LTV and why it’s important

LTV, or loan-to-value, is one of the key figures lenders use when considering a mortgage. It compares how much you’re borrowing to the value of the property you want to buy (or refinance).

Understanding LTV can help you plan your deposit, anticipate how mortgage costs may change, and make more informed decisions—whether you’re buying your first home, moving home, or remortgaging.

What does LTV mean?

LTV is expressed as a percentage.

• Lower LTV usually means you’re borrowing less compared with the property value.
• Higher LTV usually means you’re borrowing more compared with the property value.

Simple example

If a property costs £500,000 and you put down a £100,000 deposit, your mortgage would be £400,000.

• LTV = £400,000 ÷ £500,000 × 100 = 80%

In this example, you’ve put down 20% of the purchase price, and the mortgage covers 80%.

How is LTV calculated?

LTV is calculated using:

Mortgage amount ÷ Property value × 100

The “property value” is typically based on the purchase price for a new mortgage, or the valuation used for remortgaging.

Why it can change over time

Even if you don’t move house, your LTV can reduce as:

• you make mortgage payments (repaying capital)
• the property value changes (depending on the market)

That’s why it’s useful to keep an eye on LTV during the life of your mortgage—because it may affect what options are available later.

Why lenders care about LTV

Lenders use LTV as a way to measure risk.

In general terms, a higher LTV means the lender has less “buffer” if property values fall, because the mortgage balance is larger relative to the home’s value.

As a result, lenders may:

• price mortgages differently by LTV band
• apply stricter conditions for higher LTV lending
• offer more competitive deals at lower LTV levels (where available)

This is one reason deposits matter: increasing your deposit reduces your LTV.

How LTV can affect mortgage pricing

Mortgage pricing is influenced by many factors, but LTV is a major driver.

In general terms:

• Lower LTV can give access to a wider range of mortgage products and may be associated with more competitive pricing.
• Higher LTV can lead to higher interest rates or fewer options, reflecting the increased risk profile.

It’s also common for lenders to treat LTV as a threshold-based measure. Being just above or below a particular LTV range can affect the products you can access.

Typical LTV bands you may hear about

You’ll often see mortgages discussed in broad LTV ranges. While exact bands vary by lender and product type, it’s common to see groupings such as:

• Up to around 60%
• Around 60% to 80%
• Around 80% to 95%
• Above 95%

If you’re planning a purchase or remortgage, it can help to think in terms of which LTV band you’re likely to fall into.

LTV for first-time buyers

For first-time buyers, LTV is often especially important because deposits are frequently smaller.

Some government-backed schemes may help reduce the effective deposit requirement, which can make higher-LTV borrowing more achievable for eligible buyers. Where a scheme is involved, the way lenders assess risk can differ from a standard purchase, but the underlying concept remains: lenders still consider how much of the property value is being financed.

LTV for remortgaging

Remortgaging isn’t only about switching to a new deal—it can also be about improving your position.

Over time, your LTV may reduce because:

• you’ve paid down some of the mortgage balance
• the property has increased in value

A lower LTV at remortgage time can potentially open up different product options and pricing tiers.

How to reduce your LTV (and why it may help)

If your LTV is higher than you’d like, there are a few common ways to bring it down:

• Increase your deposit: more deposit means a smaller mortgage and a lower LTV.
• Choose a lower purchase price: buying a property with a lower price relative to your available deposit can reduce LTV.
• Wait and build equity: paying down the mortgage or waiting for market value changes can reduce LTV.

Even small changes can matter if you move into a different LTV band.

Buying with a higher LTV: what to expect

It’s not impossible to buy with a higher LTV, but you should expect:

• more limited product choice
• potentially higher interest rates
• more emphasis on factors such as affordability and credit profile

Because lenders manage risk carefully at higher LTV levels, it’s often worth reviewing your overall mortgage affordability position—not just the deposit.

The bottom line

LTV is a simple ratio, but it plays a big role in mortgage decisions. It helps lenders understand the balance between the mortgage amount and the property value, which can influence the mortgage products available and the pricing you’re offered.

For home buyers, first-time buyers and remortgagers alike, the practical takeaway is clear: a lower LTV often improves your options. Planning your deposit and monitoring how your LTV changes over time can make a meaningful difference to your mortgage journey.
