Why Your Credit Score Matters for Mortgage Approval
Your credit score is one of three pillars lenders evaluate — alongside income and down payment. A higher score unlocks lower rates, smaller down payments, and access to more lenders.
| Credit Score Range | Rating | Mortgage Impact |
|---|
| 760+ | Excellent | Best rates, all lenders available |
| 680–759 | Good | Standard A-lender approval |
| 620–679 | Fair | Limited A-lender options, may need credit union |
| 500–619 | Poor | B-lender territory |
| Below 500 | Very poor | Private lender only |

| Consumer proposal | Severe | 3 years after completion |
| Bankruptcy | Severe | 6–7 years after discharge |
| Maxed credit cards (high utilization) | -30 to -70 points | Updates monthly |
| Too many credit applications | -5 to -10 per inquiry | 2 years (soft impact after 1) |

Tips for Getting Approved with Bad Credit
Increase Your Down Payment
A larger down payment reduces the lender’s risk and can offset a lower credit score.
| Down Payment | Effect on Approval Odds |
|---|
| 5% | Only A-lenders (680+ credit required) |
| 10% | Some credit unions may consider |
| 20% | B-lender approval likely |
| 25–30% | Strong B-lender approval; some private lenders at better rates |
| 35%+ | Private lender approval with best available private rates |
Use a Co-Signer
A co-signer with good credit can help you qualify for better rates. The co-signer is equally responsible for the mortgage if you default.
Work with a Mortgage Broker
A mortgage broker has access to dozens of lenders, including B-lenders and private lenders. They can match your profile to the right lender and negotiate on your behalf. For bad credit mortgages, a broker is almost always the best path.
Frequently Asked Questions
Can I get a CMHC-insured mortgage with bad credit?
No. CMHC, Sagen, and Canada Guaranty (the three mortgage insurers) require a minimum credit score of 600-680 depending on the insurer and the application. Without mortgage insurance, you need at least a 20% down payment.
Should I wait to improve my credit or buy now?
| Situation | Recommendation |
|---|
| Score is 600–679 | May be worth waiting 6–12 months to reach 680+ for A-lender rates |
| Score is 500–599 | Consider a B-lender now if housing costs are rising, plan to refinance in 1–3 years |
| Score is below 500 | Focus on credit rebuilding for 12–24 months unless you have 25%+ down |
| Housing market is cooling | Less urgency — use time to rebuild |
| Renting costs more than owning | Run the numbers with B-lender rates to see if buying still makes sense |
