How Does a Student Loan Affect Your Remortgage?
A student loan affects your remortgage primarily through its impact on your monthly disposable income. Lenders carry out affordability assessments to ensure you can comfortably meet your mortgage repayments, and student loan repayments are treated as a committed monthly outgoing that reduces the income available for mortgage payments.
Unlike other forms of debt such as personal loans or credit cards, student loans are repaid as a percentage of your earnings above a certain threshold. This means your repayment amount increases as your salary rises, which lenders take into account when calculating how much you can borrow.
The impact on your borrowing capacity can be significant. For example, if you earn 35,000 pounds per year and are on Plan 2, your monthly student loan repayment would be approximately 98 pounds. Over the course of a year, that reduces your assessed income by nearly 1,200 pounds, which could reduce your maximum borrowing by around 5,000 to 5,400 pounds based on typical income multiples.
However, it is important to put this into perspective. Student loan repayments are generally lower than repayments on equivalent amounts of unsecured debt, and lenders understand this. Most lenders treat student loans less severely than credit card debt or personal loans when assessing affordability.
Your student loan does not appear as a debt on your credit report in the way that credit cards and personal loans do. It is collected through the PAYE system for employed borrowers, which means lenders see it as a deduction from your salary rather than an outstanding debt obligation.
Student Loan Repayment Plans and How Lenders Treat Them
The UK student loan system has several different repayment plans, each with different thresholds and repayment rates. Understanding which plan you are on is important because it affects the amount of your monthly repayment and therefore your affordability assessment.
Plan 1 applies to students who started their course before September 2012 in England and Wales, or who took out loans in Northern Ireland or Scotland. Repayments are 9% of income above the current threshold. The balance is written off after 25 years or when you reach 65, depending on when you took out the loan.
Plan 2 applies to students who started their course on or after September 2012 in England and Wales. Repayments are also 9% of income above the threshold, but the threshold is higher than Plan 1. The balance is written off after 30 years.
Plan 4 applies to Scottish students who took out loans on or after September 1998. Repayments are 9% of income above the Scottish threshold.
Plan 5 applies to students starting courses from August 2023 in England. Repayments are 9% of income above the threshold, and the balance is written off after 40 years.
Postgraduate loans are repaid at 6% of income above a separate threshold, in addition to any undergraduate loan repayments you may be making.
Most lenders calculate your student loan repayment based on the plan type and your current salary, then deduct this from your income when assessing affordability. Some lenders are more generous than others in how they treat these deductions, so comparing lender approaches through a broker can be beneficial.
How Much Can You Borrow With a Student Loan?
The amount you can borrow when remortgaging with a student loan depends on several factors, including your salary, the repayment plan you are on, your other financial commitments and the specific lender's affordability model.
To illustrate the impact, consider two borrowers who both earn 40,000 pounds per year. One has no student loan, while the other is on Plan 2. The borrower with the student loan has monthly repayments of approximately 136 pounds, or roughly 1,632 pounds per year. Using a standard income multiple of 4.5 times, the borrower without a student loan might be offered up to 180,000 pounds, while the borrower with a student loan might be offered around 172,000 to 175,000 pounds.
While this reduction is noticeable, it is usually manageable and should not prevent you from remortgaging in most circumstances. The impact is proportionally smaller for higher earners and those with more equity in their property.
There are steps you can take to maximise your borrowing capacity despite having a student loan. Reducing other debts such as credit cards and personal loans will free up more of your assessed income. Building more equity in your property through overpayments or capital growth will improve your loan-to-value ratio and open up better rates.
Some lenders take a more favourable view of student loans than others. A few lenders may not fully deduct student loan repayments from your income, or may use a more nuanced calculation that considers the fact that student loans are written off after a set period. Working with a broker who understands these differences can help you find the lender offering the highest borrowing capacity for your circumstances.
If you are close to paying off your student loan or close to the write-off date, it may be worth discussing this with your broker as some lenders may take a more lenient view of repayments that are due to cease in the near future.
