One of the biggest myths in mortgage lending is that checking your credit or shopping for a mortgage will dramatically lower your credit score. Fortunately, that’s generally not how mortgage credit scoring works.
Understanding how inquiries work can help you shop for the best loan without unnecessary concern.
What Is a Credit Inquiry?
A hard inquiry occurs when a lender accesses your credit report as part of a credit application.
Examples include:
- Mortgage applications
- Auto loans
- Credit cards
- Personal loans
Hard inquiries differ from soft inquiries, which occur when you check your own credit, receive a pre-approved offer, or when your lender performs a soft credit review before closing. Soft inquiries typically do not affect your credit score.
How Do Inquiries Affect My FICO® Score?
For most consumers, a single hard inquiry has only a small impact, often just a few points, although the exact effect depends on your overall credit profile.
FICO recognizes that consumers should be able to compare lenders before making a financial decision.
Because of this, mortgage inquiries made within a designated shopping window are generally treated as one inquiry for scoring purposes rather than several.
Depending on the FICO model used, the shopping window can range from 14 to 30 days. Since mortgage lenders use several different mortgage-specific FICO models, it’s wise to complete your rate shopping within a short period after the first mortgage inquiry.
Once that shopping period has passed, additional hard inquiries may affect your score individually. Typically, the initial inquiry or those outside the shopping-window typically impact credit for 90 days.
What Are Trigger Leads?
When a mortgage lender pulls your credit, the credit bureaus have historically been permitted to sell limited inquiry information to other lenders. This practice, known as trigger leads, often resulted in borrowers receiving unsolicited calls, emails, and mail from competing lenders shortly after applying for a mortgage. Sometimes 10-100 calls over 90 days – annoying!
Recent federal legislation has significantly restricted the use of trigger leads for mortgage transactions, with implementation occurring through updated regulatory requirements. The goal is to better protect consumers from unwanted solicitations after applying for a home loan. Your privacy protection is first and foremost.
Why Does My Lender Ask About Credit Inquiries?
During underwriting, lenders review all recent credit inquiries.
If new inquiries appear after your initial application, your loan officer may ask you to complete an inquiry explanation letter.
The purpose isn’t the inquiry itself.
The underwriter wants to determine whether the inquiry resulted in new debt.
What Is the Underwriter Looking For?
Common questions include:
- Did you finance a new vehicle?
- Did you open a new credit card?
- Did you purchase furniture or appliances for your new home?
- Did you obtain a personal loan?
- Did you purchase another property?
If the answer is no, a simple written explanation is often sufficient.
If new debt was opened, the lender must determine whether it affects your debt-to-income ratio or your ability to qualify.
The Soft Credit Pull Before Closing
Many lenders perform a soft credit pull shortly before closing.
This final review doesn’t generate another hard inquiry and typically doesn’t impact your credit score.
Instead, it confirms that no significant financial changes have occurred since the original application.
The lender is looking for new obligations such as:
- Auto loans
- Credit cards
- Personal loans
- Another mortgage
- Large financed purchases, including furniture or appliances
If new debt appears, the underwriter may need to recalculate your qualifications before authorizing the loan to close.
Final Thoughts
Credit inquiries themselves rarely prevent someone from qualifying for a mortgage. What matters is whether those inquiries resulted in new debt that changes your financial profile.
Once you’ve applied for a mortgage, try to avoid opening new credit until after your loan funds. If you’re considering financing a vehicle, purchasing furniture, or applying for additional credit, talk with your mortgage professional first. A quick conversation can help ensure your financing stays on track and your home purchase in the Temecula Valley closes without unexpected delays and avoids a last minute financial grenade.
