If you were denied a loan due to past credit issues, there may be some lenders that could still accept your application. Some lenders will underwrite (assess) each application on a case by case basis with no computer or hard credit search being the reason you get declined.
We highly recommend that you speak with an independent mortgage adviser to discuss the options available to you. Dashly works with independent mortgage advisors and you can book an appointment to speak to them through your dashboard.
