What is a self certified mortgage?

As working practices have changed over the years, more and more people are unable to produce traditional financial data to confirm their income. This can lead to problems when trying to arrange loans and mortgages. However, self certified mortgages are tailor made for people who are unable or unwilling to prove their income. It’s a popular choice for all kinds of borrowers, including freelancers, unsalaried company directors, part-time employees and even people with bad credit history. Most lenders will only ask you to sign a declaration agreeing that you can afford the loan repayments, however, as advisors it will be necessary for us to assess affordability and to do so we will ask you to provide reasonable evidence of your earnings.

PLEASE NOTE: Although the Lender may not require evidence of income, we will require evidence so that we can establish affordability of the mortgage. We will not give advice or process a loan where we cannot evidence sufficient income to meet the mortgage commitments.

Using the self certified calculator

Simply type in the amount you want to borrow and our self certified mortgage calculator will give you an idea of how much your monthly repayments will be. Before you sign up to any deal, it’s worth considering the following points:

- Accounts, payslips and statements are not required to be approved

- You can arrange a self certified deal at any interest rate type that you would find with traditional mortgages, including fixed, capped, tracker and discount

- Suits a broad range of borrowers, including people on multiple incomes, part-time employees, bonus-reliant income, people who receive much of their income from shares and investments, contractors, and freelancers

- If your current income doesn’t reflect what you expect to earn in the near future, you can self-certify to take that into account

- Due to extra risk for the lender, self certification usually has higher interest rates than traditional mortgages

- Usually requires a larger deposit than standard mortgages (generally, the higher the deposit, the better the interest rates)
