Build a clear income record
- Keep completed accounts or tax-return information together where available.
- Keep an orderly record of sales, income and business expenses so figures can be checked against supporting evidence.
- Label completed periods separately from the current year so it is clear what is historical and what is still in progress.
Keep your supporting records easy to review
- Save sales invoices, receipts, supplier invoices and bank statements with the related records.
- Make sure transactions can be identified as business transactions and investigate unclear entries before relying on a summary.
- Keep records readable and organised rather than rebuilding them under time pressure.
Prepare deposit and property information
- Record the source of any deposit and keep supporting evidence available for discussion.
- Write down the property budget and the assumptions behind it, but keep this separate from any lender decision.
- Avoid presenting projected income as completed evidence; mark it clearly as a current-year forecast if you discuss it.
Speak with an adviser when you are ready
- A lender or mortgage adviser may ask for accounts or tax returns when you are self-employed, but their requirements and affordability checks vary.
- Ask an FCA-authorised mortgage adviser or lender which documents are relevant to your circumstances.
- Use Mortgage Readiness to organise the preparation process; it does not assess creditworthiness, select a lender or guarantee an outcome.
