Ask most people what an interest-only mortgage is and they will describe the appeal easily enough: lower monthly payments, because you are only covering the interest, not the loan itself. Fewer people stop to think about what happens at the end of the term, when the whole amount borrowed falls due in one go. That gap in thinking caught a lot of borrowers out a decade or so ago, and it is why these mortgages went from being a default choice to something lenders now hand out far more carefully.
They have not disappeared, though. We still arrange interest-only lending regularly for landlords, retirees, and self-employed clients with a real plan for clearing the balance. It just is not handed out as freely as it used to be, and it is no longer assumed to be the default for anyone who simply wants lower payments.
Why Lenders Pulled Back
Before April 2014, interest-only was fairly easy to get, often on the strength of an assumption that rising house prices would cover the gap. The Mortgage Market Review changed that overnight. Lenders had to start checking for a credible, evidenced repayment plan, not just proof the monthly payment was affordable. Most mainstream lenders responded by scaling back hard on interest-only for ordinary residential borrowers, and that has not really reversed since.
Who Still Gets It
Buy-to-let sits outside most of this. Landlord mortgages are interest-only as standard, because the expectation from day one is that the loan gets cleared when the property is eventually sold or refinanced, not paid down month by month. Retirees have a separate product built for them, a retirement interest-only mortgage, where the loan gets settled when the home is sold, usually after death or a move into care rather than on a fixed date. Self-employed borrowers with irregular income can still get interest-only too, provided there is something concrete behind it — a pension, an investment portfolio, or a planned sale — and lenders want that written down rather than described in conversation.
First-time buyers rarely get a look-in here. Almost none arrive with a repayment vehicle already built, which is really the dividing line between this and the piece we wrote specifically about interest-only for first-time buyers.
The Numbers Behind the Decline
The scale of the fall is fairly stark. Industry data puts outstanding interest-only balances at roughly 3.2 million in 2012, dropping to somewhere close to 864,000 by 2023 — treat that as an approximate figure rather than an exact one, but the trend itself is well established.
What matters more right now is what comes next. Around 180,000 interest-only loans are expected to mature by 2027, and not everyone behind that figure has a repayment plan sorted. Lenders know this, which is why affordability gets checked periodically through the life of an interest-only loan, not only at the start.
A Live Regulatory Question
There is genuine movement on the rules at the moment, not just speculation. The FCA published flexibility guidance in December 2025 (FS25/6) and is running a live consultation, CP26/18, covering borrowers with irregular income, foreign currency mortgages, and applicants with credit issues. None of this signals a return to pre-2014 lending standards. It does mean affordability assessment at the margins is loosening slightly, worth knowing if you fall into one of those categories. Some see this as overdue help for people who do not fit a standard lending box; others see it as a workaround for house prices that have run ahead of wages.
Working It Out Properly
Working out your real affordability before settling on interest-only makes the decision far clearer. A broker can model both interest-only and full repayment side by side, so you can see the real difference in monthly cost, and weigh that against the risk of a lump sum still owing decades from now.
Is It Right for You?
For most homeowners, repayment mortgages remain the sensible default, because the balance genuinely shrinks and nothing is left owing at the end. Interest-only still has a role for buy-to-let, retirement lending, and self-employed borrowers with a proper plan behind them — it works less well as a general way to bring costs down for its own sake. The real question to put to a broker is not whether you can get one, but what your plan looks like on the day the term ends.
Frequently Asked Questions
What happens if I cannot clear the balance when an interest-only term ends?
You would likely need to remortgage, sell up, or release equity to settle what is owed, and none of those routes are certain to be there when you actually need them — markets shift, health changes, circumstances change. That is exactly why lenders want a credible repayment plan agreed upfront, and it is worth revisiting that plan every few years rather than taking it for granted.
Can first-time buyers take out an interest-only mortgage?
Very rarely, and only with a genuine repayment vehicle already in place. Most first-time buyers have not built up the kind of savings or investments lenders want to see earmarked for the balance. If interest-only is something you are considering as a first-time buyer, talk to a broker early — the choices genuinely narrow for this group.
Is interest-only automatic on a buy-to-let mortgage?
Most buy-to-let lending is written on an interest-only basis, but the lender still wants a plan for how the capital eventually gets repaid, usually through a sale or a refinance further down the line. It is generally easier to arrange than interest-only on a residential mortgage, though easier does not mean no questions get asked.
What does a lender actually accept as a repayment vehicle?
Something concrete and evidenced: regular payments into an ISA or investment account, a pension lump sum, or a documented plan to sell a particular asset, backed by real figures. A general intention to sell the house one day, without numbers behind it, will not satisfy most lenders.
How does a retirement interest-only mortgage differ from a standard one?
A RIO is built around later life specifically. You pay the interest each month for as long as you live in the property, and the loan itself gets settled when the home is eventually sold, most often following death or a move into long-term care rather than at a set date. It solves a different problem to a standard interest-only mortgage and is worth a separate conversation with a broker.
Is this a good moment to consider switching to interest-only?
That comes down to your own repayment plan far more than anything happening in the wider market. Lower monthly payments can genuinely help short-term cash flow, but switching without a genuine plan for repaying the capital just pushes the risk further down the line rather than getting rid of it. Worth talking through properly before deciding either way.
