What Is Loan-to-Value (LTV) and Why It Matters

Loan-to-value, usually called LTV, is one of the most important numbers in a mortgage application.

It affects your mortgage rate, deposit size, lender choice, approval chances and remortgage options.

A lower LTV usually means you are borrowing less compared with the property value. That can make the mortgage less risky for the lender.

A higher LTV usually means you are borrowing more compared with the property value. That can make the mortgage more expensive and reduce lender choice.

Understanding LTV helps you compare mortgage deals properly, plan your deposit, avoid over-borrowing and spot when a slightly bigger deposit or overpayment could make a real difference.

👉 Check your loan-to-value and what it means for your mortgage.

What does loan-to-value mean?

Loan-to-value is the percentage of the property value that you are borrowing as a mortgage.

The formula is:

Mortgage amount ÷ property value × 100 = LTV

For example:

Property value:  £200,000 Deposit:         £20,000 Mortgage:        £180,000 £180,000 ÷ £200,000 × 100 = 90% LTV

In this example, the buyer has a 10% deposit and a 90% loan-to-value mortgage.

Why LTV matters

LTV matters because lenders use it to measure risk.

If you borrow 95% of a property’s value, the lender has less protection if the property value falls.

If you borrow 60% of the property’s value, the lender has a much larger equity buffer.

That can affect:

  • interest rates
  • lender choice
  • mortgage approval
  • product availability
  • remortgage options
  • deposit requirements
  • down-valuation risk
  • buy-to-let lending
  • overpayment strategy
  • future flexibility

LTV is not just a technical mortgage term.

It is one of the main drivers of mortgage cost.

Simple LTV examples

Here are a few simple examples:

Property value: £250,000 Deposit:        £12,500 Mortgage:       £237,500 LTV:            95% Property value: £250,000 Deposit:        £25,000 Mortgage:       £225,000 LTV:            90% Property value: £250,000 Deposit:        £50,000 Mortgage:       £200,000 LTV:            80% Property value: £250,000 Deposit:        £100,000 Mortgage:       £150,000 LTV:            60%

The lower the LTV, the more equity or deposit you have in the property.

Common LTV bands

Mortgage lenders often price products in LTV bands.

Common bands include:

  • 95% LTV
  • 90% LTV
  • 85% LTV
  • 80% LTV
  • 75% LTV
  • 60% LTV

The exact bands vary by lender and product.

But the general principle is that lower LTV bands usually give better options.

For example, a borrower at 90% LTV may have more choice than a borrower at 95% LTV.

A borrower at 75% LTV may have more options than a borrower at 90% LTV.

A borrower at 60% LTV may be in one of the strongest pricing bands.

LTV and deposit size

Your deposit is directly linked to LTV.

A smaller deposit means a higher LTV.

A bigger deposit means a lower LTV.

For example:

5% deposit = 95% LTV 10% deposit = 90% LTV 15% deposit = 85% LTV 20% deposit = 80% LTV 25% deposit = 75% LTV 40% deposit = 60% LTV

This is why deposit size matters so much.

It does not just affect how much money you need upfront.

It can also affect the rate, lender choice and long-term cost of the mortgage.

How LTV affects mortgage rates

LTV can have a major effect on mortgage rates.

In general:

Higher LTV = higher lender risk = higher rates Lower LTV = lower lender risk = better rates

This is not guaranteed in every case, because rates also depend on market conditions, lender pricing, fees, credit history and product type.

But LTV is one of the biggest personal factors.

A borrower at 95% LTV may pay a higher rate than someone at 75% LTV, even if they have the same income and credit profile.

Over a full mortgage term, that difference can be significant.

For more detail, read how mortgage rates actually work.

LTV and lender choice

LTV can also affect how many lenders are available.

At higher LTVs, some lenders may:

  • have fewer products
  • apply stricter criteria
  • require stronger credit history
  • restrict property types
  • assess affordability more cautiously
  • limit maximum borrowing
  • price more conservatively

At lower LTVs, lenders may be more comfortable because the borrower has more equity in the property.

This does not mean low LTV guarantees approval.

But it can improve lender choice.

LTV and mortgage approval

LTV affects approval because it changes lender risk.

A high-LTV mortgage can be harder if there are other risk factors, such as:

  • tight affordability
  • credit issues
  • irregular income
  • small deposit
  • non-standard property
  • recent job change
  • high credit commitments
  • down-valuation risk

A lower LTV can sometimes make the application stronger, but it does not replace affordability.

The lender still needs to be satisfied that the mortgage is affordable.

For more detail, read how mortgage lenders assess affordability.

LTV vs affordability

LTV and affordability are not the same thing.

LTV measures how much you are borrowing compared with the property value.

Affordability measures whether you can afford the mortgage payments.

You can have:

  • low LTV but fail affordability
  • high income but not enough deposit
  • strong deposit but too much monthly debt
  • clean credit but weak affordability
  • high LTV and still be approved
  • low LTV and still be declined

Both LTV and affordability need to work.

A large deposit can help, but it does not mean the lender will ignore income, outgoings or credit commitments.

LTV and first-time buyers

First-time buyers often have higher LTV mortgages because deposits are harder to save.

A first-time buyer may buy with:

  • 5% deposit and 95% LTV
  • 10% deposit and 90% LTV
  • 15% deposit and 85% LTV

Moving from 95% to 90% LTV can sometimes make a big difference to lender choice and rates.

But waiting to save more is not always the right answer.

First-time buyers need to balance:

  • buying sooner
  • monthly affordability
  • deposit size
  • emergency savings
  • property prices
  • rent costs
  • rate differences
  • fees
  • down-valuation risk

For more detail, read first-time buyer mortgages explained.

LTV and small deposits

A small deposit means high LTV.

That can still be workable, but it leaves less room for problems.

High-LTV buyers may be more exposed if:

  • property values fall
  • the property is down-valued
  • rates rise
  • affordability is tight
  • credit score is weaker
  • lender products are withdrawn
  • the property is harder to value
  • remortgage options are limited later

A small deposit can help someone buy sooner, but the risk needs to be understood.

For more detail, read how first-time buyers can get on the property ladder with a smaller deposit.

LTV and gifted deposits

A gifted deposit can reduce LTV if it increases the amount of money going into the purchase.

For example, if a buyer has a 5% deposit but family support helps them reach 10%, that may move the mortgage from 95% LTV to 90% LTV.

That can improve options.

But the gift needs to be declared and evidenced properly.

Lenders and solicitors usually need to know:

  • who is giving the money
  • whether it is a true gift
  • whether it must be repaid
  • source of funds
  • whether the giver will have any ownership interest
  • whether the gift affects affordability

For more detail, read gifted deposits for first-time buyers: what do lenders check?

LTV and home movers

Home movers often use equity from their current home as the deposit for the next property.

If your current property has increased in value, your equity may have grown.

If you have also repaid some of the mortgage, your LTV may have improved.

That can help when buying again.

For example:

Current home value:     £300,000 Current mortgage:       £180,000 Equity before costs:    £120,000 Current LTV:            60%

That equity may support the next purchase, depending on selling costs, deposit needed, affordability and the new property price.

LTV and remortgaging

LTV is very important when remortgaging.

Your LTV may improve over time if:

  • you repay the mortgage
  • you make overpayments
  • the property value rises
  • you borrow less
  • you reduce the mortgage balance

A lower LTV at remortgage can open better products.

For example, if you move from 85% LTV to 75% LTV, you may find more competitive options.

But the lender’s valuation matters.

Your estimated property value may not be the same as the lender’s valuation.

For more detail, read what is remortgaging and how does it work?

LTV and fixed-rate endings

When your fixed rate ends, LTV can affect the new deals available.

If your LTV has improved since you last fixed, you may have more options.

This can happen because:

  • you have repaid some capital
  • the property value has increased
  • you have made overpayments
  • your deposit/equity position is stronger

But if property values have fallen, your LTV may be worse.

That can make remortgaging harder or more expensive.

For more detail, read what happens at the end of a fixed-rate mortgage?

LTV and overpayments

Overpayments can reduce your mortgage balance.

That can improve LTV.

For example:

Property value:       £250,000 Mortgage balance:     £202,000 Current LTV:          80.8% After £3,000 overpayment: Mortgage balance:     £199,000 New LTV:              79.6%

That small change could matter if it moves you below an important LTV band.

Overpaying just enough to move into a lower band before remortgaging can sometimes be more useful than overpaying randomly.

But overpayment limits and early repayment charges must be checked.

For more detail, read mortgage overpayments: are they worth it?

LTV and down-valuations

A down-valuation can affect LTV.

If the lender values the property lower than the agreed purchase price, your LTV may become higher than expected.

For example:

Agreed price:       £300,000 Planned mortgage:   £270,000 Expected LTV:       90% Lender valuation:   £285,000 Mortgage:           £270,000 Actual LTV:         94.7%

That can create problems.

The lender may reduce the loan, change the product, ask for a bigger deposit or decline the application.

For more detail, read what happens if a property is down-valued?

LTV and negative equity

Negative equity happens when your mortgage is higher than the property value.

For example:

Mortgage balance: £190,000 Property value:   £180,000 Negative equity:  £10,000

This is more likely to be a concern where someone buys at high LTV and property values fall.

Negative equity can make it harder to sell, remortgage or move home.

It does not affect every high-LTV borrower, but it is a risk to understand.

LTV and buy-to-let mortgages

Buy-to-let mortgages often need lower LTV than residential mortgages.

Many buy-to-let lenders expect around 25% deposit or equity, meaning 75% LTV.

Some cases may need more deposit depending on:

  • rental income
  • property type
  • lender criteria
  • landlord experience
  • limited company ownership
  • credit history
  • HMO or specialist property
  • rental stress test
  • personal income
  • portfolio size

Buy-to-let is usually more deposit-heavy than standard residential borrowing.

For more detail, read buy-to-let mortgages explained.

LTV and residential vs buy-to-let mortgages

LTV works differently depending on whether the property is residential or buy-to-let.

A residential mortgage is usually assessed mainly against personal affordability.

A buy-to-let mortgage is assessed heavily against rental income and rental stress testing.

Both use LTV, but the lender’s view of risk is different.

For more detail, read what is the difference between a residential and buy-to-let mortgage?

How to improve your LTV before buying

You may be able to improve LTV before buying by:

  • saving a larger deposit
  • buying a cheaper property
  • using a gifted deposit
  • reducing other purchase costs
  • negotiating the purchase price
  • considering a smaller mortgage
  • waiting until savings improve
  • avoiding over-stretching
  • checking whether a scheme is suitable

The right strategy depends on whether your limiting factor is deposit, affordability or property price.

How to improve your LTV before remortgaging

You may be able to improve LTV before remortgaging by:

  • making overpayments
  • reducing the mortgage balance
  • checking the property value
  • avoiding extra borrowing
  • timing the remortgage carefully
  • reviewing whether you are near a lower LTV band
  • comparing product-transfer options
  • checking lender valuations

You do not always need to chase the lowest possible LTV.

The useful point is often crossing into the next pricing band.

Should you wait to reach a better LTV band?

Sometimes.

Waiting may make sense if you are very close to a better LTV band.

For example, if a small extra deposit or overpayment moves you from 90% to 85% LTV, it may be worth comparing the difference in rates, fees and monthly payments.

But waiting is not always better.

Property prices, rent, interest rates and personal circumstances can change.

The right answer depends on:

  • how close you are to the next band
  • rate difference
  • monthly payment difference
  • how long it will take to save
  • whether property prices may move
  • whether rent costs continue
  • whether affordability is already tight
  • whether waiting improves your overall position

A broker can help model the difference.

Why the lowest LTV is not always necessary

Lower LTV is usually helpful, but it is not always worth delaying too long.

For example, waiting years to move from 75% to 60% LTV may not be worthwhile if the rate difference is small and your housing need is immediate.

Likewise, using every pound of savings to lower LTV can leave you with no emergency fund.

A lower LTV is useful, but it should not come at the cost of financial resilience.

LTV and mortgage fees

LTV is only one part of the mortgage cost.

You should also compare:

  • product fee
  • valuation fee
  • legal fees
  • broker fee
  • cashback
  • early repayment charges
  • overpayment rules
  • total cost over the deal period
  • monthly payment
  • flexibility
  • approval likelihood

A lower rate at a better LTV band may still have a higher product fee.

Compare total cost, not rate alone.

LTV and credit history

LTV can interact with credit history.

A borrower with perfect credit may have more high-LTV options.

A borrower with credit issues may need a larger deposit because the lender sees more risk.

This may apply where there are:

  • missed payments
  • defaults
  • CCJs
  • debt management plans
  • bankruptcy history
  • high credit use
  • recent arrears

A bigger deposit does not erase credit problems, but it can sometimes improve lender choice.

For more detail, read can you get a mortgage with bad credit?

LTV and credit commitments

Credit commitments can also affect how useful your deposit is.

For example, a buyer may have a strong deposit but large monthly debts.

That may keep affordability tight, even at a good LTV.

Common commitments include:

  • credit cards
  • car finance
  • personal loans
  • student loans
  • childcare costs
  • maintenance payments
  • buy now pay later repayments

For related guidance, read can credit card debt affect your mortgage application? and can car finance affect your mortgage application?

How brokers use LTV

A broker may use LTV to compare which lenders and products are available.

They can help you understand:

  • current LTV
  • deposit needed for each band
  • rate differences between bands
  • whether waiting could help
  • whether overpaying before remortgage helps
  • whether fees outweigh rate savings
  • whether a down-valuation would cause problems
  • whether lender criteria change at higher LTVs
  • whether buy-to-let stress testing works

LTV strategy is often where big savings can be found.

It is also where some applications become stronger or weaker.

Common LTV mistakes

Avoid:

  • focusing only on the minimum deposit
  • ignoring the next LTV band
  • assuming all lenders use the same property value
  • confusing purchase price with lender valuation
  • using every penny of savings and leaving no buffer
  • assuming lower LTV fixes affordability
  • ignoring credit commitments
  • forgetting product fees
  • overpaying without checking early repayment charges
  • assuming property values always rise
  • ignoring down-valuation risk
  • not reviewing LTV before remortgaging

LTV is powerful, but it is only one part of the mortgage decision.

Simple LTV checklist

Before applying, ask:

  • what is my current LTV?
  • what deposit do I have?
  • what LTV band am I in?
  • how close am I to the next band?
  • would a slightly bigger deposit change the rate?
  • would an overpayment help before remortgaging?
  • what happens if the property is down-valued?
  • does affordability still work?
  • do I have enough savings left after completion?
  • are fees affecting the true cost?
  • does my credit history affect high-LTV options?
  • does buy-to-let need a lower LTV?
  • should I proceed now or wait?

These questions are more useful than simply asking, “Can I get the mortgage?”

Realistic example

Two buyers want the same £250,000 property.

Buyer A has a 5% deposit:

Deposit:  £12,500 Mortgage: £237,500 LTV:      95%

Buyer B has a 10% deposit:

Deposit:  £25,000 Mortgage: £225,000 LTV:      90%

Buyer B borrows less, may access more lenders, and may qualify for better rates.

Buyer A may still be able to buy, but the mortgage is likely to be more sensitive to affordability, credit score, valuation and market changes.

Same property.

Different LTV.

Different risk.

FAQs about loan-to-value

What does LTV mean on a mortgage?

LTV means loan-to-value. It shows the mortgage amount as a percentage of the property value.

How do you calculate LTV?

Divide the mortgage amount by the property value, then multiply by 100.

Is lower LTV better?

Usually, yes. A lower LTV can mean better rates, more lender choice and lower risk, although affordability still matters.

What is 90% LTV?

90% LTV means the mortgage is 90% of the property value and the deposit or equity is 10%.

What is 95% LTV?

95% LTV means the mortgage is 95% of the property value and the deposit is 5%.

What is 60% LTV?

60% LTV means the mortgage is 60% of the property value and the borrower has 40% deposit or equity.

Does LTV affect mortgage rates?

Yes. Mortgage rates often vary by LTV band, with lower LTV usually giving access to better rates.

Does LTV affect mortgage approval?

Yes. Higher LTV can mean stricter lender criteria, fewer products and more sensitivity to credit or affordability issues.

Can overpayments improve LTV?

Yes. Overpayments reduce the mortgage balance, which can improve LTV if the property value stays the same or rises.

Can a down-valuation affect LTV?

Yes. If the lender values the property lower than expected, your LTV may be higher than planned.

Bottom line

Loan-to-value is one of the most important numbers in a mortgage.

It shows how much you are borrowing compared with the property value.

A higher LTV usually means a smaller deposit, higher lender risk, fewer options and potentially higher rates.

A lower LTV usually means more equity, better product choice and stronger mortgage pricing.

But LTV is not the whole decision.

Affordability, credit history, property type, fees, mortgage term, income and future plans all matter too.

The smartest approach is to understand your LTV, check which band you are in, compare whether moving to a lower band helps, and avoid using every penny of savings without leaving a buffer.

Managing LTV well can improve your mortgage options when buying, moving or remortgaging.
