Choosing the right mortgage isn’t just about finding the lowest interest rate. The type of rate you choose, how you repay the loan, and the length of your mortgage term all affect what you’ll pay overall and how manageable your monthly payments will be.

Types of mortgage rates

Fixed rate mortgages

A fixed rate mortgage locks in your interest rate for a set period, typically 2, 3, 5, or 10 years. Your monthly payments stay the same regardless of what happens to market rates. Once the term ends, you’ll typically revert to your lender’s Standard Variable Rate (SVR) unless you remortgage.

Pros: Certainty and protection from rate rises. You know exactly what you’ll pay each month.

Cons: No benefit if rates fall, and most fixed deals have early repayment charges (ERCs) if you want to leave early.

Often suits: Those who want predictable payments, anyone stretching their budget, or people who value certainty over flexibility.

Tracker mortgages

A tracker mortgage follows the Bank of England base rate at a set margin above it. If the base rate is 3.75% (correct at 01.03.26) and your tracker is base rate plus 1%, you’ll pay 4.75%. When the base rate changes, so does your rate.

Pros: You benefit from rate cuts, and it’s transparent. Some trackers also come with no early repayment charges (ERC’s).

Cons: Payment uncertainty. If rates rise, so do your payments.

Often suits: Those who can afford payment flexibility or believe rates are likely to fall.

Standard Variable Rate (SVR)

The SVR is your lender’s default rate. Most borrowers end up here when their fixed or tracker deal ends. The lender can change it at their discretion, though it often moves in response to base rate changes.

Pros: No ERCs, so you can remortgage or overpay without penalty.

Cons: Usually expensive (often 2-3% higher than deal rates) and unpredictable.

Often suits: Those arranging a remortgage or planning to sell soon who need short-term flexibility.

Discount mortgages

A discount mortgage offers a set discount off the lender’s SVR for a fixed period. If the SVR is 7% and you have a 2% discount, you’ll pay 5%. Once the discount period ends, you revert to the full SVR.

Pros: Lower initial rate, and you benefit if the SVR falls.

Cons: Payment uncertainty and no base rate transparency.

Often suits: Less common now, but can work for those wanting a lower initial rate with some payment variability.

Offset mortgages

An offset mortgage links your savings to your mortgage. Instead of earning interest on your savings, the balance is offset against your mortgage debt. If you have a £200,000 mortgage and £20,000 in savings, you only pay interest on £180,000.

Pros: Tax efficient (no income tax on savings interest), flexible access to savings, and you pay off your mortgage faster.

Cons: Higher rates than standard deals, and benefits are minimal without significant savings.

Often suits: Higher-rate taxpayers, self-employed individuals with variable income, or anyone with substantial savings.

Types of repayment methods

Capital and interest (repayment mortgage)

Your monthly payment covers both the interest and a portion of the capital you borrowed. Over time, you gradually pay down the debt until you own the property outright at the end of the term.

Pros: Guaranteed repayment, builds equity, lower risk, and better rates.

Cons: Higher monthly payments than interest only.

Often suits: Most homeowners, particularly first-time buyers and those living in the property.

Interest only

You only pay the interest each month. The capital balance stays the same, and you need to repay it in full at the end using another method (sale of property, savings, investments, or other assets).

Pros: Lower monthly payments and freed-up cash flow.

Cons: No equity build-up, requires a credible repayment plan, and stricter lending criteria.

Often suits: More common in buy-to-let or for high-net-worth individuals. Considered specialist for residential borrowers.

Part and part

A hybrid approach where you repay part of your mortgage on capital and interest and part on interest only. For example, £200,000 on repayment and £100,000 on interest only.

Pros: Balance of affordability and debt reduction. Can help reduce payments whilst still reducing balance.

Cons: Still need a repayment plan for the interest only portion, and not all lenders offer this.

Often suits: Home movers stretching their budget or those with irregular income who still want to build equity.

Mortgage terms (number of years)

The mortgage term is how long you’ll take to repay the loan. Standard terms range from 5 to 40 years.

The longer the term, the lower your monthly payments, but the more interest you’ll pay overall.

Shorter terms mean higher payments but significant interest savings. Longer terms make mortgages more affordable month-to-month but cost more in the long run.

Extended terms (beyond age 70-75)

Most lenders cap terms at age 70 or 75, but some will lend beyond this under certain circumstances. Lenders assess your ability to repay into retirement by considering pension income, savings, and other provisions. There are also some special guarantor schemes designed to help older parents support younger children.

Pros: Access to borrowing later in life and lower monthly payments.

Cons: Stricter affordability checks and limited lender choice.

Often suits: Older borrowers with strong pension provisions or those planning to downsize.
