Many Credit Applications. Each time you make a credit application, it is documented on your credit report and if you do multiple applications within a short period, then it will be seen as a red flag in your mortgage application.
Reasons Your Mortgage Application May Be Rejected
Financial History. Before making a mortgage application, or applying for any significant loan, it is always best to review your existing credit report.
Something as minute as the wrong home number on the address, or other trivial but important details can prevent your approval.

If you spend six months bettering your credit score before making a mortgage application, it will increase the likelihood of your application getting approved.
