Mortgages: How does a mortgage affect your credit score?

Mortgages: How does a mortgage affect your credit score?
Share

Your credit rating can be a determining factor in whether or not you are approved for a mortgage. Few people can afford tobuy a property entirely with cash, so your credit score will help the lender determine the risk you represent as a potential customer. However, it’s not just the credit score you have before you take out a mortgage that matters. The mortgage itself can have a significant impact on your credit rating. Assuming you make all your payments on time, as agreed to in the terms of your mortgage, your mortgage is likely to give your credit rating a big boost.

Credit history improvement

Credit history is one of the most important determinants of your credit rating and viability as a lender. Nothing has more impact on your credit rating than the history of payments you’ve made against borrowed money. Your typical mortgage will likely have an amortization period of 15 to 30 years, which means you will have to make many credit-related payments during that time. If all your payments are made on time during this period, it can really improve your credit score. Another factor is the age of your credit. It will help if you show that you can pay your mortgage consistently over a long period of time. It should be noted, however, that missed payments can hurt your credit score, even if it’s just one missed payment. One missed payment can ruin the benefits of 30 years of regular payments you have made.

Diversified credit

Another factor in your credit score is the number of different types of credit you’ve had over the course of your credit history. There are many different credit applications you can make, from credit cards, to auto loans, to mortgages, etc. Having a wide variety of these types of loans can improve your credit score. However, even with the most diverse credit history possible, you can’t make up for a history of missed payments. These types of loans are considered different types of credit, from the credit card which is a revolving credit loan, and the mortgage which is an installment loan. Having these different types of loans shows the diversity of credit repayment regardless of the configuration.

The difference between a mortgage and rent

The main difference between a mortgage and rent when it comes to your credit score is that rent payments are not a form of credit. In this case, the owner of the property does not lend you anything on which you make repayments. Renting is essentially a service at its core. You pay someone for the service of living on their property. A mortgage, on the other hand, involves receiving a lump sum of money to invest in a property that you will purchase, and then paying off that loan, thereby improving your credit rating (assuming payments are made on time). Rents can be factored into a credit scoring model, but must be reported through rental reporting services. However, it’s not that common, and unlike a mortgage that will automatically be reported to the credit bureaus, incorporating rental history into your credit score is not a simple process.

Negative impact of a mortgage

As we’ve seen, a mortgage will help you build credit over time if you make your payments on time. However, taking out a mortgage can also lower your credit rating at the beginning. When you decide to apply for your mortgage, the lender you choose will perform a credit check to read your dossier de crédit and determine if you can be approved. The credit report will trigger what is called a « credit impact inquiry ». Running this report can temporarily lower your credit score by a few points. It is important not to apply for too much credit in a short period of time, as all lenders will be looking at this report and it could negatively impact your credit history. However, FICO, which produces the credit scores, has a system in place that does not take into account multiple applications within a 45-day period, so multiple mortgage applications should not have a significant impact on your credit score. The standard approach to these credit reports is for the lender to take reports from the three major credit bureaus. They will then take the average of the three scores or choose the median score to determine whether or not they will accept you and what rate they will offer you. If you choose to view your dossier de crédit (which is free), you will be able to see the history of inquiries made by lenders over time. The bottom line is that taking out a mortgage with your lender can have a temporary negative impact on your credit score until you can prove your ability to repay the loan. To consistently improve your credit rating, you must make regular and timely payments throughout the life of your mortgage. In addition, your mortgage will contribute to your credit rating by improving the composition of the various debts you have incurred. As long as you make your mortgage payments on time, you will reap the benefits of a mortgage in the eyes of the credit bureaus. If you miss a payment, there are credit repair companies that can advise you on the best course of action.

So you can apply with confidence.*Instant decisions are only available for consumer Card applications (also called “personal Cards”).

The Marriott Bonvoy® American Express®* Card is the best credit card in Canada for free hotel nights.

New Cardmembers can earn up to 110,000 Marriott Bonvoy® points with the current offer:

  • Earn 80,000 points after you spend $6,000 on your Card in your first 6 months of Cardmembership.
  • Plus, earn 30,000 points by making a purchase during your 15th month of Cardmembership.

This offer ends on September 22, 2026. The annual fee is $120, and there is no annual fee on Additional Cards, so you can add a partner or a family member at no extra cost.

Every year after your first Card anniversary, you receive an Annual Free Night Award good for a redemption of up to 35,000 points at eligible hotels and resorts worldwide. At a valuation of 0.9 cents per Marriott Bonvoy point, that certificate is worth roughly $315, which on its own more than covers the $120 annual fee. That is the main reason to keep this Card year after year instead of cancelling it.

To get the most out of the certificate, aim it at a night that would otherwise price close to the 35,000 point ceiling.

The Card also gives you 15 Elite Night Credits each calendar year and automatic Marriott Bonvoy Silver Elite status. Those credits count toward the next Elite tier, so you begin every year 15 nights ahead of where you would otherwise start.

You move up to Gold Elite status automatically when you reach $30,000 in purchases on the Card in a year, or when you combine 10 qualifying paid nights within one calendar year with the 15 Elite Night Credits from your Card.

Marriott Bonvoy points are generally valued at 0.9 cents each. On that basis, the 110,000 point welcome offer is worth about $990, and an Annual Free Night Award used at its full 35,000 point ceiling is worth about $315.

Marriott Bonvoy points pull their weight on free nights rather than on gift cards or merchandise, which is why this Card should be judged on the hotel stays it produces.

You earn 5 points per dollar on eligible purchases at participating Marriott Bonvoy hotels and 2 points per dollar on all other purchases. Points can be redeemed for free nights with no blackout dates at more than 7,000 hotels around the world.

The Card carries a solid package of coverages: $500,000 travel accident insurance, flight delay, baggage delay, lost or stolen baggage and hotel or motel burglary at $500 each, car rental theft and damage up to $85,000 for rentals of up to 48 days, Purchase Protection for 90 days and a one year Extended Warranty.

Two things to plan around: the 2.5% foreign transaction fee on purchases made in a foreign currency, and the 21.99% purchase interest rate, which makes this a Card to pay in full every month. Like all American Express Canada Cards, no minimum income is published for this Card, and you can see whether you would be approved before you apply, with no impact on your credit score.
