How your credit score affects your mortgage

One of the most common topics customers ask me about is credit scores. “How will my credit score affect my rates? What if my partner or spouse has a low credit score? Will applying for a pre-approval hurt my score?” Here’s a roundup of the guidance I give them.

A higher credit score means more favorable rates

Basically, your credit score helps lenders evaluate your ability to pay back your loans, based on your borrowing history. The higher your credit score, the better rates you’ll be able to get, which can lead to significant savings over the life of your mortgage.

Note: Each of the three major credit bureaus (Transunion, Experian, Equifax) uses slightly different calculations to determine the credit score they give you. On top of that, each of those bureaus have several versions of credit scores. It can be a bit confusing, but at the end of the day the same basic factors affect all of your credit scores, so I encourage customers not to worry too much about each individual one.

Our basic pre-approval includes a soft credit check

Knowing your credit score helps us make make more accurate calculations. When you apply online for our 3-minute basic pre-approval, we’ll ask for your social security number and do a secure “soft” credit check, which doesn’t affect your credit score in any way (we use your FICO Classic 04 credit score from Transunion).

Reminder: Our basic pre-approval letter is great for people looking for a rough estimate of what they could be approved to borrow. It’s a good first step if you are just starting to think about shopping for a home or dropping by a few open houses. (Note: Not all pre-approvals are created equal, so if you’re working with another lender, ask.)

Our verified pre-approval requires a hard credit check

If you’re planning to make an offer on a home soon (especially in a competitive market), we encourage you to get our verified pre-approval letter. It’s more thorough than our basic letter and will give you an amount we’re confident we can lend to you. Our underwriting team will review documents like your tax returns, W2s, and paystubs to determine exactly how much you are qualified to borrow, helping your offer stand out by signaling certainty to the seller.

The verified pre-approval process requires a “hard” credit check (we use the median score from Transunion, Experian, and Equifax). This signifies to credit bureaus that you are interested in opening a new line of credit, and will have a small impact on your credit score (usually less than five points).

Frequently asked: how multiple credit checks work

The good news is that if you are shopping around with different lenders, credit bureaus will typically only dock your score once within a 30-day period, no matter how many mortgage lenders do a credit check. That means if you’ve already gotten pre-approved with another lender but want to switch to Better, getting a verified pre-approval or mortgage with us won’t impact your score again.

Keep in mind that even after you’ve been pre-approved, all lenders are required to do another hard credit check during the formal underwriting process, before they close your loan. So, if you don’t plan on applying for a mortgage within 30 days, we recommend getting a basic pre-approval for now (which doesn’t affect your score), and upgrading to a verified pre-approval once you’re ready to start shopping.

That said, I encourage borrowers not to sweat it too much if they do end up needing another hard credit check outside of the 30-day window. The impact to your credit score is relatively small.

Applying with a co-borrower

For our basic pre-approval, we do a soft credit check and use the lower of your two scores. For our verified pre-approval, we do a hard credit check from all three major credit bureaus and use the median of the three scores received, then use the lower score of the two borrowers.

Tip: If one co-borrower has a low credit score, we often recommend that the borrower with the higher credit score apply to get the best terms possible. You’ll still be able to put both names on the title. (Both borrowers may need to apply if more funds are needed for your down payment, or to improve your debt to income ratio).

How to improve your credit score

At Better, we can currently provide loans to customers with a credit score of 620 or above (given that other factors like debt to income ratio have been satisfied). If you have a lower credit score and a flexible timeline, you may want to wait and try and raise your credit score before applying, so you can qualify for better rates. On the other hand, if rates are low and you already have credit around or above 720, it may be more financially advantageous to take advantage of the low rates rather than waiting to raise your score.

Tip: If you’re still trying to determine your home buying timeline, you can use our rate tool to see how waiting and making improvements to your credit score could impact the price of your mortgage.
