Build credit with zero rejections

Building credit to buy a house in Canada can take anywhere from several months to a few years.

If you're starting with no credit history, you may begin establishing credit within six months.

If you have missed payments, collections or significant debt, improving your credit could take longer. Your timeline depends on your starting point and how consistently you manage credit.

KOHO Credit Builder

KOHO Credit Builder helps Canadians establish or improve their credit history through consistent monthly payments, without relying on a traditional credit card.

With KOHO Credit Builder, you can:

  • See an average credit score increase of 74 points*

  • Get approved without a hard credit check or minimum deposit

  • Pay no interest on the line of credit

  • Track your credit score and credit report directly in the KOHO app

  • Build credit history through monthly payments reported to the credit bureaus

What Credit Score Do You Need to Buy a House?

Many traditional mortgage lenders prefer a credit score of 680 or higher.

For CMHC insured mortgages, at least one borrower or guarantor generally needs a credit score of 600 or higher. Individual lenders may have stricter requirements.

A higher score may give you access to more mortgage options and competitive rates, but it doesn't guarantee approval.

How Long Does It Take to Build Credit From Scratch?

If you've never had a credit card or loan, establishing a credit history may take approximately three to six months.

However, having a credit score is not the same as having enough credit history to qualify for a mortgage.

Lenders may prefer to see a longer record of responsible borrowing. Building six to twelve months of positive payment history can be a useful starting point, but some lenders may expect more.

How Long Does It Take to Rebuild Bad Credit?

It depends on what's affecting your score.

  • High credit card balances: Your score may improve relatively quickly after you pay them down and the new balances are reported.

  • Missed payments: Rebuilding a positive payment history can take several months or longer.

  • Collections or bankruptcy: Recovery can take years because negative information may remain on your credit report for an extended period.

There is no guaranteed timeline or number of points you can expect to gain.

How Can You Build Credit Faster Before Buying a House?

Focus on the factors you can control.

  1. Pay every bill on time. Payment history is one of the most important factors affecting your credit score.

  2. Keep credit utilization low. Aim to use less than 30% of your available credit.

  3. Avoid unnecessary credit applications. Multiple hard inquiries can temporarily affect your score.

  4. Review your credit reports. Check Equifax and TransUnion for errors that could be hurting your credit.

  5. Keep older accounts in good standing. A longer history of responsible credit use can strengthen your credit profile.

You don't need to carry a credit card balance or pay interest to build credit.

Can You Get a Mortgage With Limited Credit History?

Possibly.

Some lenders and mortgage insurance programs may consider alternative evidence of creditworthiness, particularly for newcomers or people who have not used traditional credit products.

This could include rental payment records, utility payment history or other financial information, depending on the lender.

A mortgage broker may help you understand which lenders consider applicants with limited credit history.

Should You Wait Until Your Credit Score Improves Before Buying?

If your score is below a lender's requirements, taking time to improve it could help you qualify for more mortgage options.

However, credit isn't the only consideration. Lenders also review your income, existing debt, down payment and ability to afford mortgage payments.

Before applying, check your credit reports, reduce outstanding debt and speak with a lender about your eligibility.
