Buying a new home means that you must learn many new terms, and you will hear about loan-to-value as soon as you even begin your property search.
One of the factors that banks and mortgage lenders take into account in considering your mortgage application is your loan-to-value ratio. This represents the level of risk that the lenders are taking on by lending to you.
Your LTV may affect your chances of mortgage approval so it’s a good idea to get to know what it’s all about.

What is loan-to-value (LTV)?
The loan-to-value is the ratio between the amount of the loan or mortgage and the value of the property purchased.
Basically the higher your loan-to-value ratio, the more of your prospective property will be funded by a mortgage or borrowing rather than by your own funds.
How to calculate your loan-to-value ratio?
To calculate your loan-to-value, you will need to know the value of your intended property and the amount of the loan you will use to purchase the property.
To get your LTV, divide the property value by the mortgage amount and multiply by 100.
For example, if you purchase a property with a value of €250,000 with a loan of €200,000 then your LTV is 80% i.e. The amount of the loan is 80% of the value of the property.

How LTV affects mortgage rates.
As a general rule, if you have a lower LTV you will be more likely to be offered a more favourable mortgage interest rate.
Your mortgage interest rate will depend on several factors, such as your choice between a variable, fixed, or green mortgage, and whether you are a first time buyer, second or subsequent buyer, or a mortgage switcher.
Lenders provide information on their mortgage interest rates to give you an idea of the rate you may be offered.
How LTV has an effect on loan approval
Although several factors will be taken into account in determining whether your mortgage application will be approved, LTV has an effect on loan approval.
If you have a higher deposit, or a lower LTV, then you will in general be seen as a lower risk applicant and your loan is more likely to be approved.
Exceptions to the mortgage rules
There are limited exceptions, or exemptions, to Central bank lending rules. Every year, banks and mortgage lenders are allowed to lend a certain amount above the guidelines.
Lending above the limits is allowed depending on the type of buyer:
Exemptions can be made on the basis of loan-to-income (LTI) or loan-to-value (LTV) but not both.
Lenders also have different criteria around lending outside of Central Bank rules and how they use exemptions, such as the time of year they are available etc.
What is a ‘good’ loan-to-value ratio?
You will need to have a minimum deposit of 10% of the value of the property you intend to purchase.
Beyond this figure, the more you can save for a deposit the better as you may be seen as a ‘lower risk’ applicant when it comes to securing your mortgage as higher LTV ratios represent a higher risk to the lender.
If you can manage to save a 20% deposit, and your LTV is 80% or lower, then you may be eligible for a lower mortgage rate and better terms.
Loan-to-value ratio and remortgaging
If you wish to remortgage your property, this means that you wish to take out a new mortgage on your home and use this new loan to repay your existing mortgage, either at more favourable terms or to release equity in your home.
Borrowing additional money when remortgaging is known as releasing equity as you are, essentially, using the value of your home that you own as security to borrow a higher amount.
When remortgaging, you may borrow up to 90% in total of the value of your property.
How to improve your LTV ratio
If you wish to borrow at a lower loan-to-value, then you have several options.
Firstly, you could save more to pay a larger deposit, meaning that your mortgage will be for a lower proportion of the property value, i.e. you lower your LTV percentage.
Another option is to consider buying a more affordable property. This has two benefits as your LTV will be lower even though you have the same deposit, and you may also benefit from a lower mortgage rate.
If you already own a property and you renovate your property, or make alterations to lower the property’s BER, then you may also increase the value of your home. This may mean that your LTV is lower as the loan will be a lower proportion of the increased property value.
Can I take out a 100% mortgage?
Unlike in the past, lenders no longer offer 100% mortgages. Under the Central Bank lending rules, you must have a minimum deposit of 10% of the property’s purchase price to buy residential property.
There are Government schemes to help first time and fresh start buyers with the necessary deposit, such as the Help to Buy scheme, and the First Home Scheme.
If you are gifted a deposit or land from a parent or relative, rather than loaned, then many lenders will accept this and use it in calculating your LTV when applying for a mortgage.
