KEY INFORMATION

Types of mortgages: At a glance

Here are the main types of mortgages to choose from:

Fixed rate mortgages

When you’re taking out a mortgage, one of the biggest decisions is whether to take out a fixed rate or a variable rate mortgage. So it’s vital that you understand the difference between these types of mortgages so that you can pick the right one for you.

What are fixed rate mortgages?

A fixed rate mortgage is a home loan where the interest rate and monthly payments stay the same for a set period, usually 2, 3, 5 or 10 years.

Fixed rate mortgages are a popular option, because you know exactly what your monthly repayments will look like over a set period.

However, while the rate you’ll pay won’t go up during your term it won’t go down either. Read more in our guide Fixed rate mortgages: pros & cons, latest rates and how to apply.

To consider whether to fix for a shorter or longer period of time, see our guide: 2 or 5 year fixed rate mortgage.

Pros and cons of fixed rate mortgage deals

Pros

  • Budgeting certainty: Your payments are predictable which helps with managing your household finances.

Cons

  • Missed savings: With this type of mortgage, while your mortgage payments won’t increase if interest rates rise, they won’t go down if interest rates fall.
  • Less flexibility: You will usually need to pay an early repayment charge to leave a fixed rate mortgage before the end of your deal.

Variable rate mortgages

Variable rate mortgages are different to fixed rate mortgages because the rate you pay can go up or down. There are three main types of variable rate mortgages and they each work in different ways.

1. Tracker mortgages

If you take out a tracker mortgage, the rate you pay goes up and down in line with the Bank of England’s base rate.

  • For example, if you take out a tracker mortgage that is the base rate plus 1%, the rate you’ll pay will be 1% above the Bank of England base rate. So if the base rate falls by 0.25%, the rate you’ll pay will also fall by 0.25%.

Tracker mortgages usually last for between two to five years, after which the rates revert to the lender’s standard variable rate, which can be much more expensive.

Tracker mortgages pros and cons

Pros

  • Your rate could go down: Tracker mortgage rates can go down.
  • Transparency: Your rate will automatically go down if the Bank of England cuts the base rate.
  • Flexibility: Some trackers come with no early repayment charges which means you can switch to a better rate fee-free if you find one.
  • Your mortgage rate may be capped, limiting the rate of interest you could be charged. Although these deals may cost more.

Cons

  • Your repayments could go up, if the base rate increases.

Read more in our guide Tracker mortgages explained.

2. Discounted variable rate mortgages

Unlike tracker mortgages, which track the Bank of England base rate, with this type of mortgage, the rate you’ll pay is linked to the lender’s standard variable rate.

Pros and cons of discounted variable rate mortgages

Pros

  • Your rate may go down if interest rates are cut.

Cons

  • However, your lender may not reduce its SVR if the base rate is cut, or they may delay making a cut or not pass on the full cut.
  • Lenders can increase their SVRs at will, so your rate could go up.

3. Standard variable rate mortgages

A standard variable rate mortgage is the type of variable rate mortgage you’ll usually be moved to when your fixed rate, tracker or discounted mortgage deal ends.

  • However, they can be very expensive, and you may be able to save a significant amount each month by remortgaging.

If your current mortgage deal ends in the next six months, start investigating your remortgage options ASAP, to reduce the chance of rolling onto your lender’s SVR when your current deal ends.

However, everyone’s circumstances are different. So the best way to find out if staying on your lender’s SVR is right for you is to speak to a mortgage broker.

How long do you want your mortgage deal for?

Whether you take out a fixed or variable rate mortgage, you’ll usually take it out for 2, 3 or 5 years, however some 7 and 10 year terms (or even longer) are available.

You’ll need to weigh up how long you’ll want to be tied into your deal for.

  • For example, if you’re choosing a fixed rate mortgage, you’ll need to consider how long you’d like the security of knowing how much your rate will be – but you’ll also need to think about the fact that if rates go down in the future you could be trapped paying a higher rate.
  • You should also consider whether you’re planning to move house in the future and if so, how soon.

Types of mortgage repayment: Repayment vs interest-only mortgage

You’ll also need to decide whether you want to take out a repayment mortgage or an interest-only mortgage.

Here is how these mortgage types work:

Capital repayment mortgages

  • Your mortgage payments will cover the interest on the loan and some of the capital you originally borrowed.
  • At the end of the mortgage term you will have paid off your mortgage.
  • However, your mortgage payments will be higher.
  • Most residential mortgages are on a repayment basis.

Interest-only mortgages

  • An interest-only mortgage is where your monthly payments cover only the interest due on the loan. You don’t reduce the capital, so you’ll still owe the full balance at the end of the term.
  • This means your mortgage payments will be lower, but at the end of the mortgage term you will still owe the original amount you borrowed which you will need to repay.
  • These are common for Buy to Let mortgages but can be difficult to get otherwise.
  • However, what’s right for you depends on your circumstances. For example, they may suit homeowners who are asset-rich or who earn significant bonuses which they can use to pay off chunks of the capital.
  • Another type of mortgage available are retirement interest-only mortgages which are designed for older borrowers who want to live in their home without paying off their mortgage. See more information in our guide What are retirement interest-only (RIO) mortgages and should I get one?

Buyer type

The types of mortgages available for you will depend on your circumstances, including what type of buyer (or remortgager) you are.

First time buyer mortgages

You may have a number of different types of mortgages available to you if you’re a first time buyer. These may let you:

  • Borrow a bigger loan, through offering a larger multiple of your income.
  • Get a mortgage with a smaller, or even no deposit, such as 100% mortgages.

Read more in our guide to First time buyer mortgages.

Residential

This is the type of mortgage (or remortgage) for people taking out a loan on a property they will live in.

If you take out a residential mortgage, you can’t usually let the property out unless you have consent from your lender.

You’ll usually need at least a 5% deposit to take out a residential mortgage, although you can get a mortgage with a smaller, or even no deposit.

This is the most common reason for getting a mortgage in the UK.

Buy to Let mortgages

Buy to Let mortgages are the type of mortgage landlords take out if they’re buying or remortgaging a property that will be let out to tenants.

Buy to Let mortgages are similar to residential mortgages but there are some key differences:

  • The amount you can borrow is based on how much rental income the property can generate. Lenders typically require your expected rental income to meet at least 125% of the monthly interest payments. To get a rough idea of how much you could borrow, use our Buy to Let mortgage calculator. You may need a minimum salary too, typically £20,000-£25,000.
  • Buy to Let mortgage rates are typically higher than standard mortgages due to the greater risk involved. Find the Best Buy to Let mortgage rates (updated daily).
  • You’ll usually need at least a 20-25% deposit, plus arrangement fees can be higher than for residential mortgages and most Buy to Let mortgages are interest-only.

Let to Buy

This type of mortgage is also designed for people who are letting out a property but they work differently because Let to Buy involves renting out your current home and buying a new one to live in:

  • You’ll switch your current mortgage to a Let to Buy mortgage
  • You’ll take out a new mortgage on the property you’re buying.

This allows you to keep your original property as an investment, with the aim of earning rental income and benefiting from any increase in property value.

Let to Buy can be a popular option with couples wanting to move in together, but each have their own property. In this case, you could both move into one of the properties and rent the other one out using a Let to Buy mortgage.

Other mortgage types

Offset mortgages explained

An offset mortgage is a type of mortgage that allows you to use your savings to reduce the amount of interest you pay on your mortgage.

  • For example, if you have £10,000 in savings, and a £100,000 mortgage, you would only pay interest on £90,000.

However, these mortgages may have higher interest rates. Find out more about offset mortgages, the pros and cons and how they work.

Guarantor mortgages

Guarantor mortgages are a type of mortgage that allow a relative to act as a guarantor, using either savings or their own property as security.

You can usually borrow a larger amount than you would be able to on your own. In fact some guarantor mortgages will let you borrow 100% of the property’s value.

Find more information on how guarantor mortgages work, the risks and popular options such as Barclays Family Springboard.

Green mortgages

Green mortgages reward you for saving energy in your property.

  • Some lenders will give you lower interest rates or cashback and larger loans if your home meets a minimum energy-efficiency level.
  • Other mortgage lenders will offer lower rates or cashback if you make energy-efficiency improvements. Or if you take out additional borrowing to pay for measures to improve your home’s energy efficiency.
  • There are a number of lenders already offering green mortgages including Nationwide, NatWest, Barclays, Kensington and Saffron Building Society and more.

What mortgage term should I opt for?

The most common mortgage term length has traditionally been 25 years, however the average length of mortgage for first time buyers has increased in recent years.

In fact, the number of borrowers taking out ultra-long mortgages of more than 35 years has tripled since 2020, according to Thisismoney.co.uk.

Some people prefer taking a mortgage out over a longer term because it can make repayments more affordable, however, it also means you’ll pay more interest over the life of your mortgage.

See our guide on 30 year mortgages to help you weigh up the pros and cons of a longer mortgage term.

Frequently Asked Questions

What are the main types of mortgages in the UK?

The main types of mortgages in the UK are fixed rate, tracker, discount and standard variable rate mortgages.

What is the difference between a repayment and interest-only mortgage?

With a repayment mortgage, you pay back both the loan and the interest each month, so the mortgage is fully paid off at the end of the term. With an interest-only mortgage, you only pay the interest, meaning you must repay the original loan separately.

Is a fixed rate mortgage better than a variable rate mortgage?

Some people prefer a fixed rate mortgage because it gives certainty, as your payments stay the same for a set period. However, others prefer variable rate mortgages. Which is better for you depends on your circumstances.

Can first time buyers choose any types of mortgages?

Generally speaking, most first time buyers can choose from the same types of mortgages as existing homeowners, although interest-only mortgages may be less common. Also, some deals are specifically designed for first time buyers, often with smaller deposit requirements.

However, the types of mortgages you’ll be able to access will depend on your circumstances so it’s a good idea to get fee-free mortgage advice.
