Can’t Afford a Remortgage? What Happens Next

If you’re approaching the end of your current mortgage deal and you can’t afford the payments on a new remortgage, it can feel urgent. In the UK, lenders reassess affordability when you apply, and the figures can look very different from when you first took out your mortgage.

The key point is that “can’t remortgage” doesn’t automatically mean “no options”. What happens next depends on why affordability has become an issue and what flexibility you have with your mortgage balance, term and credit profile.

Why you might not be able to remortgage

Most remortgage difficulties come down to affordability, but there are several common triggers.

1) Affordability has changed

When you remortgage, the lender will want to be satisfied you can make the repayments based on your income, outgoings and the mortgage terms you’re requesting.

Affordability can be squeezed by:

• Higher interest rates compared with your current deal
• Increased living costs or reduced disposable income
• Changes in employment status or income type

Even if you’ve been paying your mortgage reliably, your affordability assessment may still fail if the new rate and payment amount push you beyond what the lender is comfortable with.

2) Your income proof no longer matches your original application

If your circumstances have changed since you took out your mortgage—for example, you’ve become self-employed or your income has become less predictable—lenders may require different evidence and longer trading history.

If you’re missing the right documentation, or your income can’t be evidenced in the way the lender needs, remortgage options can narrow quickly.

3) Your loan balance is too low (or you’re near the end of the term)

Some mortgages become difficult to remortgage when the remaining balance is below a lender’s minimum loan amount.

It’s also common for the final years of a mortgage to be less straightforward, particularly if your existing plan is nearing completion and the lender’s criteria don’t align with what you need.

4) Your credit history has worsened

Credit scores can change over time due to factors such as missed payments, increased credit usage, defaults, or administrative issues.

If your credit profile has deteriorated since your original mortgage, you may find that products you previously qualified for are no longer available.

5) Your loan-to-value (LTV) has increased

LTV is the relationship between your mortgage balance and the property value.

LTV can rise if:

• House prices fall in your area
• You’ve borrowed more than expected (for example, via additional borrowing)
• The mortgage balance hasn’t reduced as quickly as assumed

If your LTV is higher than a lender’s preferred range, you may need to bring additional equity or look at different product structures.

What to do if you can’t remortgage due to affordability

If the affordability issue is the main barrier, the next step is to identify what can be adjusted—either your mortgage terms, your income/outgoings picture, or the type of mortgage you’re seeking.

Consider holding off to improve affordability

In some situations, delaying the remortgage application for a short period can help.

This might mean:

• Stabilising income
• Reducing monthly commitments
• Preparing stronger evidence of income

Even a few months can make a difference if it allows your financial position to look more sustainable to a lender.

Adjust your mortgage term to reduce monthly payments

Extending the mortgage term can reduce the monthly repayment amount, which may help affordability.

However, it can increase the total interest paid over the life of the mortgage. It’s important to weigh the affordability relief against the longer-term cost.

Explore switching to an interest-only structure

If you’re struggling to meet repayments because the monthly amount is too high, an interest-only approach can sometimes reduce the immediate payment.

That said, interest-only mortgages are not a simple workaround. Lenders will usually want reassurance about how the capital will be repaid at the end of the term, and there may be additional equity and income requirements.

Improve your credit profile before applying

If credit has become an issue, improving it can broaden the range of lenders and products you can access.

Practical steps often include:

• Ensuring your details are accurate on your credit file
• Addressing any missed payments or outstanding issues
• Reducing credit utilisation where possible

If you’re planning to apply soon, it can be worth focusing on the items most likely to affect lender decisions.

Look at specialist lenders where appropriate

Where mainstream lenders decline because of affordability or credit profile, a specialist lender may be able to consider your circumstances differently.

The right approach is to match your facts to the lender’s criteria rather than repeatedly submitting applications that are unlikely to succeed.

Don’t overlook options with your current lender

Even if you can’t remortgage to a new deal elsewhere, your current lender may still provide alternatives.

Product transfer (staying with your current lender)

If you’re unable to remortgage externally, a product transfer with your existing lender can sometimes be available.

A product transfer may help you avoid moving onto the lender’s standard variable rate, depending on what options are offered at the time.

Manage the end of your deal carefully

If your current fixed or discounted period is ending and you’re not ready to remortgage, it’s important to understand what happens next with your mortgage payments.

In many cases, the mortgage will move to a different rate structure, which can increase monthly costs. Planning ahead can reduce the risk of being caught off guard.

Other options to consider (with caution)

Adding a guarantor

A guarantor mortgage can reduce the risk to the lender by adding another party who may be responsible for payments if you can’t meet them.

Because a guarantor takes on significant financial risk, it’s essential to fully understand the implications before going down this route.

Extending or changing the repayment strategy

Depending on your mortgage type and lender rules, there may be flexibility around how the mortgage is structured.

The most suitable option depends on your remaining term, property value, affordability and how you intend to repay the capital.

The most important next step

If you can’t afford a remortgage, the best outcome usually comes from understanding exactly what’s causing the affordability problem and then matching your options to that reason.

A structured review of your income evidence, outgoings, credit profile, LTV and remaining term can help clarify whether the solution is adjusting the term, exploring a different mortgage type, improving credit, or considering what’s available with your current lender.
