It's tough to definitively state what the cut-off point is for getting home loan approval, as banks and lenders consider their own internal credit assessments along with your score when reviewing your application.
However, credit score providers like Experian do have benchmarks that can be useful in getting an idea of how likely you are to be approved for a home loan. Below is a guide of how your credit score could influence your home loan approval odds with Experian, who run their credit scores between 0 and 1000. The higher the number, the better your credit score is.
Excellent: A score between 800-1,000 is considered Excellent. This means the bank view you as being extremely low risk of defaulting on your loan. If your score is in this range, home loan approval is likely.
Very Good: A score from 700-799 is considered Very Good and puts you in the second-top tier of creditworthiness. Most lenders would look very favourably on your application.
Good: A score from 625-699 is classified as Good. This still puts you in good standing and the bank views the likelihood of an "adverse event" occurring on your credit file in the next 12 months to be low.
Fair: A score from 550-624 puts you in the Fair category. This means you're more likely to suffer an adverse event on your credit file in the next 12 months, so lenders may apply additional loan criteria or charge you a higher rate.
Weak: Any score below 549 puts you in the Weak category. Lenders consider the likelihood of an adverse credit event high. You may have trouble obtaining finance from traditional lenders.
