When you apply to remortgage, your lender will look at your income and outgoings to see if you can afford the remortgage deal. If you don’t pass their checks, your application is likely to be refused. Like when applying for your initial mortgage, being refused a deal won’t, in itself, hurt your credit score. Your credit report will only show that you applied for a remortgage, but it won’t show whether you were accepted or not. However, being refused a mortgage can lead to more attempts to get one, and each application will leave a hard search on your report which will impact your credit score.
