Does Mortgage Pre-Approval Hurt Your Credit Score?

Mortgage pre-approval does not have to hurt your credit score. It depends on whether your lender uses a soft or hard credit inquiry. 

Here’s exactly what happens during pre-approval through closing, so you can move forward with confidence.

 

Does mortgage pre-approval hurt your credit score? 

Mortgage pre-approval will not hurt your credit score if your lender uses a soft credit check.

A soft inquiry lets a mortgage lender review your credit score and debts without affecting your score.

NewCastle uses a soft credit check when we pre-approve your mortgage. You can get pre-approved without lowering your credit score.

Other mortgage lenders may use a hard inquiry for pre-approval. A hard inquiry can temporarily reduce your credit score.

 

Ask the lender this question before getting pre-approved:

Will you use a soft or hard credit inquiry?

The answer matters, especially if you plan to start your home search months before buying.

A soft pull lets you get started without unnecessarily impacting your credit.

 

Example:

Sarah wants to buy a condo in Chicago. She expects her search to take several months.

NewCastle checks her credit with a soft inquiry and pre-approves her before she starts touring homes.

She knows she qualifies for a loan and her budget before shopping for a home. 

 

Get pre-approved with a soft credit check and know how much home you can afford. 

 

 

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:

 

1. Get Pre-Approved - Soft Credit Check

We use a soft inquiry that does not affect your score.  You get a  verified pre-approval letter.


2. Make an offer 

Use your verified pre-approval to strengthen your offer.


3. Go under contract - Hard credit check

Once the seller accepts your offer, we make a full credit check to process your final loan approval. 

 

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:

 

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:  

  1. Make  your  payments  on  time.  
  2. Keep your credit card balances low.   
  3. Avoid opening new credit cards.  
  4. Do not finance furniture before closing on a home.  
  5. 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. 

Get Pre-Approved and start your home search without affecting your credit score.
