Does mortgage pre-approval hurt your credit score?
Contents
Is mortgage pre-approval a hard or soft credit check?
A mortgage pre-approval can use either a soft or hard credit check. The lender decides which type to use.
A soft inquiry reviews your credit without lowering your score. A hard inquiry becomes part of your credit history and may affect your score.
Here is how NewCastle handles credit:
| Stage | Credit Check | Effect on Score |
| Check mortgage rates | None | No impact |
| Get pre-approved | Soft inquiry | No impact |
| Shop other lenders | Hard inquiry | May cause a small drop |
| What it shows | Hard inquiry | Generally grouped when completed within the shopping window |
We use a soft inquiry to evaluate your credit during pre-approval.
That gives us the information needed to review your debts, credit history, and mortgage options.
We can then issue a verified mortgage pre-approval without lowering your credit score.
Once you find a home, your loan moves from home shopping to mortgage underwriting. That is when we obtain the full mortgage credit report.
When does NewCastle Home Loans make a hard credit inquiry?
NewCastle Home Loans makes a hard credit inquiry after you have an accepted purchase contract and move forward with your mortgage.
We do not make a hard inquiry just because you want to check rates or get pre-approved.
Here is the typical process:
Example:
Sarah followed this process. She was pre-approved in March but did not find her condo until May.
NewCastle waited until May to make the hard inquiry.
She avoided using a hard credit inquiry months before she actually needed the mortgage.
What is the 45-day mortgage shopping window?
The 45-day mortgage shopping window allows multiple hard credit checks to count as one inquiry.
This mortgage shopping window lets you compare lenders without every mortgage inquiry counting separately against your credit score.
Mortgage scoring models recognize that you are shopping for one mortgage, not trying to open several unrelated accounts.
Example:
Sarah went under contract on May 5.
NewCastle checked her credit and sent an official Loan Estimate.
She compared another lender that week to make sure she was getting the best deal.
Why do mortgage lenders need a full credit check?
Mortgage lenders use a full credit check to verify your credit score, debts, and payment history.
This information helps determine your loan eligibility, interest rate, and monthly payment.
At NewCastle, we use a soft credit check for mortgage pre-approval. We make the hard credit inquiry after you are under contract and ready to move forward with your mortgage.
A full mortgage credit report typically includes information from TransUnion, Equifax, and Experian. It shows your credit scores, account balances, monthly payments, and payment history.
Your credit matters because it can affect:
- Your mortgage interest rate
- Your loan eligibility
- Your mortgage insurance
- How much you can borrow
- Your monthly payment
Once you have a property address, you can also request an official Loan Estimate.
A Loan Estimate is a standardized three-page disclosure. It shows the proposed interest rate, payment, lender fees, closing costs, and cash to close.
How can you protect your credit after mortgage pre-approval?
Keep your finances steady after pre-approval and avoid taking on new debt before closing.
Your lender will review your financial condition during the mortgage process. Changes can affect your approval even if your original pre-approval used a soft inquiry.
Follow these simple steps to improve your credit score:
- Make your payments on time.
- Keep your credit card balances low.
- Avoid opening new credit cards.
- Do not finance furniture before closing on a home.
- Steer clear of new auto or personal loans.
For example, charging furniture or other large purchases can increase your credit utilization and lower your credit score. Additionally, taking on new debt can raise your debt-to-income ratio.
NewCastle starts with a soft credit check. You can learn your buying power and receive a verified pre-approval without lowering your score.
Once you find your home, we guide you through the hard credit check, mortgage comparison, and final approval.
