Understanding LTV (Loan-to-Value) and Its Impact on Your Remortgage

When you embark on the journey of remortgaging your home, you’ll encounter various financial terms and ratios. One crucial term to grasp is Loan-to-Value (LTV) ratio. Understanding LTV and its implications can significantly impact your remortgaging decisions and the deals available to you. In this article, we’ll break down the concept of LTV and shed light on how it influences your remortgage options as a homeowner.

What Is Loan-to-Value (LTV) Ratio?

In simple terms, the Loan-to-Value (LTV) ratio is a financial metric that measures the relationship between the size of your mortgage and the current value of your property. It is expressed as a percentage and is calculated as follows:

  • LTV Ratio (%) = (Mortgage Amount / Property Value) × 100
    For example, if your property is valued at £250,000, and your outstanding mortgage is £200,000, your LTV ratio would be:
  • LTV Ratio = (£200,000 / £250,000) × 100 = 80%
    This means your LTV ratio is 80%.

How Does LTV Affect Your Remortgage?

The LTV ratio plays a pivotal role in determining the terms, interest rates, and mortgage options available to you during a remortgage. Here’s how it impacts your remortgage journey:

1. Eligibility for Remortgage Deals

  • Lower LTV: A lower LTV ratio indicates that you have a substantial amount of equity in your property. Lenders typically view lower LTVs favorably, as they represent a lower level of risk. Consequently, you may have access to a broader range of mortgage deals and better interest rates.
  • Higher LTV: Conversely, a higher LTV ratio suggests a higher mortgage amount relative to your property’s value. This may limit your choice of remortgage deals and potentially result in less competitive interest rates.

2. Interest Rates

  • Lower LTV: Lenders often reward lower LTV ratios with lower interest rates. With more equity in your property, you are seen as a less risky borrower.
  • Higher LTV: Higher LTV ratios might result in slightly higher interest rates as lenders perceive greater risk due to the lower equity stake in your property.

3. Mortgage Affordability

  • Lower LTV: A lower LTV ratio can lead to more favourable affordability assessments, making it easier to secure a remortgage with your lender.
  • Higher LTV: Higher LTV ratios may require stricter affordability checks, as lenders may be cautious about lending larger sums to borrowers with less equity.

4. Equity Release Potential

  • Lower LTV: If your property’s value has increased over time, a lower LTV ratio may allow you to release equity through your remortgage for various purposes, such as home improvements or debt consolidation.
  • Higher LTV: A higher LTV ratio might limit your ability to release significant amounts of equity through your remortgage.

5. Deposit Requirements

  • Lower LTV: With a lower LTV ratio, you might need a smaller deposit, if any, when remortgaging.
  • Higher LTV: Higher LTV ratios may necessitate a larger deposit, which could impact your financial planning.


In summary, understanding the Loan-to-Value (LTV) ratio is fundamental when considering a remortgage. It’s a key determinant of the mortgage options available to you, the interest rates you’ll secure, and your ability to release equity from your property. As a homeowner, monitoring your LTV ratio and exploring strategies to lower it over time can empower you to make more informed remortgage decisions and potentially access more advantageous deals. Consulting with a mortgage adviser can also provide valuable insights into optimising your remortgage based on your LTV ratio and financial goals.
