What Large Equity Means for Your Remortgage Rate
Mortgage rates are tiered by LTV, and the best rates are consistently reserved for the lowest LTV bands. At 60% LTV — corresponding to 40% equity — borrowers typically access rates at or very close to the best the market offers. Below 60% LTV, some lenders offer marginally better products, but the difference between the 60% LTV tier and the 50% or 40% LTV tiers is usually small.
The difference between 60% LTV rates and 75% or 80% LTV rates is meaningful. On a £300,000 outstanding balance, a rate difference of 0.5 percentage points amounts to £1,500 per year in additional interest. Over a five-year fixed term, that is £7,500 in extra cost. The rate advantage of holding large equity is not trivial, and it compounds over the remaining life of the mortgage.
For borrowers at LTV ratios of 50% and below, the rate differential from the 60% LTV tier narrows, but some lenders do offer dedicated products for sub-50% LTV borrowers. These products are often available only through brokers and represent the very best pricing in the mortgage market. If your LTV is below 50%, it is worth specifically asking a broker about whether any lenders offer enhanced rates at this level for your particular circumstances.
It is also worth noting that with large equity, you have flexibility over how much of your equity to retain versus release. If your priority is the absolute lowest rate, you will want to keep your LTV as low as possible. If you want to release equity for a specific purpose — funding a home improvement, helping a family member buy a property, or consolidating debts — you can raise your LTV somewhat while still accessing very competitive rates, as long as the new LTV remains in a favourable tier.
Releasing Equity When You Have a Large Amount
With significant equity in your property, equity release through a remortgage is one of the most cost-effective ways to access a substantial sum. Remortgaging to release equity means increasing your outstanding mortgage balance — borrowing more against your property's value — and receiving the additional sum as a lump payment. The rate you pay is a mortgage rate rather than a personal loan or credit card rate, which for large sums represents a significant cost saving.
Common reasons to release equity through a remortgage include funding home improvements and extensions, providing a deposit or financial support for children buying their own properties, consolidating higher-rate debt into a single lower-rate payment, and funding significant life expenses such as a wedding, education costs, or travel. In each case, the low cost of mortgage borrowing relative to other credit types makes equity release an attractive option for those with sufficient equity available.
The key constraint on equity release through remortgage is affordability — the lender will assess whether you can comfortably service the increased mortgage balance on your current income. Large equity does not automatically override affordability requirements, though it does mean you remain in favourable LTV territory even after releasing a substantial sum. For example, a borrower with a property worth £500,000 and an outstanding mortgage of £150,000 could release £100,000 and still have an LTV of only 50% — well within the best rate tiers.
It is important to consider the long-term cost of releasing equity. While the rate is low, extending the borrowing over a mortgage term means the total interest paid on the released sum can be substantial. Comparing the total cost of equity release against alternative funding options — and considering whether a shorter repayment term for the released portion is feasible — is a worthwhile exercise that a broker or independent financial adviser can help you work through.
