Step 1. Get purchase ready

Review your finances

Buying your first home is a big step, and there’s a lot to think about. The first thing you’ll want to do is review your finances to make sure you’re ready when you find the perfect property.

Consider things that will improve your chances of getting a mortgage, such as your deposit amount and credit rating.

Home buying costs to consider

You'll need to consider other costs when buying a home like Stamp Duty, legal fees, surveys, mortgage product fees, home insurance, and moving home costs.

You can check out stamp duty costs and rules on the Gov.uk website (opens in a new window).

Get an idea of what you could afford

Look at your income, or what you get paid, against your outgoings like bills, regular spend and other debts to work out how much money you'd have left each month. Ask yourself if you have enough to cover a monthly mortgage payment.

Our mortgage borrowing calculator will give you an idea of what you might be able to borrow, based on things like income, deposit and property value.

You can also compare mortgage rates and find the perfect deal using our mortgage rates calculator.

Affordable home schemes

Step 2. Your deposit

The size of your deposit affects how much of a mortgage loan you’ll need. For most first time buyer mortgages, you need a deposit of at least 5% of the price of the property you want to buy.

The bigger the deposit, the better access you’ll have to lower rates, and lower monthly payments.

Step 3. Get a Decision in Principle

You’ve worked out how much you can borrow and have your deposit. Now you can get a Decision in Principle and start looking at properties.

A Decision in Principle, also called Mortgage in Principle or Agreement in Principle, confirms what we’re prepared to lend you and lasts for 90 days. It lets estate agents know you ‘re ready to buy and many require one before they will accept an offer on a home.

When you apply for a Decision in Principle we’ll do a soft credit check. Soft credit checks do not affect your credit rating. They do not appear to lenders on your credit report and will not affect your ability to apply for borrowing in the future.

You can apply online and it can take about 20 minutes to complete.

A Decision in Principle is not a mortgage offer. Once you’ve found a property you like, and had your offer accepted, you’ll be ready for the next step - apply for a mortgage.

Step 4. Apply for a mortgage with us

Book a meeting with a mortgage adviser

There are two ways of booking an appointment with our mortgage advisers:

What happens when you apply for a mortgage

Step 5. Your mortgage offer

Receiving your mortgage offer

Once your mortgage has been approved, we’ll send your mortgage offer to you in the post. It’s an exciting time and is the official confirmation that your mortgage is ready to go.

You’ll find all the key details, like:

  • How much you’re borrowing
  • Your interest rate and type (fixed or variable)
  • Your monthly repayments
  • How long your mortgage lasts

You should take your time to check all the information matches your expectations. If you’re unsure about anything, one of our mortgage advisers will be happy to help.

Accepting your mortgage offer

Once you’ve read through your offer and you’re happy with everything, it’s time to accept it and that brings you one step closer to getting the keys. Here’s what happens next:

  • Sign the paperwork that came with your offer and send it back to us.
  • Let your solicitor know — they’ll use the offer to get everything ready for exchange and completion.
  • Keep an eye on the expiry date.

Step 6. Exchanging contracts and completion

Exchange of contracts

Once you’ve accepted your mortgage offer, your solicitor will begin the final steps of your home purchase.

In England, Northern Ireland and Wales, this includes agreeing a date to exchange contracts with the seller’s solicitor. The contract confirms what you’re buying, what’s included, and any terms and conditions you’ve both agreed to.

Your solicitor will send you the contract once everything is ready. You may need a witness when signing, and it’s best to return it promptly so the process can move forward without delay.

In Scotland, the process works differently. Instead of exchanging contracts, your solicitor and the seller’s solicitor agree the sale through a series of formal letters called missives. Once these are finalised (known as concluding missives), the agreement becomes legally binding. You’ll be asked to review and approve the terms along the way, rather than signing a single contract at exchange.

Get insurance that protects you and your home

You’ll need to have buildings insurance in place from exchange of contracts or from the point missives are concluded in Scotland. It covers you financially for damage to your home. At the end of your mortgage application, we’ll offer a quote for Nationwide home insurance, or you can choose a provider that suits you. If choose us, you can get a quote for buildings, contents, or both combined.

You should also consider life insurance or critical illness cover to help protect you and your family if the unexpected happens.

Pick from buildings or contents insurance - or a policy that combines both. And, for an additional cost, decide which optional extras you need.

Life insurance

Help protect your loved ones from financial worry with a life insurance policy.

Choose the type of cover that best suits you. And if you want to add critical illness cover for an additional cost.

Completion day

The day you’ve been waiting for has finally arrived! On completion day, your solicitor sends the money to the seller. Once that’s confirmed, you’ll get the keys to your new home. Usually from the agent dealing with your purchase.

The timing can vary depending on things like how quickly the money transfers and when the seller’s solicitor confirms receipt. Your solicitor should keep you updated throughout the day, so you’ll know when everything’s done and dusted.
