Mortgage review

Interest-only mortgage: review your repayment plan

Connect the mortgage balance, maturity date and repayment assets in one practical review, rather than focusing only on the monthly payment.

Separate interest payments from the debt

Interest-only payments cover interest rather than gradually clearing the borrowed capital. The capital still needs repaying. MoneyHelper explains why the borrower needs a credible repayment plan and should review whether it remains on track.

  • Find the current balance and the contractual maturity date.
  • Identify any repayment and interest-only parts separately.
  • Record the repayment method you originally intended to use.

Make an evidence map

Create a list of each asset or source that forms part of the plan. This is an organisation exercise for a discussion with the relevant professionals, not a valuation or an investment recommendation.

  • Record ownership, the statement date and the value shown.
  • Note when funds can be accessed and any known restriction.
  • Flag assets also needed for retirement, another loan or household spending.

Challenge the assumptions

An investment value or expected sale price is not a guaranteed future repayment amount. Ask the appropriate financial, tax or legal adviser to explain uncertainties and any cost of making funds available.

  • Compare the mortgage balance with the plan using clearly dated figures.
  • Ask what happens if the expected amount is lower or arrives later.
  • Avoid counting a hoped-for bonus, inheritance or price rise as certain.

Agree actions and the next review

If the plan appears insufficient, contact the lender and seek advice early. MoneyHelper describes discussing options such as overpayments or changing the repayment basis; availability and costs need checking for the individual mortgage.

  • Write down the questions to put to your lender and adviser.
  • Record any charges or conditions before making a change.
  • Set the next review date and identify which information must be refreshed.

Bring to the first conversation

  • Current statement, repayment basis and maturity date
  • A dated list of intended repayment assets
  • Access restrictions and competing uses for those assets
  • Questions about a shortfall, delay or change of plan

Your questions, answered

Does switching to a new rate solve the repayment issue?

A new rate can change the cost of borrowing, but it does not itself provide the money to repay the capital. Keep the rate review and the repayment-plan review connected.

Can Jack recommend which investments I should hold?

This guide concerns mortgage preparation. Investment, pension and tax recommendations require the appropriately authorised or qualified professional; clarify each adviser’s scope.

What if the mortgage ends soon and the plan is short?

Contact your lender promptly and explain the position. Do not assume an extension, refinance or sale will be available on the terms or timetable you need.
