Finding the right mortgage for you

A mortgage is a loan to buy a property or land. It’s usually taken out over 25 or more years and the loan, plus interest, is paid off each month.

Choosing the right mortgage is one of the most important financial decisions you’ll ever make. You need to make sure you can afford repayments, not just now but years in the future.

Whether you’re buying your first home, moving to a new house or re-mortgaging, we've got a simple way to help you get the right mortgage for you:

What types of mortgage are there?

The right mortgage isn’t quite as simple as choosing the deal with the best interest rate. The type of mortgage you need depends on your financial situation, your future plans and the type of property you’re looking to buy.

Fixed rate mortgages

With a fixed rate mortgage, your repayments are guaranteed to stay the same for a set term, usually two or five years.

The advantage of a fixed interest rate is this security – knowing that your mortgage payments will stay the same for a certain length of time.

Fixed rates are sometimes higher than variable rates, but that’s not always the case. 

The main disadvantage of them is that you won’t benefit from a reduction in costs if interest rates fall.

Variable rate mortgages

If you’re on a variable rate mortgage, your monthly payments can change, because your lender can change the rate of interest it charge you. That can make it more difficult to budget for.

Variable rate mortgages will generally change when the Bank of England changes its base rate.

Interest rates and fees for variable mortgage deals can sometimes be lower than for fixed rates.

There are a few different types of variable rate mortgages:

  • Standard variable rate (SVR) mortgage – your lender’s standard interest rate for mortgages. You’ll be moved onto this at the end of a time-limited mortgage rate if you don’t switch and it’s likely to be much higher than the rate offered on a new deal.
  • Discount mortgages – your interest rate tracks your lender's standard variable rate minus a set percentage. If your lender’s SVR goes up by 1%, the rate you pay will go up by 1% as well.
  • Tracker mortgage – your interest rate tracks the Bank of England base rate plus a set percentage. So if it reduced by 1%, your mortgage interest rate will also reduce by 1%.

Offset mortgages

An offset mortgage links your savings to your mortgage and 'offsets' their value against the loan balance.

In practice, this means you'll pay less interest on your mortgage. For example, if you had a mortgage of £100,000 and savings of £20,000, you’d only pay interest on £80,000 of your mortgage.

But it also means your actual savings won't earn any interest and you might not have unrestricted access to your money.

An offset mortgage can make sense when mortgage rates are high or savings rates are very low.

How much can I borrow for a mortgage?

Your mortgage lender will look at your affordability and decide how much you can borrow. It’ll base this decision on:

  • Your salary. Or a combination of your salaries if you’re applying for a joint mortgage
  • Any additional income you have, like bonuses or tax credits
  • The size of your deposit. You’ll usually need at least 5%-10% of the total loan value
  • Any financial outgoings you have – bills, credit cards or insurance payments
  • Your credit history. A good credit history of meeting repayments will give you access to better deals

How much deposit do you need for a mortgage?

If you’re looking to buy a home, most lenders will expect you to have a deposit of at least 5%-10% of the property’s value.

A larger deposit will let you access better mortgage deals.

If you’re struggling to build a deposit, government schemes like Help to Buy and Right to Buy will help you to buy a home with a smaller deposit.

How does a mortgage work?

There are two different ways to pay for your mortgage – repayment or interest-only.

Repayment mortgages

With a repayment mortgage, you’ll pay back what you’ve borrowed, plus any interest, over the term of your mortgage.

Each month, your mortgage will get a bit smaller, until you’ve repaid the whole loan. Then, you’ll own your home outright.

Interest rates are usually lower on a repayment mortgages than an interest-only mortgage,you’re your monthly repayments will be higher as you’re paying off the capital and the interest.

Interest-only mortgages

On an interest-only mortgage, you only pay the interest that builds up on your mortgage each month. You pay nothing towards the capital (the amount you borrowed). This will make your monthly repayments lower.

At the end of your mortgage term, you’ll need to repay the capital. You’ll need a plan for how you’ll do this – separate investments, or simply selling the property.

Interest-only loans are most common for buy-to-let mortgages and aren’t widely available for residential mortgages.

What type of mortgage do I need?

Get one step closer to your perfect mortgage deal by viewing a range of mortgages you’re eligible for before you apply. First, decide what type of mortgage you need.

First home

First home mortgages are for those who have never owned or inherited residential property before.

You won’t qualify as a first-time buyer if you’ve ever owned a commercial property with living accommodation, or if you’re looking to buy a property with someone else who’s previously owned a home of their own.

Moving home

These mortgages are suitable for those who are planning on or considering moving house.

Some mortgages can be taken with you your new home (known as ‘porting’). Just be aware that your credit score will be rechecked and there might be complications if the new property is worth significantly more or less than your current one.


If your current mortgage deal’s ending in less than six months or you’d like to see if you can save money on your existing repayments, you need a remortgage.

A remortgage deal might also be right for you if you want to borrow more money, or to switch to a repayment mortgage from interest only.

Buy-to-let mortgages

If your mortgage is for a property that you plan to rent out to tenants, you’ll need a buy-to-let mortgage.

Interest rates and fees are usually higher than residential mortgages, and you may need previous experience of being a landlord to be eligible.

What information do I need to apply for a mortgage?

Get your details together before you start, so we can find you the best deal. We’ll ask for things like:

  1. Your current situation

    Whether you’re a first-time buyer, moving to a new property or remortgaging your existing one

  2. Your details

    Your name, address, and whether you’re making a single or joint application

  3. Details of the property you’re buying

    Whether it’s a new build, a house or a flat

  4. How much you want to borrow

    Usually the value of the property you’re buying, minus your deposit. If you're not sure, you can give an estimate based on your budget

  5. How much you earn

    Your salary before tax, plus any extras like bonuses or overtime

Tips to help you find a better mortgage rate

Comparing mortgage deals isn’t the only way to find great rates. Here are five more tips to help you get the deal you want:

  1. Improve your credit score

    Lenders will check your credit history against their criteria when deciding how much to lend

  2. Get on the electoral register

    A really simple but effective step towards improving your credit score

  3. Build your deposit

    A bigger deposit means you won’t need to borrow as much and you’re likely to be offered better rates

  4. Pay your bills

    Paying your bills regularly and on time will be reflected in your credit score and shows lenders you’re reliable

  5. Check your eligibility

    Use an eligibility checker to find out which mortgages you qualify for without affecting your credit score

  6. Start planning early

    It can take a while to build or repair your credit score. Mortgage lenders can check the last six years of your credit history, so it’s worth preparing early
