Self-employed mortgages and the income lenders assess

A successful business does not always produce a straightforward mortgage application. Turnover, taxable profit, salary and dividends are different figures, and lenders may use different evidence to decide which income they can accept.

If you are self employed or a company director, the first step is to establish how your business is structured and which figures explain your earnings accurately. That helps avoid a borrowing estimate based on money the lender cannot use.

Turnover is not your personal income

Turnover measures business sales before the relevant costs are deducted. A lender assessing a sole trader generally needs evidence of profit rather than treating all sales as income available for mortgage payments.

For a partnership, your share of the business earnings matters. For a limited company director, a lender may consider salary and dividends; some criteria allow a salary and share of company profit approach. Shareholding, sustainability and the lender's definition of the profit figure all need checking. The balance in a business account is not automatically additional personal income.

The trading history helps explain the figures

Lenders can have different requirements for the number of completed trading years and how they treat a changing income pattern. An average of earlier years may give a different result from the latest year's earnings.

Increasing income does not mean every lender will use the highest figure.

Explain significant changes, such as a new contract, a one-off expense or a move from sole trader to company.

Provide evidence rather than assuming the change will be disregarded. If the business has had a weaker period, address that directly and explain the current position accurately.

Build a consistent document pack

Depending on your structure and the lender, you may need:

• Completed business accounts.

• HMRC tax calculations, often called SA302s, and tax year overviews.

• Personal and business bank statements.

• Evidence of salary and dividends for company directors.

• Accountant details and clarification of unusual items where requested.

• Deposit evidence and details of existing commitments.

A tax calculation and a tax year overview serve different purposes. Make sure the documents relate to the requested years and that names, figures and dates are consistent. Ask your accountant for the correct records if something does not reconcile.

Think about the application and the business together

Do not change how you take income solely because you assume it will improve mortgage borrowing. Dividends and salary decisions have accounting and tax consequences and should be discussed with your accountant.

Likewise, distinguish genuine recurring earnings from one-off receipts. Your adviser can investigate which assessment may fit the business, but neither a projected result nor an accountant's letter guarantees that a lender will accept a particular amount.

Your outgoings remain part of affordability

The lender also assesses household commitments and the proposed mortgage. A strong profit figure does not remove the effect of debts, childcare, other property commitments or the size of the deposit.

Before applying, prepare a realistic household budget and tell your adviser about planned changes. Explain whether business borrowing affects your own commitments or whether you have given relevant guarantees.

Start with the evidence rather than a salary multiple

An online multiple of annual income is only an initial illustration. For self employed applicants, the important question is which income the lender will accept and how that fits its affordability calculation.
