How Much Deposit Do I Need to Buy a House in Wales?

If you are thinking about buying a home, one of the first questions you are likely to ask is: how much deposit do I actually need?

It is easy to assume that you need a huge amount saved before you can even speak to a mortgage adviser. In reality, some buyers may be able to purchase with a deposit starting from around 5% of the property price, although the amount you need will depend on your circumstances and the mortgage options available to you.

Whether you are buying your first home in Swansea, moving elsewhere in South Wales or simply trying to understand what is realistic, this guide explains mortgage deposits in plain English.

What is a mortgage deposit?

Your mortgage deposit is the amount being contributed towards the purchase price that is not covered by the mortgage. It may come from your own savings, a gift from family or another acceptable source. The mortgage covers the remaining amount, subject to the lender agreeing that the borrowing is affordable and the property is acceptable.

For example, if you buy a home for £200,000 and have a £20,000 deposit, you would need a mortgage of £180,000.

That would mean:

Property price: £200,000
Deposit: £20,000 or 10%
Mortgage required: £180,000 or 90%

The percentage being borrowed is known as the loan-to-value, often shortened to LTV. Lenders will normally calculate this using the lower of the purchase price or the property valuation.

Can I buy a house with a 5% deposit?

There are mortgages available that may allow eligible buyers to purchase with a 5% deposit. On a £200,000 property, a 5% deposit would be £10,000 and the mortgage required would be £190,000.

However, having a 5% deposit does not automatically mean that every lender or mortgage will be available. Your income, monthly commitments, credit history, the type of property and the lender's individual criteria will all be considered.

This is why it is helpful to have an initial consultation before setting your property budget. You can then understand not only how much you may be able to borrow, but also what deposit you are likely to need for your particular circumstances.

Is a bigger mortgage deposit better?

A larger deposit can sometimes give you access to a wider choice of mortgages or more favourable interest rates because you are borrowing a smaller percentage of the property value.

Mortgage products are often arranged in loan-to-value bands, such as 95%, 90%, 85%, 80% and 75%. Moving into a lower LTV band may improve the options available, but it is important to look at the overall cost and not assume that using every penny of your savings as a deposit is automatically the best decision.

You may still need money for legal fees, a survey, moving costs, furniture, repairs and Land Transaction Tax where applicable. Keeping an emergency fund can also be important once you become responsible for a home.

How much deposit should I aim for?

There is no single deposit amount that is right for everyone. A useful starting point is to compare what a 5%, 10% and 15% deposit would look like for the property price you have in mind.

On a £180,000 home, 5% is £9,000, 10% is £18,000 and 15% is £27,000.
On a £220,000 home, 5% is £11,000, 10% is £22,000 and 15% is £33,000.
On a £250,000 home, 5% is £12,500, 10% is £25,000 and 15% is £37,500.
On a £300,000 home, 5% is £15,000, 10% is £30,000 and 15% is £45,000.

The best target will depend on how much you can comfortably save, what you may be able to borrow and whether retaining some savings would leave you in a stronger position after completion.

Can my family help with my deposit?

Yes, many lenders accept a gifted deposit from a family member. The person giving the money will usually need to confirm that it is a genuine gift, does not need to be repaid and does not give them an ownership interest in the property.

The lender and solicitor may also ask for identification, bank statements and evidence showing where the money has come from. These checks are a normal part of the process.

If the money is intended to be repaid, it is not normally treated as a straightforward gifted deposit. It is important to explain the arrangement from the beginning so the case can be assessed correctly.

What if my deposit is coming from somewhere else?

A deposit can come from several sources, including personal savings, a Lifetime ISA, an inheritance, the sale of another property or, in some circumstances, a gift from family.

Whatever the source, you will normally need to provide a clear paper trail. If you are saving regularly, keeping the money in an account in your name and retaining a clear record of any transfers can make it easier to evidence the deposit later.

If your deposit is coming from a less straightforward source, discuss it before applying for a mortgage. Different lenders can take different approaches.

What happens if the property is valued for less than I offered?

A lender will normally base its mortgage calculation on the lower of the purchase price or its valuation of the property.

For example, if you agree to pay £200,000 but the lender values the property at £190,000, the amount it is prepared to lend may be calculated against £190,000. This could mean that you need a larger deposit, choose a different mortgage option or try to renegotiate the purchase price.

A downvaluation does not always mean the purchase cannot proceed, but it is important to review the figures carefully before deciding what to do next.

Remember the other costs of buying in Wales

Your deposit is not the only money you may need. Buyers should also budget for costs such as:

Solicitor or conveyancer fees
Searches and registration costs
A property survey
Mortgage product or valuation fees where applicable
Land Transaction Tax, depending on the property price and your circumstances
Removal costs, furniture and initial repairs

Land Transaction Tax applies in Wales rather than Stamp Duty Land Tax. Your solicitor can confirm what applies to your purchase, and the Welsh Government provides an online calculator.

Should I wait until I have a bigger deposit?

Not necessarily. Saving a larger deposit could improve your mortgage options, but property prices, interest rates and your own circumstances may change while you wait.

The most useful step is to find out what may be possible now. You can then compare the options properly and decide whether you are comfortable moving forward or whether saving for longer would put you in a better position.

An initial conversation does not commit you to applying for a mortgage. It can simply give you a clear target and a plan.

Frequently asked questions

What is the minimum deposit for a mortgage in Wales?

Some eligible buyers may be able to purchase with a deposit of around 5%, but this depends on their circumstances, the property and the lender's criteria. A larger deposit may provide access to a wider range of options.

How much deposit do I need for a £200,000 house?

A 5% deposit would be £10,000, a 10% deposit would be £20,000 and a 15% deposit would be £30,000. You will also need to budget separately for the other costs of buying.

Can I use a gifted deposit?

Many lenders accept gifted deposits, commonly from close family members. The gift and the source of the money will need to be evidenced, and the exact requirements vary between lenders.

Do I need a deposit before speaking to a mortgage adviser?

No. Speaking to a mortgage adviser early can help you understand how much you may need to save and what property budget could be realistic. You do not need to wait until you feel completely ready.

Is Land Transaction Tax included in my deposit?

No. Your mortgage deposit goes towards the property purchase price. Any Land Transaction Tax due is a separate cost, so it needs to be included in your wider buying budget.
