A single mortgage inquiry typically drops your credit score by fewer than five points. For most borrowers, the impact is minor and temporary, lasting only a few months before your score recovers. The bigger concern for many people is whether shopping around with multiple lenders will compound the damage, and the good news is that credit scoring models are designed to let you rate-shop without stacking penalties.
How Many Points You’ll Actually Lose
When a mortgage lender pulls your credit, it creates a hard inquiry on your report. Under FICO scoring, one hard inquiry costs fewer than five points for most people. VantageScore, the other major scoring model, tends to penalize slightly more, with a typical drop of five to 10 points per inquiry.
The exact hit depends on the rest of your credit profile. If you have a long credit history, low balances, and no recent missed payments, you’ll likely see a smaller dip. If your file is thin (meaning you have only a few accounts or a short history), a single inquiry can have a proportionally larger effect. Either way, a drop of under 10 points rarely changes a lender’s decision or pushes you into a worse interest rate tier.
Rate Shopping Counts as One Inquiry
Both major scoring models recognize that applying to several mortgage lenders in a short window is normal comparison shopping, not a sign of financial distress. They group multiple mortgage inquiries made within a set period and treat them as a single inquiry when calculating your score.
FICO uses a 45-day shopping window. As long as all your mortgage-related hard pulls fall within that span, they count as one inquiry for scoring purposes. VantageScore uses a shorter 14-day window for the same treatment. Since you won’t always know which model a lender is using, the safest approach is to do all your rate comparisons within two weeks. That way you’re covered under either model.
Keep in mind that every individual inquiry still appears on your credit report, even if the scoring formula groups them together. A lender reviewing your report manually can see each pull, but they understand what rate shopping looks like and won’t hold it against you.
How Long the Impact Lasts
Hard inquiries stay on your credit report for up to two years, but their effect on your score fades well before that. FICO only factors in hard inquiries from the previous 12 months, and VantageScore can consider them for up to 24 months. In practice, the actual numerical drag on your score usually disappears within a few months for both models.
This means that even if you see a small dip right after applying, your score will likely recover on its own as you continue making on-time payments and keeping balances low. By the time you close on the mortgage and settle into regular payments, the inquiry’s effect is negligible.
Which Steps Trigger a Hard Inquiry
Not every interaction with a mortgage lender dings your credit. The distinction comes down to whether the lender runs a full credit check or just a surface-level review.
- Prequalification: Some lenders base prequalification on self-reported information (your income, debts, and estimated credit score) without pulling your credit at all. Others do run a soft or hard inquiry even at this stage. Ask the lender before you proceed.
- Pre-approval: This step almost always involves a hard inquiry because the lender is verifying your financial details and issuing a letter you can use when making offers on homes.
- Final application: When you formally apply for the loan, the lender will pull your credit again if enough time has passed since the pre-approval check.
There is no universal rule that prequalification is always soft and pre-approval is always hard. Lender practices vary, so confirm with each one whether they’ll run a hard pull before you authorize it. If you’re just exploring your options early on, look for lenders that offer soft-pull prequalification so you can get a ballpark without any score impact.
Putting the Impact in Perspective
A mortgage inquiry is one of the smallest factors in your credit score. Payment history and the amount of debt you carry relative to your credit limits account for the vast majority of your score. A temporary dip of a few points from an inquiry pales in comparison to, say, a single late payment (which can drop your score by 60 to 100 points or more) or maxing out a credit card.
If you’re planning to apply for a mortgage, avoid opening new credit cards or taking out other loans in the weeks before and during the process. Those actions create additional hard inquiries outside the mortgage shopping window and can lower your score independently. The mortgage inquiries themselves, especially when grouped through smart rate shopping, are a minor and short-lived part of the process.
