What is fixed, and for how long?
A fixed-rate deal holds the interest rate for a specified period. That period is different from the full mortgage term. Ask what happens when the deal ends and what rate or arrangement would apply if you take no action. Do not assume the initial payment describes the cost for the entire life of the loan.
Variable rates need a closer description
A variable rate can change. The way it changes depends on the product: a tracker is linked to a specified reference rate under its terms, while a lender’s standard variable rate works differently. Read the actual illustration rather than treating every variable mortgage as interchangeable.
Compare the consequences for your budget
Consider how a different monthly payment would affect your household spending. Ask an adviser to explain several scenarios using the products you are considering. The question is not simply which rate appears lowest today, but how the commitment fits your finances and plans.
Look beyond the rate
Fees, early repayment charges, overpayment allowances and moving-home provisions can affect the usefulness of a deal. If you expect a significant change in circumstances, raise it before choosing. A product that looks attractive for someone staying put may not suit a person expecting to move soon.
Take these questions to the discussion
- How long does the initial rate arrangement last?
- What changes the rate, and how is that described in the contract?
- What is the total cost over the period being compared?
- What would it cost to leave or make extra repayments?
- What happens at the end of the deal?
This is a framework for comparison, not a forecast of interest rates or a recommendation of one mortgage type for every borrower.
