A loan-to-value ratio represents the ratio of the mortgage amount and the value of the property. It showcases how much risk the prospective mortgage borrower represents based on the loan amount and the appraised property value.
Generally, a lower LTV (Loan-to-value) ratio is better in the mortgage provider’s eyes. It means you are borrowing a smaller percentage of the property’s total value. It implies a larger down payment and low interest rates. Hence, you may get affordable monthly payments.
What aspects should you be familiar with for a loan-to-value mortgage?
Here is what you need to know:
- Loan-to-value is the proportion of the property’s value you borrow as a mortgage loan. For example, if you borrow £160,000 on a £200,000 home value, you borrow at 80% LTV.
- A high deposit on a mortgage reduces your LTV
- Higher LTVs make it harder to qualify for better interest rates and flexible loans, and vice versa.
- If the property is valued below the purchase price, the lender may base LTV on the lower valuation, which can push your LTV up.
- LTV can fall over time if your property value rises, which may help you remortgage onto a better deal.
What is a loan-to-value mortgage?
A loan-to-value mortgage is the amount you borrow against a percentage of the total property’s value. For instance, you borrow 80% of the property’s value if your loan-to-value ratio is 80%. If a property costs £300,000, you can borrow £240,000 with a deposit of £60,000.
When underwriting a mortgage, loan providers assess the risk they incur by analysing LTV. A higher risk of loan default is indicated when a borrower demands a higher LTV ratio. As a result, it could be difficult to get a mortgage. Alternatively, individuals with a lower LTV ratio may get a quick and affordable quote.
How to calculate a loan-to-value ratio on a mortgage?
You need to divide the amount borrowed by the property’s reviewed value to calculate a loan-to-value ratio. The loan providers generally express this ratio as a percentage.
For example, if you buy a home for £100,000 and pay £10,000 upfront, you borrow £90,000. Thus, your LTV is 90%. Here is the step-wise explanation of that:
- Step 1– Consider the home value to be £100,000
- Step 2– Subtract the deposit or upfront amount from home value = £100,000-£10,000 = £90,000 (mortgage amount)
- Step 3– Divide the mortgage amount by the property’s total value = £90,000 / £100,000 = 0.9.
- Step 4– Multiply the result by 100 = 0.9 x 100 = 90%.
Thus, the LTV ratio is 90%. It means you may borrow 90% of the property’s price as a mortgage amount. Use a free loan-to-value calculator in the UK for help.
What loan-to-value ratio should you aim for on a mortgage?
You should generally aim for 80% or less than 80% LTV for a mortgage. You may get 80% of the value as a mortgage loan. However, a 60-75% loan-to-value ratio is also ideal for better mortgage rates.
What is the lowest LTV available on a mortgage in the UK?
60% is the lowest loan-to-value ratio available on a mortgage in the UK for new mortgages and remortgages.
How does providing a small deposit affect your LTV?
A small deposit means you borrow a higher amount on a loan. It thus increases your liabilities for the loan-to-value ratio.
For example, if your home costs £250,000 and you put down just £5,000 as a deposit, you must borrow £200,000, which gives you a 95% LTV.
It presents more risk to the loan company. Thus, your mortgage options and chances of getting low-interest rates on personal loans online for a mortgage fall drastically.
Can I improve my Loan-to-value ratio on a mortgage? If yes, how?
Yes, definitely, you can improve the loan-to-value ratio on a mortgage by borrowing a lower amount of the total property’s value. Save for a higher deposit, renovate to boost the property’s value, improve your credit score, and negotiate a lower purchase price with the loan company.
Check whether you can overpay on your mortgage payments. It reduces overall interest costs, monthly payments and the total amount that you pay on the loan. You may also benefit from increasing the property’s price later. Then you can remortgage the current mortgage for a new, affordable interest rate and flexible terms.
Bottom line
A loan-to-value mortgage is the amount you borrow against the total value of the property. Borrowing a lesser amount of the property’s value helps you get better interest rates and terms, and vice versa. You may improve a property’s LTV by renovating the buyer-specific aspects to increase the property’s value, providing a higher deposit and improving the credit score. The higher the deposit, the lower the loan-to-value ratio and hence the liabilities.
FAQs
Is 75% a good loan-to-value for a mortgage?
Yes — 75% LTV is generally considered a good mortgage ratio because it means you have a 25% deposit, which lowers the lender’s risk and usually gives you access to more competitive rates. It is also comfortably below the 80% threshold that many lenders treat as a strong LTV band.
What are the benefits of a lower LTV?
A lower LTV means you borrow less as compared to the total price of the property. It results in low interest rates, cheaper monthly payments and grants you a higher portion of the property’s equity. It also helps you avoid costly insurance quotes.
Why does the LTV ratio matter to the mortgage providers?
The loan-to-value ratio helps the loan company analyse how much equity you hold in the property and how much of the property’s value you want to borrow as a mortgage. Accordingly, they decide the interest and the terms that you should be offered. It is generally ideal to borrow a lesser amount of the total property’s value for better terms.
Can your LTV change after you buy a home?
Yes, your Loan-to-value ratio may change after you buy a home. The change depends on how much you still owe on the loan and how much the property is worth now. Your LTV falls if you ensure consistent mortgage payments. Alternatively, it may fall if the value of the home rises and vice versa.
