Does Refinancing Affect Your Credit Score?
Yes, slightly. When you formally apply for a new home loan, the lender checks your credit file and that check is recorded as an enquiry. One enquiry for a home loan, from a borrower with a clean repayment history, usually moves a score only a little, and its influence fades as time passes. Lenders reviewing a home loan application expect to see it.
How Long Does a Credit Enquiry Stay on Your File?
In Australia a credit enquiry remains on your credit report for five years. Its weight in scoring models is greatest when it is recent. Your file also shows up to 24 months of repayment history on loans and credit cards, month by month, and that history generally matters more to a lender than a single enquiry.
What Actually Hurts Your Credit Score When Refinancing?
- Multiple applications in a short time. Applying to several lenders to see who approves leaves several enquiries, which can read as credit stress.
- A declined application followed by further applications elsewhere.
- A missed repayment during the switch. Keep paying the old loan until you have confirmation it is closed. A direct debit cancelled a week early can leave a late mark that stays visible for two years.
- New debts taken on around the same time, such as car finance or a new credit card.
The enquiry is not the risk. The risk is applying in the wrong place. Before anything is lodged I check your scenario against lender policy, which does not touch your credit file, and I can see a copy of your credit report with your consent so there are no surprises. Then one application goes to the lender it fits. One enquiry, one approval, and your file looks the way a lender wants it to look.
Does Comparing Rates Affect Your Credit Score?
No. Researching rates, using calculators, having a broker compare lenders and requesting a reprice from your existing lender do not create credit enquiries. Only a formal credit application does. Checking your own credit report does not affect your score either, and you are entitled to a free copy from each credit reporting body.
Can Refinancing Improve Your Credit Position?
Indirectly, it can. A lower repayment is easier to meet on time, and a record of on-time repayments is the strongest positive on a credit file. Refinancing to consolidate several debts into one can also reduce the number of open accounts and the chance of missing one, provided the consolidated debts are closed and not run up again. See debt consolidation home loans.
Will Lenders Decline You for Refinancing Too Often?
Refinancing every few years is normal and lenders do not penalise it. Several home loan applications within a few months is different, and a new lender may ask why. If you have a reason, such as a purchase that fell through, it can be explained in the application.
What If Your Credit File Already Has Problems?
Late payments, defaults or a high number of enquiries narrow the choice of lenders but do not necessarily end it. Specialist lenders price for these situations, and a clean period of repayments can open the mainstream lenders again later. That path is covered in refinancing with bad credit.
How Do You Protect Your Score During a Refinance?
- Have your scenario checked against lender policy before applying.
- Lodge one application, with the lender most likely to approve it.
- Keep every existing repayment running until settlement is confirmed.
- Avoid new credit applications from a few months before applying until after settlement.
- Close unused credit cards you do not need, which also helps serviceability.
