Understanding loan-to-value – Zoopla

If you’re thinking of buying a house and applying for a mortgage, you’ll need to know all about loan-to-value. Here’s our guide with the lowdown.

What does loan-to-value mean?

If you’re considering buying a house and applying for a mortgage you’ll quickly become used to people talking about loan-to-value, or LTV for short. But what does it mean and why does it matter?

Quite simply, loan-to-value is a way of expressing the difference between the value of the house you’re buying and the amount of money you’re borrowing to pay for it.

It is one of the main factors that your bank or building society will assess when deciding what rate to offer you for a mortgage.

The average value of a home in England is now upwards of £310,000, meaning most people will have to borrow in order to buy. 

While this might seem a daunting prospect, the mortgage industry is regulated to ensure that you can safely borrow the money and pay it back in manageable monthly instalments over a set period.

Lenders will assess your earnings and outgoings before deciding whether to offer you a mortgage.

Calculating loan-to-value

Loan-to-value describes the way in which the amount of money you’ve borrowed relates to the value of your house, usually expressed it as a percentage.

For example, if you are looking to buy a house valued at £250,000, and have saved up a deposit of £50,000, you will need a mortgage of £200,000.

£200,000 (mortgage) ÷ £250,000 (whole value) = 0.8

0.8 x 100 = 80

Your loan-to-value would be 80%, meaning that the money you’re borrowing accounts for 80% of the value of the property, and you own 20% outright.

The £50,000 deposit (available upfront as cash) is described as ‘equity’ and as the homeowner pays off the mortgage the equity will increase. 

Another way of equity increasing is if the house value rises. We’ll explore this shortly, but for the purposes of this explanation, let’s assume the house value remains the same.

Now, if after five years, you have managed to pay back £50,000 of the loan, your equity in the property will increase to £100,000 (£50,000 deposit + £50,000 paid back).

100,000 (new equity value) ÷ 250,000 (whole property value) = 0.4

0.4 x 100 = 40 

You now own 40% of your home outright and your loan-to-value will decrease to 60%.

This is where it gets slightly more complicated. Although you’ll be making monthly payments at the rate you agreed when you took out the mortgage, the value of your house is unlikely to stay the same. Home buyers must be aware that values can fall as well as rise. 

Increasing house prices

The average price of a home in Britain has historically risen over the years. It means a £250,000 house that you bought several years ago could now be worth £350,000, or even more.

What does this do to your loan-to-value? Consider this example. 

You bought a £250,000 house five years ago, putting down a £50,000 deposit and taking out a £200,000 mortgage. 

You have paid off £50,000 of the debt, so now owe the bank £150,000. But over the same period the value of the property has risen to £350,000.

This means your loan-to-value has been reduced to 43% – a great improvement on the 80% when you first purchased the property.

Falling house prices 

House prices can go down as well as up and homeowners can be caught out if they take out high loan-to-value mortgages or even interest-only mortgages on the assumption that property prices will continue to rise. 

For example, consider if you took out a £200,000 mortgage to buy a £250,000 at 80% loan-to-value, but the property’s value dropped to £200,000.

If you’ve paid £50,000 off the mortgage, you will still owe £150,000, but because the property value has dropped your loan-to-value is just 75% – only a small amount lower than it was when you started.

Negative equity

Consider a family who bought their house for £500,000 with a £50,000 deposit, taking out a mortgage of £450,000, which is 90% loan-to-value.

They then manage to pay off another £50,000, reducing their overall debt to £400,000. The problem is that their house has fallen in value to £350,000 and they now owe more on their mortgage than the property is worth – this is what is known as negative equity.

The family now has a problem if they decide to sell their house because selling it for £350,00 means they will still owe the lender £50,000.

Negative makes it difficult for the family to remortgage too.

For example, if they wanted to change to a new mortgage lender that offered a more favourable interest rate, they would probably be turned down. 

They’d need to borrow more than the property is worth and the lender would not be confident of recouping its money should they default

It means the family may end up automatically slipping on to an expensive standard variable rate mortgage at the end of their initial deal – something that does not protect them against further interest rate rises.

Why is LTV important?

Loan-to-value is one of the most central factors in deciding not only whether you can get a mortgage, but what type of mortgage you are able to take out.

Mortgage lenders are understandably careful about who they offer loans to and as well as looking closely at your income, liabilities and other assets, they will take into account the potential loan-to-value of the property you are proposing to buy.

The higher the ratio of the loan-to-value, the more risky it is for the lender. A £250,000 house, purchased with a £200,000 mortgage (loan-to-value of 80%) is a more secure deal for a lender than lending £225,000 (loan-to-value of 90%).

Mortgage providers try to reduce this risk by charging a higher rate of interest for mortgages with a higher loan-to-value.

However, although this helps protect the lenders, it can cause problems for the borrowers trying to meet higher monthly repayments. 

First-time buyers

Loan-to-value is of particular concern to first-time buyers, who might have been saving for years for a deposit.

They will usually have to opt for a higher loan-to-value, with the hope of reducing it in a few years, and potentially remortgaging at a lower rate somewhere down the line.

Although it may be tempting to step on to the property ladder as soon as you have the minimum amount required for a deposit, it is worth considering whether this makes the most sense financially.

The larger the deposit you are able to save, the lower the loan-to-value you’ll have. It means you will get a better mortgage deal and pay less in interest over the full term of the mortgage.

As you go through the process of entering into a mortgage agreement, you will also find that there are significant extra costs, including legal fees and potentially stamp duty, although this is waived for the majority of first-time buyers.

The Government’s Help To Buy Equity Loan scheme has made it possible for first-time buyers and those already on the property ladder to get a mortgage with as little as a 5% deposit by providing an interest-free 20% loan for the first five years. This allows the loan-to-value to be reduced to 75%.

Remortgaging or moving house

Loan-to-value is just as important a consideration for people moving house, or remortgaging an existing property. The amount of equity you hold in your property will affect your ability to remortgage, and may limit your options.

If you have been paying off your original mortgage for several years, and house prices have gone up or remained stable, you will hold a greater amount of equity.

It means you are able to take out a new mortgage with a more favourable loan-to-value ratio, and possibly much lower interest rates than you did before.

However, if house prices are currently going through a low point, and there is no urgent need to move, it may make sense for you to stay where you are for a couple of years.

If the value of your house goes up again, your loan-to-value will go down, which means you stand a better chance of getting a good deal if you remortgage.

Equity release schemes

At the other end of the scale are homeowners considering equity release, where money is borrowed against the value of an existing property to see them through their later years.

Just like any other mortgage, the terms of an equity release loan are dependent on your loan-to-value ratio. If you take out one of the most popular types of equity release scheme, known as a lifetime product, the interest will be added to the loan over time and paid off when your property is eventually sold, either on your death or when you decide to move into full-time care.

Equity release is only offered for relatively low loan-to-value ratios. There are few schemes that accept a loan-to-value of more than 50% and most state their maximum as somewhere between 40-45%.

For this reason, you will only normally be eligible for an equity release scheme if you have paid off your original mortgage, or if you only have a small percentage remaining.

Taking out a mortgage – or remortgaging an existing property – can often be a daunting and confusing process, with many acronyms and facts and figures to get your head round.

Loan-to-value is one of the most important of these. It is also a helpful way of understanding the actual value of a property, working out whether you can afford to buy it, and what sort of mortgage and interest rates might be available to you. 

How to work out loan-to-value 

As we’ve discovered, your loan-to-value won’t stay the same for long. Since house prices fluctuate, your loan-to-value will go up or down, even if you are only paying the interest on your mortgage, without making any difference to the debt itself.

Loan-to-value will also change throughout the lifetime of your mortgage, usually decreasing slightly with every repayment you make.

As you progress through the course of your mortgage term, and your loan-to-value evolves, so will the opportunities available to you.

You may find that you are able to renegotiate your mortgage in order to pay it off more quickly, or to get a more favourable interest rate.

Even if you have been paying off your mortgage for several years, it is in the interests of your general financial health to regularly check your loan-to-value.

You might be eligible for a better mortgage deal and save some money in the process.

Most banks and building societies classify mortgages into different loan-to-value bands. If you’re towards the bottom of the scale for loan-to-value, you’ll qualify for their lowest rate of interest.

If you’re near the top end of the scale, your interest level will be higher. Generally speaking, borrowers with a loan-to-value of 90% or above will be charged the most, while borrowers with a loan-to-value of 75% will be charged less. Borrowers with a loan-to-value of 60% or lower will be offered the most preferential rates.

Reminder: How to work out your loan to value

As shown above, simply divide the amount you are looking to borrow (or the balance of your existing mortgage) by the total value of the property, then multiply it by 100. This will give you your loan to value percentage. 

Another quick calculation example:

A buyer wants to buy a property worth £200,000 and has saved up a deposit of £50,000. They need to borrow £150,000.

£150,000 ÷ £200,000 = 0.75

0.75 x 100 = 75

Their loan-to-value is therefore 75%. 

How to influence your loan-to-value ratio

Your loan-to-value can make a big difference to how much you are allowed to borrow, what your interest rate will be, and ultimately how much your property will cost you during your repayment period.

It makes sense to do everything in your power to reduce it as much as possible.

The loan-to-value bands outlined by various banks and building societies can be a good guideline. If you are saving up for a deposit and currently have slightly less than you would need to reach a particular loan-to-value threshold, it may well be worth hanging on for a few months.

Increasing the size of your deposit – and thus, reducing your loan-to-value – may mean you then qualify for the best value loan, which will save you thousands of pounds in the long run.

An alternative, if you have found the perfect property and are unwilling to wait, is to negotiate with the seller to bring the price down.

Even a comparatively small reduction might send you into a more favourable loan-to-value band, which will not only save you money, but also improve your chances of being accepted for a mortgage.

Add property value

If you are remortgaging or moving house, you can take the opportunity to reduce your loan-to-value by repaying an extra slice of capital or finding a way of adding value to your property, in order to be eligible for the best value loan.

Converting a loft, putting in a new kitchen or landscaping a garden will cost you a few thousand pounds, and will require a survey.

But ultimately, it could increase the value of your house by much more, and could in turn send you into a different loan-to-value band. This will reduce the interest you have to pay on your new mortgage.

It is also a good idea to shop around, as some mortgage providers will only offer substantially higher rates to those borrowers with a higher loan-to-value.

Don’t forget that buying a house comes with a lot of extra costs that could eat up more of your savings than you were expecting. As well as legal fees and potentially stamp duty, it is a good idea to put aside some money for unforeseen expenses that might arise during the moving in period.

Once you have subtracted these costs, your deposit fund might be significantly smaller, and you may find you do not qualify for the loan-to-value threshold you had been hoping for. 

Mortgages to match loan-to-value

As with all big financial decisions, it pays to shop around, as mortgage providers can vary considerably in the deals they offer, especially between different loan-to-value bands.

Once you have saved up your deposit, found the property you wish to buy, and worked out your loan-to-value, you will then need to look at the terms, fees and interest rates of all the different mortgages that are available to you.

Mortgage brokers

Although you may be wary of spending yet more of your hard-earned cash, it can often pay to use the services of a mortgage broker.

They are a qualified professional who has arranged hundreds of other mortgages, understands the industry, and knows what’s currently on offer. 

Using a broker will not necessarily cost you more money. Whatever fee they might charge is often much less than the savings they help you make.

Some have access to ‘broker exclusive’ deals that are better value than those available direct from a mortgage provider.

A broker will also be able to advise you on the type of mortgage to take out, and on effective ways to maximise your assets, and save yourself the most money. 


It’s often said that buying a house is one of the most stressful experiences in life. But it doesn’t have to be.

We hope that this guide will have helped you to understand the importance of loan to value, and given you an idea of how to improve yours.
