If you’re like most homeowners, you probably believe that one missed mortgage payment won’t have a noticeable impact on your FICO score. People get behind now and then, and besides, you’ve been faithfully making payments on time for years. How bad could it be?

In truth, even one missed mortgage payment could seriously damage your FICO score. Lenders can report missed monthly payments whenever they choose – they don’t need to wait until a certain date to do it. That means even if your mortgage payment is a few days late, your lender may report it as unpaid.

So what exactly happens to a FICO score when you miss a mortgage payment? Here’s what you need to know.

Payment History: The Single Largest Factor In Determining Your Credit Score

FICO scores are calculated based on several different criteria, the largest of them being your payment history. A full 35% of your credit score is determined by how often you pay your bills on time and in full. And although FICO says that one or two late payments aren’t going to decimate your credit score, they will shave off some points that could have made the difference between a low-risk and high-risk interest rate.

Consumers With Higher Scores Have More To Lose

A 2011 FICO study analyzed the impact of late mortgage payments on consumer credit scores. The study grouped consumers into three groups based on their starting FICO score, with Consumer A having a score of 680, Consumer B a score of 720, and Consumer C a score of 780. The findings?

Even if you have a credit score of 780, being just 30 days late on a mortgage payment can result in a 100-point drop. And it can take up to three years to earn that credit back. In contrast, a consumer with a score of 680 who is 30 days late will see only a 70 point drop and can recover their original score within 9 months.

The takeaway? Contrary to popular belief, people with high credit scores stand to lose more from a missed payment than people with low credit scores.

There Are Varying Degrees Of “Late”

One common misconception is that if you miss a mortgage payment, it doesn’t matter if it’s 30, 60, or 90 days overdue. The mainstream thinking is that late is late is late. But that’s not how FICO sees it.

Although borrowers with credit scores under 700 won’t see much of a decline after 30 days late, borrowers with a higher credit score will. If you have a credit score of 720 and you’re 30 days late on your mortgage, your score will fall to about 640. If you’re 90 days late, that score will fall again this time, to about 620.

That means if you miss a mortgage payment, you need to get in touch with your lender as soon as possible in order make repayment arrangements and hope they haven’t yet reported the overdue payment. It’s your best shot at protecting your FICO score.

Credit scores can be vulnerable to all sorts of factors, which is why if you’re looking into mortgages, you’ll want to consult an expert. A qualified mortgage professional can help you find a mortgage you can afford, so your credit will stay intact. Contact your local mortgage expert to learn more.

One of the most significant factors a mortgage lender will review when you apply for a new mortgage loan is your credit history and rating. While some people have stellar credit, others have a troubled credit history with lower scores.

If you fall into the latter scenario, you may be wondering how lenders will assess your credit situation when you apply for a mortgage in the near future.

Reviewing Your Credit Scores

Initially, lenders will review your credit report to determine your credit scores. Your scores will have a direct impact on the interest rate that you qualify for or if you qualify for a loan at all. There are prime mortgages for good credit borrowers and sub-prime mortgages for those with a blemished credit rating.

If your scores are too low, however, you may not qualify for a mortgage. A mortgage representative can tell you more about their credit rating thresholds and the terms that you may qualify for.

High Debt Balances

Your mortgage lender will dig deeper into your credit report after an initial review of your credit rating. Your debt balances will be reviewed to determine your debt-to-income ratio. Provided your debt-to-income ratio and your credit rating are in line with requirements, high debt balances may not be an issue. Essentially, the lender will determine if you are able to make your payments on time as scheduled or if your debt balances appear to be burdensome. Even if your debt balances are high, you may be approved for a loan if you can afford to make the payments.

Difficulty Making Timely Payments

Your mortgage lender will also review the number of late payments on your credit report as well as the dates for those late payments. When late payments are clustered together, this may indicate a temporary rough patch rather than an on-going issue with making payments on time. However, if you have multiple payments that have been late over the course of the last year or two, this may indicate that you are not creditworthy as a loan applicant.

A credit report can tell a lender many things about you. While it superficially can tell a lender more about your outstanding debts, it also delves into previous financial issues and your overall responsibility with managing debt. If you have suffered from credit problems in the past, you may consider reaching out to a mortgage professional for more insight on how a lender will assess your credit situation.
