First-Time Buyer Deposit: How Much Do You Need?

26 March 20255 min read

Saving for a deposit is often the biggest hurdle for first-time buyers. The amount you need depends on the price of the property you want to buy and the loan-to-value (LTV) ratio you are comfortable with. This guide explains how much deposit you need, why a larger deposit helps, practical ways to save, and how family support can make homeownership achievable sooner.

How Much Deposit Do First-Time Buyers Need?

The minimum deposit accepted by most lenders is 5% of the purchase price. This means for a £250,000 property, you would need at least £12,500. For a £200,000 property, the minimum would be £10,000.

However, a 5% deposit puts you at 95% LTV, which means higher interest rates and fewer lender options. Reaching 10% (£25,000 on a £250,000 home) opens up a much wider range of deals at significantly better rates. The difference can be substantial — a 0.5% rate saving on a £200,000 mortgage could save you around £80 per month, or nearly £1,000 per year.

The best rates are typically available at 60% LTV, but for most first-time buyers the realistic targets are 5%, 10%, or 15%. Even moving from 5% to 10% can make a noticeable difference to your monthly payments and the total cost of your mortgage.

Tips for Saving Your Deposit

Building up a deposit takes time and discipline, but there are practical strategies that can help you get there faster:

  • Open a Lifetime ISA: Save up to £4,000 per year and receive a 25% government bonus of up to £1,000 annually. Over four years, that is £4,000 in free money towards your deposit. You must be aged 18–39 to open one.
  • Set a monthly savings target: Work out how much you need and by when, then set up a standing order to a dedicated savings account. Treat it like a bill that must be paid.
  • Review your spending: Track your expenses for a month and identify areas where you can cut back. Subscriptions, dining out, and impulse purchases are common areas where savings can be found.
  • Consider higher-interest savings accounts: Regular saver accounts often offer higher rates if you commit to saving a fixed amount each month. Shop around and make your savings work harder.
  • Reduce your rent: If possible, consider moving to a cheaper rental, sharing with flatmates, or living with family temporarily to accelerate your savings.

Family Help with Your Deposit

Many first-time buyers receive some form of financial help from family. There are several ways this can work:

  • Gifted deposit: A family member gives you money for your deposit as a gift, with no expectation of repayment. Most lenders accept gifted deposits from immediate family members, although they will require a signed letter confirming the gift is not a loan.
  • Family springboard or offset: Some lenders offer products where a family member places their savings into a linked account as security. The savings are returned (often with interest) after a set period, provided you keep up with your mortgage payments.
  • Joint borrower, sole proprietor: A scheme where a family member is on the mortgage (helping with affordability) but not on the property title. This means they help you qualify for a larger mortgage without being a legal owner of the property.

Guarantor Mortgages

A guarantor mortgage involves a family member (usually a parent) agreeing to cover your mortgage payments if you are unable to make them. The guarantor’s property or savings are used as additional security, which can help you borrow more or access a mortgage with a smaller deposit.

This is a significant commitment for the guarantor, as they become liable for your mortgage if you default. Both parties should seek independent legal advice before entering into a guarantor arrangement. Not all lenders offer guarantor products, so working with a broker is advisable to find the right option.

Watch out
A guarantor puts their own property or savings at risk. If you miss payments, the lender can pursue the guarantor for the debt. Both parties should get independent legal advice before committing.

Other Costs to Budget For

Your deposit is the biggest upfront cost, but it is not the only one. Make sure you also budget for:

  • Solicitor or conveyancer fees (£800–£1,500 plus disbursements)
  • Survey or homebuyer report (£250–£700)
  • Stamp duty (first-time buyers pay nothing on the first £300,000)
  • Moving costs (£300–£1,500 depending on distance and volume)
  • Furnishing and any immediate repairs or improvements
  • Buildings insurance (required by your lender from the date of exchange)

Frequently Asked Questions

Can I buy a house with no deposit?

Zero-deposit mortgages are extremely rare in the UK. The minimum deposit accepted by most lenders is 5% of the purchase price. However, some guarantor or family-assisted mortgage products effectively allow you to buy without a personal deposit, as a family member provides security or savings instead. These products carry specific risks and requirements, so professional advice is recommended.

Does a gifted deposit affect stamp duty relief?

No. Receiving a gifted deposit from a family member does not affect your eligibility for first-time buyer stamp duty relief. As long as you meet the definition of a first-time buyer and the property is within the qualifying price threshold, the relief applies regardless of where your deposit comes from.

How long does it take to save a deposit?

This varies enormously depending on your income, outgoings, and the property prices in your area. As a rough guide, saving £500 per month would give you a £12,000 deposit in two years, or £30,000 in five years. Using a Lifetime ISA adds up to £1,000 per year in government bonuses, which can significantly accelerate your timeline.

Can I use a personal loan for my deposit?

Most lenders do not accept borrowed funds as a deposit. They want to see that the deposit comes from genuine savings, a gift from a family member, or the sale of an asset. Using a personal loan would also increase your debt commitments, which could reduce the amount a lender is willing to offer you on a mortgage.
