Your credit score won't be affected by simply marrying someone with good or bad credit, but there are scenarios where their credit behavior can affect your credit score and your ability to get a mortgage.
Tying the knot often means tying your finances to your spouse's. And while there isn't a direct link between your spouse's credit score and your credit score -- you won't have bad credit just because your spouse does -- there are some cases where bad credit management by one spouse can negatively affect the credit score of the other spouse.
Below, I'll explain the ins and outs of credit scores, ways in which your spouse's credit can affect yours, and how your spouse's credit can affect your personal finances in ways beyond just your credit score.
The way to think about credit scores is that they are a "grade" based on the information in your credit report. Credit scoring companies look at what's on your credit report, and based on that information -- your payment history, your existing balances, credit mix, and so on -- they calculate a numerical value. A FICO® Score can range from 300 to 850, with higher numbers being better.
Here's a quick guide to the five parts of your credit score:
Credit scores are ultimately designed to measure the risk that you will fail to make payments on time or at all, and it's something credit scores do really well. All else equal, someone with a 750 credit score is much less likely to default on a loan than someone with a 600 credit score.
Your spouse's ability to manage his or her credit can affect your credit score, but only if you have shared accounts in one way or another. For example, many couples have credit cards, car loans, or mortgages on which they are joint borrowers, meaning they are both responsible for making payments.
If you have a joint credit account with your spouse, and he or she fails to make on-time payments, the late payments will appear on both of your credit reports. Naturally, these late payments would also harm both of your credit scores.
Even if you aren't late on a bill, a joint account can still hurt your credit score if it isn't optimally managed. For example, you and your spouse might be jointly responsible for a credit card account with a $5,000 limit. If from month to month you carry a balance of $3,000 on it, you'll have used 60% of available credit on the account, which negatively affects your credit score. Ideally, balances shouldn't be higher than 30% of the credit limit at any point in time.
Finally, your spouse's credit can also affect your credit if you are an authorized user on their credit cards. When you are an authorized user on someone else's credit account, all of the history associated with that account is imported into your credit report. If they failed to make on-time payments in the past, or keep high balances on that account, it could negatively affect your credit report and score.
Luckily, you can easily remove a spouse as an authorized user on a credit card account. We've also seen data points that suggest the authorized user can request a deletion of the record from their credit reports with relatively high success. Unfortunately, this "trick" does not apply to accounts where you are joint borrowers, however. A joint borrower is legally responsible for paying on any balances whereas an authorized user has no such responsibility.
Even if your spouse's credit behavior doesn't directly affect your credit score because you don't have shared accounts, it can affect you in other ways, particularly when it comes to borrowing large amounts of money to buy homes or cars.
Your spouse's credit matters a lot when it comes time to buy a home. That's because many married couples buy a home based on what they can afford with their combined incomes. However, if one person has bad credit, applying together to get the benefit of both incomes may not outweigh the downside of having the lender look at both spouses' credit scores.
Here's how this works: Lenders use what's known as the "lower middle score" rule for large loans like mortgages. A lender looks at all three credit scores of each applicant, and uses the lower of the middle scores to determine how to price the loan, and whether to go through with the loan in the first place.
It sounds more complicated than it is. Here's an example to set it all straight.
Let's suppose Sally and Frank are married and want to buy a home together, and their credit scores are as follows:
We first need to find the middle score for each applicant. Sally has excellent credit scores, with a middle score of 801. Frank's middle score is 689. Lenders will use the lower of these two middle scores to determine the rate and terms for the mortgage. In this case, Frank's middle score of 689 would be the one they use.
This can be a big problem for some couples. On one hand, applying together allows Sally and Frank to leverage their combined incomes on an application. Two incomes is almost always better than one, so being able to put down their combined income on an application should theoretically allow them to borrow more money.
On the other hand, because Sally and Frank are applying together, Frank's bad credit will weigh heavily on their application. In this scenario, the best possible move -- if Sally's income is high enough to qualify on her own -- is to have Sally apply individually and leave Frank off the loan.
You can see where this might be a problem. Many couples have to carefully weigh whether it makes sense to apply jointly, and thus use both of their incomes on an application, or have only one person apply for the mortgage because of one spouse's bad credit.
Assuming Sally and Frank each earn $75,000 per year, it all boils down to whether a $75,000 income and an 801 FICO® Score is better than $150,000 in combined income and a 689 credit score. Some banks or mortgage programs may prefer the higher income and lower score, whereas other banks and mortgage programs may favor the lower income applicant with a higher credit score.
