Quick Summary
Mortgage options break down into two main choices: how your interest rate moves (fixed-rate or tracker) and how you repay the capital (repayment or interest-only). Understanding these core differences helps you choose a mortgage that suits your circumstances and financial goals.
- Fixed-rate mortgages keep your payment the same for a set period, offering certainty but locking you in if rates fall.
- Tracker mortgages follow the Bank of England base rate, so your payment may change as rates move.
- Repayment mortgages pay down both interest and capital each month, whilst interest-only mortgages require you to repay the capital separately.
- Budget for arrangement fees, valuation fees, solicitor’s fees, survey fees and potential early repayment charges when comparing mortgages.
- First-time buyers with steady income typically benefit from a fixed-rate repayment mortgage as a starting point.

Understanding your mortgage options
When you’re buying a property or remortgaging, understanding your mortgage options is the first step toward making a decision you’re comfortable with. The choices you make now will affect your finances for years to come, so it’s worth taking time to understand what’s actually available to you.
The mortgage industry speaks in jargon, and it can be difficult to know where to start. Fixed rates, trackers, repayment, interest-only, the terminology piles up quickly.
The good news is that once you understand the core differences between mortgage types, the decision becomes clearer. You’re essentially choosing between two main variables: how your interest rate moves, and how you’ll pay back the capital. Get those two things straight, and everything else falls into place.
According to the Financial Conduct Authority’s consumer guidance, understanding your mortgage options before committing is essential for making informed financial decisions. This guide breaks down the main mortgage options in plain English, so you can work out what suits your situation.
Fixed-rate vs tracker mortgage: which suits your situation
A fixed-rate mortgage keeps your interest rate the same for a set period. Your monthly payment stays the same for the entire fixed period, regardless of what happens to interest rates in the market.
A tracker mortgage follows the Bank of England base rate. When the base rate rises, your rate may rise. When it falls, yours may fall too. Your payment may change accordingly.
The difference between them comes down to certainty versus flexibility. With a fixed rate, you know what your interest rate will be during the fixed period. You’re protected from rate rises during that period, but you’re also locked in if rates fall. Check the terms for any early repayment charge if you want to leave early.
A tracker can give you flexibility, but your payments may change as rates change. Consider whether you could manage payment changes and check the terms of the mortgage.
The choice depends on your circumstances and the terms of the mortgages available. Consider how you would manage changes to your payments.
The two main interest rate options work in fundamentally different ways.
| Mortgage type | Interest rate | Monthly payment | Best for |
|---|---|---|---|
| Fixed-rate | Stays the same for set period | Stays the same | Certainty and protection from rate rises |
| Tracker | Follows Bank of England base rate | May change | Flexibility as rates move |
Repayment vs interest-only mortgage: how each works
This is the other major decision: how you’ll actually pay back what you’ve borrowed.
A repayment mortgage means you pay back both the interest and a portion of the capital each month (Borrowers with an interest-only mortgage should act now). If you make the required payments throughout the mortgage term, the capital is repaid by the end of the term.
An interest-only mortgage means you pay interest without paying down the capital through those payments. The capital remains outstanding and is due under the mortgage terms. Consider how you would repay it.
Interest-only payments do not pay down the capital. Consider how you would repay the outstanding amount when it is due, and check the lender’s requirements.
With a repayment mortgage, payments go towards both interest and capital. The amount of capital outstanding reduces as it is repaid.
The difference comes down to the payment structure and, for an interest-only mortgage, how you plan to repay the outstanding capital. Check the lender’s criteria and consider whether the mortgage suits your circumstances.
Mortgage costs and fees you need to budget for
When comparing mortgage options, consider the interest rate and any other costs that apply.
Arrangement fees may be charged by a lender when setting up a mortgage. Check the mortgage terms for any fees and compare the overall cost.
Valuation fees may apply for a lender’s valuation of the property. Check what the lender’s valuation involves and whether a fee applies.
Solicitor’s fees cover legal work associated with a property purchase. Ask for a quote for the work required.
Survey fees may apply if you choose to commission a survey. Ask the surveyor what the survey covers and request a quote.
Early repayment charges may apply if you repay your mortgage early or change deals. Check your mortgage terms for details.
The key is to add all these costs together when comparing mortgages. A mortgage with a lower interest rate might have higher fees, making it less attractive overall. That’s why the FCA’s mortgage comparison guidance recommends looking at the total cost, not just the rate.
Using a mortgage affordability calculator to find your range
A mortgage affordability calculator can provide an estimate of how much you might be able to borrow.
The amount a lender may offer depends on its assessment of your circumstances. A calculator can provide an estimate, but it does not establish your borrowing limit or property budget.
An affordability calculator may ask about your outgoings and commitments. Lenders assess affordability using their own criteria.
A calculator provides an estimate, not a guarantee. A lender will carry out its own assessment.
Using a mortgage affordability calculator to find your range walks you through the process step by step.
Choosing the right mortgage option for your circumstances
The mortgage option that suits you depends on your circumstances, including your income, deposit, other debts and preference for certainty or flexibility.
If you’re a first-time buyer with a steady income: A fixed-rate repayment mortgage is usually the safest starting point. You know your payment won’t change, you’re building equity, and you’re not taking on unnecessary complexity. Once you understand how mortgages work, you can explore other options.
If you’re self-employed or your income varies: Lenders are more cautious with variable income. A fixed-rate mortgage removes one variable from the equation. Some lenders specialise in self-employed mortgages and understand your circumstances better than high street banks do. This is where working with a mortgage adviser who knows self-employed lending becomes valuable.
If you’re remortgaging and rates have fallen: You might switch from a higher fixed rate to a lower one. The maths usually work out clearly in your favour. But check the early repayment charges on your current deal, sometimes they’re substantial enough to offset the savings.
If you have substantial savings or investments: An interest-only mortgage might make sense, particularly if your investments are growing faster than your mortgage interest rate. But this requires discipline, you need to stick to your repayment plan.
When comparing mortgages, consider the interest rate alongside any fees that apply.

Frequently Asked Questions
What are the main types of mortgage options available?
The main mortgage options split into two categories: how the interest rate works (fixed-rate or tracker) and how you repay (repayment or interest-only). A fixed-rate mortgage keeps your interest rate the same for a set period, while a tracker mortgage moves up and down with the Bank of England base rate. With repayment mortgages, you pay off the loan gradually over the term. Interest-only mortgages mean you only pay interest each month, with the capital due at the end.
What is the difference between a fixed-rate and tracker mortgage?
A fixed-rate mortgage keeps your interest rate the same for a set period. A tracker mortgage follows the Bank of England base rate, though the terms of individual mortgages can vary. Check the mortgage terms to understand how your rate and payments may change.
How do repayment and interest-only mortgages work?
With a repayment mortgage, your monthly payment covers both interest and a portion of the capital borrowed. Over the mortgage term, you gradually pay off the entire debt. By the end, you own the property outright. An interest-only mortgage means you pay only the interest each month; the capital remains outstanding and is due in full when the mortgage ends. You need a separate repayment plan (such as savings or an investment) to pay back the capital.
What mortgage costs and fees should I budget for?
Mortgage costs may include fees in addition to the monthly payment. Check the mortgage and purchase terms for any fees that apply, and consult the official government source for current Stamp Duty Land Tax information.
How can a mortgage affordability calculator help me?
A mortgage affordability calculator can provide an estimate, but it does not determine how much a lender will offer. Actual affordability depends on your circumstances and the lender’s assessment.
I’m self-employed, how do lenders view my mortgage application?
Lenders assess self-employed applicants according to their own criteria. Requirements can vary, so check with the lender what information it needs. Andrew Westwood Mortgages provides personalised advice to self-employed individuals navigating mortgage applications and searches a wide range of lenders.
