Interest-only mortgages have been making a comeback – and this time there’s a big focus on helping first-time buyers. It became much harder for first mortgage seekers to get interest-only mortgages after the 2008 economic crash, but things have gradually been evolving and you may well be able to now secure one in 2025 if you’re a first-time buyer with a larger deposit.
If you’re ready to find out more about the pros, cons, risks and why this change is so important for many first time buyer mortgages in the United Kingdom, then read on.
Why Have Interest-Only Mortgages Come Back?
Until recently, interest only mortgage deals were out of reach for most non-buy-to-let borrowers. The financial crash in 2008 meant lenders became much more cautious about this kind of borrowing. Affordability stress tests have been loosened by the FCA and this has encouraged now lenders to reintroduce more flexible options. This means interest-only mortgages aren’t just for landlords and similar investors anymore, they’re increasingly accessible for first-time buyers.
Mortgage lenders are becoming more flexible with interest-only mortgages as they recognise that not every borrower needs a full repayment deal, especially if they’re likely to relocate in a few years. For some first-time buyers, interest-only borrowing can be a smart short-term solution that frees up monthly cash without them having to commit to a long-term repayment agreement.
The key difference between today’s interest-only mortgages and those of the past is accountability. Lenders now expect to see a clear, credible repayment strategy right away, and borrowers need to take a more proactive approach to planning how they’ll repay the loan at the end of the term.

What Are the Benefits of Interest-Only Mortgages for First-Time Buyers?
As you’ll only be paying the interest on the loan, your monthly outgoings will be lower so you can free up cash. As the balance won’t be going down, you can clear it by selling your property later or with another repayment plan.
When you’re making lower payments than you would with a traditional mortgage, you might qualify for a bigger loan or be able to buy a better property than you normally would. The extra funds you’ll have access to due to an interest-only mortgage can be used for things like home improvements, savings and investments.
What Are the Disadvantages of Interest-Only Mortgages for First-Time Buyers?
You will need a firm plan to repay the money once the mortgage term ends as you’ll still owe the full amount that you originally borrowed. You could be in trouble if you can’t pay it back. These mortgages can also be more expensive over time if you’re paying more interest than you otherwise would.
Lenders also tend to have stricter criteria when it comes to interest-only loans. You’ll normally need a minimum deposit of at least 20-25%, income of £50,000 or more and proof that you’ll be able to repay the money at the end of the term. If you want to use your property or other investments to repay, you could find yourself in trouble if these don’t see as much growth as you expect.
Creating a Strong Repayment Strategy for an Interest-Only Mortgage
If you want to apply for an interest-only mortgage, you’ll need a solid plan that you can show lenders upfront.
You may plan to use:
- Savings or Investments
This means building up enough money over time using savings accounts, ISAs, shares or a pension. These can ensure you’ve got a lump sum to clear the debt at the end.
- Rising Property Values
Some buyers expect their homes to increase in value so they can sell them later and use the profit to pay off the mortgage. Although this can work, nothing is guaranteed when it comes to future property values. You may also plan to remortgage once the deal ends.
Another option could be to opt for a hybrid mortgage, paying off some of the loan gradually and the rest at the end of the term. This can reduce the final lump sum you pay. Hybrid mortgages are often also referred to as “Part and Part Mortgages” – as part of the mortgage is interest only and part is capital repayment.
Whatever the case, lenders will want to see a realistic and achievable plan, not something that’s mainly based on hope.

Should I Consider an Interest-Only Mortgage as a First-Time Buyer?
An interest-only mortgage is more likely to be right for you if you’ve got a large deposit of at least 20-25%. You’ll need a strong repayment plan and to clearly understand the terms. It may not be the best solution if your repayment plan isn’t convincing enough, you’re relying on uncertain market growth and you don’t want the pressure of finding a large sum by the end of the agreement.
How a UK Mortgage Broker Can Help
Getting an interest-only mortgage when you’re a first time buyer can be complicated. You’ll have stricter eligibility rules to meet, a smaller range of deals and more risk if you get it wrong. This is why so many first time borrowers are using UK mortgage brokers to get the right deals for their specific needs.
One of the best reasons for getting help from a mortgage broker is that they work for you rather than the bank. They can examine the entire market and find lenders who don’t usually advertise to the public. This helps them to find deals which are right for your deposit size, your income and your long-term plans. The best mortgage brokers know which lenders are currently accepting interest-only first-time buyer applications, and they know which types of repayment strategies lenders are likely to accept.
Another great reason for using a mortgage broker when you need an interest-only mortgage as a first-time buyer is they can help you curate all the essential documents that you’ll need to impress lenders. They will use their experience and expertise to present your application in a way that matches all lender expectations. This will boost your chances of being approved.
Interest-only mortgages are less common than standard repayment deals, so it can really help to have an expert on your side who can explain all the terms to you clearly to prevent confusion. Their help can prevent you from missing out on the best deals or being stuck with an unsuitable agreement. When you use a broker, you have a great chance of getting the ideal mortgage for your situation.
