Q: Should you choose a fixed rate or a variable rate?

The two most common types of UK mortgage are the fixed rate mortgage and the variable rate mortgage. The essential difference is whether the interest rate can change during the life of the loan.

What is a fixed rate mortgage?

During the fixed-rate period the monthly payment normally stays the same and does not move with the Bank of England base rate. Fixed periods of two, three and five years are common in the UK market. When the fixed period ends, the borrower usually needs either to select a new product, by remortgaging or by taking a product transfer, or to move on to the lender’s standard variable rate (SVR).

What is a variable rate mortgage?

A variable rate moves with market rates, so the monthly payment may rise or fall, depending on the terms of the particular product.

Which suits an overseas buyer better?

There is no single answer. The decision should take account of the purpose of the purchase, how long you intend to hold the property, your cash flow planning, your tolerance for risk and the outlook for interest rates.

SJW Research & Intelligence analysis

Many clients focus on which lender offers the lowest rate, but what matters more is choosing a product that fits their long-term plans. Beyond the rate itself, it is worth looking at the length of the fixed period, the early repayment charge, the annual overpayment allowance and the flexibility to remortgage in future.

An SJW reminder

No mortgage product is inherently good or bad. What matters is whether it fits your asset allocation and your long-term plans. We suggest discussing the options fully with a licensed UK mortgage adviser before deciding.
