other creditors can’t see it and it has zero effect on your score. Prequalification is a casual look at your finances to estimate a loan amount, with no commitment either way.

Preapproval is the step that costs you points. The lender pulls your full credit report through a hard inquiry, reviews your income and debts, and issues a letter stating how much you’re approved to borrow. Federal law requires a permissible purpose for that pull, and a mortgage application qualifies because the lender is evaluating you for a credit transaction.² The hard inquiry then gets recorded by all three national credit bureaus: Equifax, Experian, and TransUnion.³

How Many Points You Actually Lose

For most borrowers, a single hard mortgage inquiry costs fewer than five FICO points.¹ Inquiries sit in the “new credit” category, which makes up about 10 percent of your FICO score. Payment history and how much of your available credit you’re using carry far more weight.⁴

Long credit history and a high score cushion the effect further. Thinner files and lower scores feel it a bit more, because each data point carries more weight when there’s less history to balance it out. Either way, the mortgage inquiry by itself almost never decides an approval. Lenders weigh your debt-to-income ratio, payment track record, and credit utilization far more heavily.

Shopping Multiple Lenders Without Stacking Up Damage

FICO builds in a two-layer shield for mortgage shoppers. Any mortgage-related hard inquiry made within the 30 days before your score is calculated is ignored entirely.⁵ That 30-day buffer means you can apply with several lenders right before a score is pulled and see no impact at all.

Once inquiries age past that buffer, multiple mortgage pulls within a defined window are collapsed into a single inquiry for scoring purposes. Newer FICO versions use a 45-day window; older versions use 14 days.⁶ The CFPB confirms the 45-day window and says the score impact is the same whether you consult one lender or ten, as long as the last credit check falls within 45 days of the first.⁷

VantageScore uses a 14-day rolling window where multiple mortgage inquiries are treated as a single event.⁸ The practical move is to compress your mortgage shopping into a tight window. Get all your applications in within two weeks and you’re safely inside every scoring model’s protection. The CFPB itself encourages shopping around, noting that even if you spill past the window, the cost of an extra inquiry is usually worth what you save on a better rate.⁷

How Long a Mortgage Inquiry Sticks Around

A hard mortgage inquiry affects your FICO score for 12 months. After that, the scoring model stops counting it, even though the inquiry itself stays visible on your credit report for a full two years.¹ The extra year of visibility rarely matters. Other lenders can still see that you applied, but past the 12-month mark the inquiry has no weight in your score. Most borrowers find the small dip has already recovered well before the year is up, especially with on-time payments and low balances.

The Bigger Risk: New Credit While Your Mortgage Is in Underwriting

The mortgage inquiry itself barely moves the needle. Opening a new credit card, financing furniture, or taking out a car loan while your mortgage is in underwriting is a different story. Each new account generates its own hard inquiry, lowers your average account age, and changes your debt-to-income ratio. If the resulting drop pushes you into a lower credit tier, the lender may raise your rate or pull the approval outright.

Lenders also pull your credit a second time right before closing. Any new accounts or balances that appeared since your application raise red flags with the underwriter, and the process stalls while they investigate. The safest approach is to avoid applying for any new credit from a few months before your mortgage application through the day you close.

Disputing an Unauthorized Inquiry

If a hard inquiry shows up on your credit report that you didn’t authorize, you can challenge it. Contact the credit bureau reporting the inquiry in writing, explain what you’re disputing and why, and include copies of any supporting documents. The bureau must investigate and report back.⁹

Also contact the company that made the inquiry. Send a written dispute by certified mail. The company generally has 30 days to investigate, and if it can’t verify the inquiry was authorized, it must tell the credit bureaus to remove it.⁹ Cleaning up unauthorized inquiries is worth it not just for the few points they cost, but because unexplained entries invite questions from an underwriter and slow your closing down.
