A mortgage pre-approval does lower your credit score, but usually by a small amount and only temporarily

When a lender checks your credit for a mortgage pre-approval, they perform what is called a hard inquiry. This inquiry appears on your credit report and typically drops your score by 5 to 10 points. The exact impact depends on your current score, credit history, and the scoring model used — people with higher scores often see a larger point drop than those starting lower.

The dip is temporary. Most lenders stop counting the inquiry after 12 months, and it falls off your report entirely after two years. If you shop for mortgage rates within 14 to 45 days (the window varies by scoring model), multiple inquiries from different lenders count as a single inquiry, so you do not lose additional points for comparison shopping.

The pre-approval itself — the letter saying a lender will loan you money — does not appear on your credit report at all. Only the inquiry does. This means the pre-approval letter itself cannot hurt your score further.

Key Takeaways

  • A mortgage pre-approval triggers a hard inquiry that typically lowers your score by 5 to 10 points.
  • Multiple rate inquiries within 14 to 45 days count as one inquiry, so shopping around does not multiply the damage.
  • The inquiry stops affecting your score after 12 months and disappears from your report after two years.
  • Closing existing credit accounts or missing payments while pre-approved will hurt your score far more than the inquiry itself.

Why pre-approval requires a hard inquiry instead of a soft one

Lenders distinguish between two types of credit checks. A soft inquiry — the kind used for pre-qualification or when a company checks your credit to send you an offer — does not touch your credit score. A hard inquiry — used for pre-approval, actual loan applications, and credit card applications — does lower your score because it signals you are actively seeking new credit.

Pre-approval requires a hard inquiry because the lender is making a real commitment. They are verifying your income, employment, and debt, not just running a quick screening. They want to know whether you can actually borrow the amount they are promising, which means they need to see your full credit picture. A soft inquiry would not give them enough information to stand behind a pre-approval letter.

This is why pre-qualification (which uses soft inquiries) is free and when ready, while pre-approval takes a few days and costs your score a few points. You are trading a small, temporary score hit for a document that sellers and real estate agents take seriously.

What happens to your score between pre-approval and closing

Once you have a pre-approval letter, your lender will check your credit again before closing — usually a few days before you sign the final paperwork. This second check is also a hard inquiry and will lower your score again by a similar amount. However, lenders expect this second check and build it into their timeline, so it rarely causes problems.

What does cause problems is changing your credit profile between pre-approval and closing. Opening new credit accounts, closing old ones, missing a payment, or running up balances on existing cards can all cause your pre-approval to be withdrawn. Lenders re-check your credit report and debt-to-income ratio before closing, and they are looking for stability, not change.

The safest approach is to treat the period between pre-approval and closing as a freeze on your credit activity. Do not explore for new cards, do not close accounts, do not make large purchases on credit, and do not miss any payments. The lender is not watching your score itself — they are watching your behavior.

How the inquiry affects your score compared to other credit factors

A hard inquiry is one of the smallest factors in your credit score. Payment history (35 percent of your score) and amounts owed (30 percent) matter far more. Missing a single payment will hurt you more than five hard inquiries combined.

This means a mortgage pre-approval is worth the small score hit if you are serious about buying. The inquiry is temporary and minor. What matters more is whether you can actually afford the mortgage and whether you keep paying your other bills on time while you are in the buying process.

If your score is already low — below 620 — a 5 to 10 point drop might matter more because you are closer to the threshold where lenders deny you. In that case, you may want to wait a few months and improve your score before seeking pre-approval. But if your score is 650 or higher, the inquiry is unlikely to change whether you get approved.

What to do if you are shopping for rates from multiple lenders

Most people should get pre-approval from at least two or three lenders to compare rates and terms. The good news is that credit scoring models treat multiple mortgage inquiries as a single inquiry if they happen within a specific window — 14 days for older FICO models, up to 45 days for newer ones.

This means you can contact three lenders in the same week and receive three pre-approval letters without taking three separate hits to your score. The inquiries will show up on your report, but they will count as one for scoring purposes.

To take advantage of this window, do your shopping quickly. Space out your applications over a few days rather than spreading them over a month. Once you have chosen a lender and moved forward with the process, stop shopping — additional inquiries outside the window will each lower your score.

Rebuilding your score after the inquiry

The inquiry itself will not prevent you from rebuilding your score. In fact, the best way to recover those 5 to 10 points is to do the things that matter most: pay all your bills on time and lower the balances on your credit cards.

Paying down credit card balances is especially powerful because it lowers your credit utilization ratio — the percentage of your available credit that you are using. If you have a $5,000 limit and a $4,000 balance, paying it down to $2,000 will raise your score more than waiting for the inquiry to age off.

You do not need to do anything special to remove the inquiry. It will age automatically and stop affecting your score after 12 months. Paying for credit repair services or disputing a legitimate inquiry is a waste of money.

Frequently Asked Questions

Does getting pre-approved at multiple banks hurt my score more?

No, if you do it within the rate-shopping window. Multiple mortgage inquiries in 14 to 45 days count as one inquiry for scoring purposes. However, inquiries from different types of lenders — a mortgage lender, a credit card company, and an auto lender — do not get bundled together and will each lower your score separately.

Will the pre-approval letter itself show up on my credit report?

No. Only the hard inquiry shows up on your report. The pre-approval letter is a document between you and the lender. It does not appear anywhere on your credit file, so it cannot lower your score beyond the initial inquiry.

Can I get pre-approved without a hard inquiry?

You can get a pre-qualification without one, but that is not the same as pre-approval. A pre-qualification is an estimate based on information you provide and uses a soft inquiry or no inquiry at all. A pre-approval is a commitment from the lender and requires a hard inquiry to verify your actual credit and income.

What if my score drops below my lender's minimum after pre-approval?

Contact your lender when ready. A small drop from the inquiry itself usually will not trigger a denial, but a larger drop from missed payments or new debt might. Your lender will re-check your credit before closing anyway, so it is better to address problems early than to be surprised at the final walkthrough.

How long does the pre-approval inquiry stay on my credit report?

The inquiry appears on your report for two years but stops affecting your score after 12 months. After 12 months, it is still visible to lenders who pull your full report, but credit scoring models ignore it. After two years, it disappears entirely.
