If you’ve graduated university in the last few years and you’re now saving for your first home, you may be seriously considering your finances and wondering if you can get a mortgage with your student loan debt.
Yes, you can get a mortgage with student loan debt alone. A lot of first-time buyers in the UK have a student loan, and lenders are entirely used to seeing them on an application. But there are some situations where this is less straightforward…
In this blog, find out how student loans mortgage decisions work to help you plan your purchase with confidence.
Can you get a mortgage with student loan debt?
Yes, you can get a mortgage with student loan debt in the vast majority of cases. It’s genuinely one of the most common financial circumstances lenders see from first-time buyers. However, complications may arise if you’re paying a significant chunk of your loan back monthly.
Ultimately, what matters far more to a lender is the whole picture: your income, your deposit, your credit history and any other loans you’re carrying.
Does student loan affect mortgage affordability?
Yes, having a student loan does affect your mortgage affordability. The amount you repay monthly results in you having less disposable income; therefore, you can normally borrow less. The good news is that lenders have their own discretion over whether the amount you pay per month affects the amount you can borrow.
Unlike a credit card or a car finance agreement, your student loan isn’t reported to credit reference agencies, so it won’t drag down your credit score. Lenders don’t treat it as “bad debt” in the way they treat missed payments or high credit utilisation. The payment does however show on your payslip and is taken automatically once your income reaches a certain level, therefore you will not ever miss a payment.
However, when a mortgage lender works out how much you can borrow, they don’t just look at your salary – they look at what’s left after your regular outgoings. Your monthly student loan repayment is treated as a committed expense, in the same bracket as rent, childcare or a car payment. The more that comes out of your pay packet each month, the less disposable income you appear to have, and the less a lender may be willing to offer.
A few things tend to reassure lenders further:
- A clean credit history with no missed payments elsewhere
- A larger deposit, which reduces your loan-to-value and often unlocks better rates
- Low or no other unsecured debt, such as credit cards or car finance
- Stable, verifiable income, whether employed or self-employed
How much could a student loan reduce your borrowing?
The size of the impact depends entirely on your monthly repayment, not your total balance. Lenders are largely uninterested in whether you owe £15,000 or £55,000. What matters is the figure coming off your payslip each month.
That figure depends on which repayment plan you’re on. For the 2026/27 tax year, the repayment thresholds are:
- Plan 1: £26,900 a year
- Plan 2: £29,385 a year
- Plan 4 (Scotland): £33,795 a year
- Plan 5: £25,000 a year
- Postgraduate Loan: £21,000 a year
Above these thresholds, you repay 9% of the excess (6% for a Postgraduate Loan). A graduate on Plan 2 earning £35,000 repays around 9% of £5,615. That works out at roughly £42 a month, which might only trim borrowing capacity by a few thousand pounds. A graduate on Plan 5 has a lower £25,000 threshold, so the effect can be bigger. Someone repaying two loans at once could see a bigger reduction, sometimes into the tens of thousands, depending on income and the lender’s calculation method.
If you’re weighing up whether to use savings to clear your student loan before applying, it’s not always recommended, as most Plan 2 and Plan 5 balances are written off after 30 to 40 years, regardless of what’s still owed. Overpaying doesn’t usually improve your financial position and a larger deposit almost always does more for your mortgage options than eliminating the loan itself.
Although the above does not constitute as advice and is generic information, please do not use it when making a decision about applying for a mortgage as it’s always best to talk to a professional mortgage adviser as every lender has different criteria and will allow certain thresholds of debt before it will affect the amount you can borrow.
Do you have to declare student loan on mortgage application?
Yes, whether you’re applying directly or through a broker, you’ll need to declare your student loan repayment as part of your outgoings, in the same way you’d declare a personal loan. This is usually a simple case of entering your monthly repayment amount, which the underwriter will then verify against your payslips.
If you’re employed, this is straightforward – your payslip shows the deduction each month. If you’re self-employed, lenders will instead look at your SA302 tax calculations and Tax Year Overview from HMRC, since your repayment is collected through Self-Assessment rather than PAYE.
However, if your income currently sits below your repayment threshold, you won’t have anything to declare because nothing is being deducted. Should your income later rise above the threshold, repayments will kick in, but this won’t retrospectively affect a mortgage you’ve already secured. Most lenders won’t penalise you for a rise in earnings that also increases your student loan repayment.
What if you have more than one student loan?
Plenty of graduates repay more than one loan at once, typically an undergraduate Plan 2 or Plan 5 loan alongside a Postgraduate Loan for a master’s or doctorate. If that’s your situation – both repayments are deducted once you’re above each threshold. This can mean up to 15% of your income above the relevant bands going out before affordability is even considered. This is coupled with the fact that the lender may look favourably on this because they know your earning capacity in the future could rise more, and more quickly.
It’s still workable, but it’s another reason to get advice early rather than rely on a lender’s online calculator. A broker can model your actual take-home position and point you towards lenders whose criteria won’t unfairly penalise you for having studied further.
If your income sits close to a lender’s usual limits, a joint mortgage application is also worth raising with your adviser. Buying with a partner adds a second income to the assessment, which can offset the effect of your student loan repayments on overall affordability.
How a mortgage broker can help with student loan debt
It’s beneficial to have someone comparing the market for you as different lenders calculate the impact of student loan repayments differently. Some deduct your exact monthly repayment from your income.
Working out how much you can borrow yourself can be confusing and time-consuming, especially when lenders don’t all treat student loan repayments the same way. A broker who knows which lenders treat student loans most favourably can make a genuine difference to how much you’re offered.
