What is an interest-only remortgage?

An interest-only remortgage is an interest-only mortgage that you take out after a previous interest-only mortgage. 

Borrowers often move their mortgage at the end of a fixed-rate period to avoid moving onto the lender’s Standard Variable Rate (SVR), which can often mean more expensive repayments. Or if you are already on an SVR, you might want to lock into a fresh interest-only mortgage to save money.

It may also be beneficial to remortgage on an interest only deal if your property’s value has increased because this enables you to access a lower loan to value (LTV) and a cheaper interest rate.  

Borrowers who have a lump sum could also pay off some of the capital on the loan to qualify for a lower LTV rate at remortgage.

If you want to take out more money against the property, perhaps for building improvements or developments, you could release cash through a remortgage.  

Interest-only remortgages are more readily available for higher value transactions, wealthier borrowers and buy-to-let investors.

How is an interest-only remortgage repaid?

Interest-only mortgages allow borrowers to repay just the interest on a mortgage during a set term with the capital repaid at the end of the loan. 

Lenders look for solid proof that the underlying capital can be repaid at the end of the term before granting a remortgage.

Acceptable methods of repaying the loan vary by lender but all will want to see that the strategy is credible. Depending on the risk of the repayment, some lenders may require higher income thresholds.

Interest-only repayment vehicles

Borrowers looking to remortgage interest-only loans will need to prove they have a credible plan to repay the underlying capital at the end of the term.

Below are some of the repayment vehicles that are accepted by lenders. 

Endowment policies

Lenders will be looking to see that the projected sum at maturity will need to be enough to cover the capital.

Stocks and shares

An investment portfolio can usually be used to repay the loan but there may be stipulations on the types of investments, for example, they may be restricted to the FTSE stock exchange and be based in the UK.

A stocks and shares ISA

An ISA can be part of an investment portfolio or standalone vehicle. Some lenders may require that the account has been held for at least 12 months.

Unit trusts

This is another type of investment that can be used as a repayment vehicle. Unit trusts can be used alongside other stocks and shares as part of an overall investment portfolio.

Investment bonds

These investments will need to be based in the UK and can be part of a wider investment portfolio.

Pension schemes

A percentage of retirement savings may be used if the overall projected fund is large enough.


Bonuses are accepted by some lenders. They will expect the capital to be paid off periodically.

Sale of a property 

Many lenders will permit you to sell the property to repay the mortgage as long as there is a certain level of equity in the home.

Is applying for an interest-only remortgage different to a repayment remortgage?

The normal lender criteria will apply to interest-only remortgages but lenders tend to have additional criteria that borrowers need to meet. 

Minimum income requirements are more stringent for interest-only, with the bar starting at around £40,000 a year. Depending on the repayment strategy, some lenders want to see as much as £100,000 a year.  

Furthermore, the loan-to-value ratios on offer are lower than with repayment mortgages. Some high street lenders require at least 50% equity in the property although LTVs of 75% are available.  

As a result, wealthier borrowers typically have more flexibility with interest-only loans and repayment strategies. 

However, the most important issue for lenders is that there’s good proof of repayment strategy that will ensure the borrower has the means to pay back the loan at the end of the term.

Interest-only remortgage FAQs

Will my interest-only repayment vehicle affect the remortgage terms I can get?

Yes, lenders will deem some strategies as riskier than others.

Is it a good idea to get an interest-only mortgage?

It depends on the individual circumstances of the borrower. 

How long does it take to remortgage?

Remortgages can take anywhere between four and eight weeks to arrange.

Can I apply for a remortgage in advance?

Yes, you can get a mortgage offer from a lender before you need it. Some remortgage offers last for several months.

It is always good to plan ahead and make sure you have an offer in place before your current deal ends so you don’t end up moving onto your lender’s standard variable rate.

Can I borrow more with a remortgage?

Yes, remortgage providers will usually let you borrow more than you owe on your property, particularly if your home has gone up in value. You can use the extra money for specific purposes like renovations.

The lender will want to know what the cash is for and will carry out affordability checks to make sure you can make the repayments comfortably.
