Key Facts About Student Loans and Mortgages

When applying for a mortgage, your student loan will be considered as part of your overall financial assessment, but it works differently than other types of debt:

Student Loans vs. Traditional Debt

  • Income-contingent repayments: Unlike traditional loans with fixed monthly payments, student loan repayments are based on your income
  • Not on your credit file: Student loans don't appear on your credit report and don't directly affect your credit score
  • Considered as committed expenditure: Mortgage lenders view your student loan repayments as a monthly commitment that reduces your disposable income

Impact on Borrowing Amount

Your student loan primarily affects your mortgage application in one key way: it reduces how much you can borrow because:

  • Your monthly student loan repayments reduce your disposable income
  • Lenders typically use income multipliers (e.g., 4.5 times your annual income) but adjust downward based on commitments
  • A student loan won't typically cause a mortgage rejection, but it may limit how much you can borrow

Important Note

Unlike credit card debt or personal loans, paying off your student loan early won't necessarily improve your mortgage eligibility unless doing so would take you below the repayment threshold.

How Affordability Assessments Work

Mortgage lenders perform detailed affordability assessments to determine how much they're willing to lend you:

What Lenders Look At

  • Income: Your basic salary plus any regular bonuses or additional income
  • Commitments: Including student loan repayments, other loan repayments, credit card payments, childcare costs
  • Essential spending: Bills, food, transport, and other necessary expenses

How Student Loan Repayments Factor In

When assessing your student loan impact:

  • Lenders look at your actual monthly student loan repayment amount from your payslips
  • This amount is deducted from your income when calculating how much you can afford to repay on a mortgage
  • The higher your student loan repayment, the more it reduces your mortgage borrowing potential

Example Calculation

For a Plan 2 borrower earning £35,000 per year:

  • Monthly student loan repayment: Approximately £57 per month
  • Annual reduction in mortgage borrowing potential: Approximately £3,000 to £4,000
  • This is because the £57 monthly commitment could otherwise support additional mortgage borrowing

Maximizing Your Chances of Mortgage Approval

Steps to Take Before Applying

  1. Check your payslips: Understand exactly how much you're currently paying toward your student loan
  2. Reduce other debts: Pay down high-interest debts like credit cards and personal loans
  3. Save for a larger deposit: A bigger deposit often means more favorable lending terms
  4. Check your credit score: Fix any issues on your credit report before applying
  5. Stabilize your income: Lenders prefer applicants with stable employment history

Consider Joint Applications

If applying with a partner who doesn't have a student loan:

  • Your combined affordability assessment may be stronger
  • The impact of your student loan is diluted by the additional income
  • You may be able to borrow more than you would individually
