Buying a house when you're self-employed: mortgage, survey and timing

Being self-employed does not stop you buying a home, but lenders look harder at your income and the process can take a little longer. The fix is preparation: get your documents ready, use a broker who knows which lenders suit your income, and book your survey early so a slower mortgage does not leave you short of time.

Key points

  • Most lenders want two years of accounts or SA302s; some specialist lenders accept one.
  • Contractors, company directors and sole traders are assessed differently.
  • A broker who works with self-employed buyers can match you to the right lender first time.
  • Book your survey as soon as your offer is accepted, not after the mortgage offer.

What lenders want to see

  • Sole traders: usually two years of SA302 tax calculations and tax year overviews from HMRC.
  • Limited company directors: salary and dividends, and some lenders will also consider retained profit. This can make a big difference to how much you can borrow.
  • Contractors: some lenders work out income from your day rate and contract, which can suit people who have recently gone freelance.
  • Bank statements showing your income and outgoings, plus proof of deposit.

Rules vary widely between lenders, which is why going straight to your own bank can mean a lower figure or a decline.

Use a broker who knows self-employed cases

A specialist broker knows which lenders treat your type of income favourably and how to present your accounts. Option Finance in Derby helps self-employed buyers, company directors and contractors every week, alongside harder cases like adverse credit. Their first consultation is free.

Get your survey timing right

Self-employed applications can take a bit longer to underwrite. Do not let that push your survey to the end of the process. If the survey finds a problem late on, you lose your chance to renegotiate before exchange.

  1. Offer accepted.
  2. Instruct your conveyancer and submit your mortgage application.
  3. Book your survey the same week. A Level 2 Home Survey suits most conventional homes; choose a Level 3 for older or altered properties.
  4. Use the findings to renegotiate if needed while your mortgage completes underwriting.

Self-employed? Watch your cash flow on completion

If the lender's valuation comes in low or the lender imposes a retention, you may need extra cash on completion day. Self-employed buyers often have savings tied up in the business, so plan a buffer and talk to your broker and accountant early. See also what to do about a down valuation.

Your home may be repossessed if you do not keep up repayments on your mortgage. This guide is general information, not mortgage or tax advice.

Frequently asked questions

How many years' accounts do I need for a mortgage if I am self-employed?

Most lenders want two years of accounts or tax calculations (SA302s) with tax year overviews. Some specialist lenders will consider one year, usually with a larger deposit.

Do self-employed mortgages take longer?

Often a little, because underwriters check income more closely. Having your documents ready and using a broker who knows which lenders suit your income type helps a lot.

Should I wait for my mortgage offer before booking a survey?

Usually not. Book your survey soon after your offer is accepted so the findings arrive in time to renegotiate. If you are worried about the mortgage, ask your broker how confident they are before you spend the money.
