How to save money for a house

Read the article

When you're looking to buy a house, the first thing you need to think about is saving up for a house deposit. 

A house deposit is a lump sum of money that you pay towards the cost of a property. You’ll need a house deposit to get a mortgage, which is essentially a loan you can use to buy a home.

Here's how to start saving money for a house: 

Work out how much money you’ll need to save

Research found that you need an average salary of nearly £54,000 to afford a typical first-time buyer property on your own in 20 major UK cities. But the amount you need to save may be more or less than this. 

It depends on things like:

1. How much you want to borrow

A house deposit is a percentage of the price of a property.For example, if you saved £20,000 for a £200,000 house, you’d have a 10% deposit. This means you’d need a 90% mortgage.

You’ll usually find mortgages of up to 95%. It’s rarer to find a 100% mortgage these days, and these typically require a guarantor.

Generally, putting down a larger deposit means smaller monthly mortgage payments, since you owe less overall. It can also get you a lower interest rate – but be aware that mortgage providers tend to look at deposits in multiples of five. For example, you may get a better rate for a 10% house deposit than a 5% one, but bumping it up to 7% is unlikely to make a difference.

2. The property price

The more expensive the house, the more you’ll need to save. Prices often depend on location and type of property, among other factors. Here’s an example of how they can vary:

  • Average detached house in London – £943,905

  • Average semi-detached house in London – £598,120

  • Average semi-detached house in North East England – £133,226

You can explore prices in your area on the government’s land registry website.

Work out how much you can actually save

Now you have a better idea of how much you need for a house deposit, it’s time to do a reality check. Take a look at your finances to see what you can put away each month, and how long it’ll take you to get to your target.

If you’re saving over several years, remember that your income and outgoings may change – for example, you might get a higher paying job or start a family.

If you’re not happy with the result, think about how to reduce the amount you need for your deposit, or increase the amount you can save. For example:

1. Could you reconsider your goals?

You might be aiming too high when it comes to your property price. Try exploring different locations and property types to find options that fit your budget better. 

Ultimately, it’s up to you whether you decide to compromise – and on what factors.

2. Could you share the cost?

Partner up with someone you trust

Buying a house with a partner, relative or friend can reduce the amount you need to save. You can pool your savings to create a bigger deposit, which you can use to get a joint mortgage. 

Just remember, there are risks to sharing your finances. And you’ll also need to consider things like how you want to share ownership, and what happens if you break up or fall out.

If you’re looking to pool your resources, you could open a joint account with Monzo.

Consider shared ownership

Another option is using a shared ownership scheme. These let you buy part of a home and pay rent to a housing association on the rest. This means you can get on the property ladder even if you can’t afford the deposit for a whole home. 

Plus, shared ownership schemes usually let you increase the percentage you own when you can afford to buy more.

3. Could you put more money away?

Budget better

Taking a good look at your spending patterns may help you find ways to save more. Remember that even small changes – like buying cheaper brands or swapping taxis for buses – can make a big difference in the long-term. 

You could also consider a big lifestyle change to help you save intensively, like renting somewhere significantly cheaper or moving in with relatives if you can. 

Starting a saving plan is also be helpful if you’re looking to put more money away. Find out more about how to start a savings plan. 

Consider your current debt

It’s important to assess your current debt as well. Are you paying high interest rates on an overdraft, credit card or loan? Saving money while paying interest can feel a bit like shovelling snow while it’s still snowing. So, it may be a good idea to pay off your debt first.

Find ways to increase your income

Finally, it’s worth thinking about how you could increase your income. Landing a higher salary or finding a side job could give you more money to squirrel away.

Work out if you could you boost your savings with the right account

It pays to be picky when choosing a savings account. Getting one with a high interest rate can help your money grow by itself – especially if your lender uses compound interest. There are many different savings accounts to choose from, from a large variety of banks and building societies.

What’s a Help To Buy ISA and a Lifetime ISA?

If you’re saving money for a house, you may find it useful to open a Help to Buy ISA or a Lifetime ISA

These are savings accounts specifically designed to help you save money towards your first property purchase. You’ll get a small amount of interest from the bank, as well as the bigger benefit of a bonus from the government. 

They’ll give you 25% of your savings on top, if and when you use those savings to put a deposit on a home. Just make sure you understand the criteria and risks first.

The exact account you choose depends on a few things, including the price of the property you want to buy, when you want to buy it, and how much you can save.

Don’t forget there are extra expenses when buying. These can include:

  • Stamp duty

  • The tax you pay on properties you buy (though if you’re a first time buyer and the house costs less than £300,000 you’re exempt)

  • Fees for solicitors and surveys

  • Mortgage arrangement fees

  • Hiring a removal van

Help to Buy ISA explained

Focussing your savings into a Help to Buy ISA might be helpful if the property costs no more than £250,000 (or £450,000 if you’re buying in London). 

Here are some important things to consider when it comes to Help to Buy ISAs:

  • They’re flexible. This means you can take your money out whenever you want without losing anything (although you won’t get the bonus unless you’re taking out the money to buy a property).

  • They offer about 2% interest, which is as good a rate as you’ll get on most other normal savings accounts. 

  • How much you can save into a Help to Buy ISA is limited to £200 a month (or £2,400 a year), meaning you can only get a maximum bonus of £50 a month (or £600 a year) on top

  • You don’t actually get the bonus until you’ve completed on your property purchase, so you can’t consider this money as part of your initial deposit

 If you’re not totally sure if or when you’ll be able to buy, but you want to start saving and see if you can get there, a Help to Buy ISA could work particularly well for you. If in a few years you change your mind, you won't have lost anything.

Lifetime ISA explained

A Lifetime ISA might suit you if the property you’re looking to buy costs no more than £450,000 wherever you buy.

You can save up to £4,000 a year, meaning you could pay in up to £333 a month each if you wanted (although unlike the Help to Buy ISA you’re not even restricted to saving monthly). You can get up to a £1,000 a year bonus on top, and you can use it to buy a house worth £450,000 anywhere in the country.

Here are some important things to note about a Lifetime ISA:

  • You get the bonus when you exchange on your house 

  • You have to be under 40 to open the account 

  • You’ll also have to wait longer before you can use a Lifetime ISA to buy a house – at least 12 months from opening the account!

  • Lifetime ISAs aren’t flexible, which means you’ll be penalised if you want to take out your money without using it to buy a property. You’ll lose the bonus, interest, and some of your savings too. The only exception is if you use a Lifetime ISA like a pension, then you can get the bonus when you turn 60.
