Types of mortgages explained



What is a mortgage?

At its simplest, a mortgage is a loan, paid off over a long period, to help you buy a property.

This loan is secured against the property you’re buying – so if you fail to repay your loan to the bank or building society from which you borrowed, they could repossess the property to recoup their loan.

Mortgages typically last for around 25 years, but you can borrow over shorter or longer terms.

How does a mortgage work?

When you take out a mortgage, you’ll have to repay two parts – the ‘capital’ (the actual loan to buy the property) and the ‘interest’ (what your lender charges to lend you money).

But there are different mortgage options available to you.

Repayment mortgage – with these mortgages, your monthly repayments pay off interest and capital at the same time, until your loan is repaid in full at the end of the term.

Interest-only mortgage – with these mortgages, your monthly repayments only pay the interest, none of the capital. When you come to the end of your mortgage term, you’ll have to pay all of the capital back, so will need a plan to meet this large repayment.

What are the different types of mortgage deal?

Once you’ve decided what kind of mortgage you want, there’s more for you to decide. Mortgage deals come in a variety of forms, and the deal you end up choosing will depend on your circumstances and needs both at the time of applying and in the future.

The different types of mortgage deal include:

  • Fixed-rate mortgages
  • Tracker mortgages
  • Discount mortgages
  • Standard variable rate mortgage

What is a fixed-rate mortgage?

A fixed-rate mortgage can provide financial stability. Your interest rate stays the same for a set period of time and, therefore, your monthly mortgage repayments remain the same.

This is in contrast to a variable-rate mortgage, which will go up or down in relation to the Bank of England base rate, or your lenders’ standard variable rate (SVR).

The term of a fixed-rate mortgage usually lasts between two to five years, but can be much longer. When this period comes to an end, your lender will typically transfer you automatically onto its SVR so it’s important to review your situation before this happens.

Fixed-rate mortgage benefits

Fixed-rate mortgages give you peace of mind. You know your monthly mortgage repayments won’t rise for the length of your deal, even if your lender’s SVR or the Bank of England base rate does.

This can help you to plan ahead and budget more easily for other household and day-to-day expenses, without facing any nasty repayment surprises.

A fixed-rate mortgage may be the right choice if you’re on a tight budget and need the certainty and stability of a fixed monthly payment.

Fixed rate mortgage drawbacks

In the current low-rate environment, fixed mortgages are a little more expensive than variable rate deals.

Furthermore, if rates were to drop, customers on a fixed-rate deal would not see any of the benefits.

What is a tracker mortgage?

A tracker mortgage is a type of variable-rate mortgage. The interest rate tracks the Bank of England base rate at a set margin (for example, 1%) above or below it.

Tracker mortgage deals can last for as little as one year, or for the total life of the loan.

Once your tracker deal comes to an end, you’re likely to be automatically transferred on your lender’s standard variable rate (SVR). Typically, this will have a higher rate of interest, so make sure you review your mortgage in time.

Tracker mortgage benefits

In certain economic circumstances, borrowers can secure tracker mortgage deals with very low rates of interest. For example, with the current, historically low base rate of 0.75%, a +1% tracker mortgage would charge a rate of just 1.75% interest.

While your tracker mortgage rate is low, you can take the opportunity to overpay on your mortgage, shortening the total length of time it takes you to pay off your mortgage and cutting the amount of interest you pay.

In addition, your rate is not dependent on the whim of your lender, it is not affected by changes in your lender’s SVR – just changes in the base rate.

Tracker mortgage drawbacks

On the other hand, as a variable deal, a tracker mortgage will not provide total rate security. If the base rate suddenly rises, so will the interest rate you pay.

This means that a tracker mortgage may not be suitable for someone on a tight budget, who needs to know exactly how much their monthly mortgage repayments will be. In these circumstances, it may make sense to choose a fixed-rate mortgage instead.

If you want to leave a tracker mortgage deal before the end of the set term, you’re likely to be charged an early repayment fee.

What is a discount mortgage?

A discount mortgage is a type of variable-rate mortgage. The term ‘discount’ is used because the interest rate is set at a certain ‘discount’ below the lender’s standard variable rate (SVR) for a set period of time.

For example, if a lender has an SVR of 5% and the discount is 1%, the rate you’ll pay will be 4%. And if the SVR is raised to 6%, your discount rate will also rise – in this case to 5%.

Discount mortgage deals typically last between two and five years. When your discount mortgage deal comes to an end, your lender will typically transfer you automatically onto its SVR.

Discount mortgage benefits

Having a discount mortgage means you can be sure that your rate will always remain below your lender’s SVR, for the length of the deal.

In certain economic circumstances (for example, when SVRs are generally low as a result of a low base rate) this may mean your discount mortgage deal has a very low rate of interest.

Discount mortgage drawbacks

Because your discount rate tracks your lender’s SVR – and you have no control over what that SVR is – a discount mortgage does not offer much rate stability.

And borrowers with large discounts below their lenders’ SVR may be in a particularly vulnerable position when their discount mortgage deals come to an end. This is because they could face large and sudden rate hikes when they’re transferred onto their lenders’ SVRs.

So, if you’re on a tight budget and need your repayments to stay the same from month to month, it may make sense to choose a fixed-rate mortgage.

In addition, you may face early repayment charges if you pull out of a discount mortgage deal before the end of the term.

What is a standard variable rate mortgage?

A standard variable rate mortgage (also known as an SVR or reversion-rate mortgage) is a type of variable rate mortgage. The SVR is a lender’s ‘default’ rate – without any limited-term deals or discounts attached.

When a fixed, tracker or discount mortgage deal comes to an end, you will usually be transferred automatically onto your lender’s SVR.

A lender can raise or lower its SVR at any time – and as a borrower, you have no control over what happens to it.

Who sets standard variable mortgage rates?

Standard variable rates tend to be influenced by changes in the level of the Bank of England’s base rate. However, a lender may also decide to change its SVR while the base rate remains unchanged.

Lenders’ standard variable rates typically range from around 2% above the base rate (currently set at 0.75%) to 5% above it or even more.

Standard variable rate mortgage benefits

When the Bank of England base rate stood at a historic low of 0.25%, lenders significantly cut their SVRs to reflect this.

Now that it has risen to 0.75%, lenders have responded by increasing their SVRs. This is still low by historic standards.

So, if your previous mortgage deal has come to an end and you have been transferred onto a low SVR, you may be able to take advantage of that low rate by staying on it, and not looking for another deal.

They often don’t have any early repayment charges, leaving you free to review and switch your mortgage whenever you like.

Standard variable rate mortgage drawbacks

Staying on your lender’s SVR is a very risky strategy – as it offers no rate security.

If you are on a tight budget and relying on your SVR to remain low, you’re in a very vulnerable position. In this case, it is very important you try to remortgage onto a fixed-rate deal (which offers rate stability) before it’s too late.
