How Much Deposit Do You Really Need for a First-Time Buyer Mortgage in 2025?

Saving for a deposit is one of the biggest hurdles for first-time buyers. But how much do you actually need in 2025? Let’s break it down.

Minimum Deposit Requirements

In 2025, most lenders require a minimum deposit of 5%. However, your options improve with a 10% or 20% deposit.

  • 5% deposit: Limited mortgage choices, often with higher interest rates.
  • 10% deposit: More mortgage deals, better interest rates.
  • 20% deposit: Access to the lowest rates and lower monthly repayments.

For example:
If you want to buy a £250,000 home:

  • 5% deposit = £12,500
  • 10% deposit = £25,000
  • 20% deposit = £50,000

How to Save for a Deposit Faster

  • Open a Lifetime ISA (LISA) – Get a 25% government bonus on savings.
  • Cut back on expenses – Reduce rent, subscriptions, and unnecessary spending.
  • Check first-time buyer schemes to see if you can buy with a lower deposit.

💡 Tip: A larger deposit reduces your loan-to-value (LTV) ratio, making you a lower-risk borrower and securing better mortgage deals.
