First-Time Buyer Mortgages in the UK
Buying your first home is one of the biggest financial steps you’ll take. This guide covers what UK lenders look at, the deposit options available, and the schemes that may help.
Your home may be repossessed if you do not keep up repayments on your mortgage.
This page is for buyers preparing for a first residential mortgage in the UK.
Quick summary
- Most lenders need a minimum 5% deposit, but 10–15% unlocks much better rates.
- Government-backed options include the Mortgage Guarantee Scheme and the Lifetime ISA.
- Affordability assessments are typically 4× to 4.75× combined income, less commitments.
- A credit footprint of 3–6 months helps — being on the electoral roll, settled at one address, etc.
- A mortgage agreement in principle (AIP) is usually required before estate agents take offers seriously.
What lenders may look at
- Combined income
- Deposit size and source (savings, gift, LISA)
- Credit history and active commitments
- Employment stability
- Property type and construction
Documents you may need

- 3 months of bank statements
- Latest 3 months payslips (employed)
- 2 years SA302s + tax year overviews (self-employed)

Practical next steps
- Estimate an affordable price range before viewing properties.
- Check that deposit funds can be evidenced and any gifted deposit is documented.
- Review credit files and regular commitments before a lender application.
- Consider an agreement in principle once your budget and documents are ready.
Common issues
- Deposit smaller than 10% — many lenders cap LTV at 90% on flats, ex-local-authority and new build.
- Recent job change inside probation — most lenders prefer 3+ months past probation.
- Thin credit file — start building one well before applying.
- Spending patterns showing payday loans or persistent overdraft — lenders look at the last 3 months of bank statements.
