After making your initial enquiry the first step in the mortgage application process is to make contact a lender. If you have made your enquiry through an Independent Financial Adviser (IFA), they will usually do this for you. The lender will then request a credit test and income review to assess the mortgage affordability requirements and terms. After the initial assessment a decision in principle will then be given to the applicant by the lender. If the decision in principle is acceptance the applicant will then be required to make a full mortgage application and provide all supporting documentation requested.
