Choosing between a fixed, tracker or variable mortgage is one of the most important decisions you'll make as a first-time buyer. Each type works differently, and the right choice depends on your financial situation and risk tolerance.
In the UK, first-time buyers mainly have two mortgage types: fixed and tracker. A third option, variable, also exists but is less common. Understanding these options will help you pick the best deal.
What is a fixed-rate mortgage?
A fixed-rate mortgage locks in your interest rate for a set period, typically 2, 3, 5 or 10 years. Your monthly repayments stay the same throughout, making budgeting easy.
This is a popular choice for first-time buyers because it offers certainty. However, if interest rates fall, you won't benefit until your fixed term ends. Early repayment charges may apply if you switch before the term is up.
What is a tracker mortgage?
A tracker mortgage follows the Bank of England base rate, plus a set margin. If the base rate goes up, your repayments increase; if it goes down, they decrease.

Trackers can be cheaper initially, but they come with uncertainty. They suit buyers who can afford potential increases and believe rates will stay low or fall.
What is a variable-rate mortgage?
A variable-rate mortgage is set by the lender and can change at any time. It's often the default after a fixed or tracker deal ends.
Variable rates are usually higher than fixed or tracker deals, but they offer flexibility with no early repayment charges. However, your payments could rise unexpectedly.
Key takeaways for first-time buyers
- Fixed-rate mortgages offer stability and predictable payments, ideal for tight budgets.
- Tracker mortgages can be cheaper but carry the risk of rising repayments.
- Variable-rate mortgages are flexible but often more expensive and unpredictable.
- Consider your risk tolerance and future income when choosing.
- Use a mortgage broker or comparison site to find the best deal.
Comparison of mortgage types
| Mortgage type | Interest rate | Monthly payments | Risk | Best for |
|---|---|---|---|---|
| Fixed | Fixed for set period | Predictable | Low (during term) | Budget certainty |
| Tracker | Base rate + margin | Varies with base rate | Medium to high | Those who can handle fluctuations |
| Variable | Lender's discretion | Can change anytime | High | Flexibility |
How to choose the right mortgage for you
Start by assessing your financial situation. If you have a tight budget, a fixed-rate mortgage provides security. If you can afford higher payments and want to save money initially, a tracker might work.
Consider how long you plan to stay in the property. Fixed rates are good for long-term security, while trackers can be beneficial if you expect rates to fall.
Don't forget additional costs like arrangement fees and early repayment charges. A mortgage broker can help you compare deals and find the best fit.

FAQ
What is the difference between a fixed and tracker mortgage?
A fixed mortgage has a constant interest rate for a set period, while a tracker follows the Bank of England base rate, so payments can go up or down.
Is a fixed-rate mortgage better for first-time buyers?
It depends on your circumstances. Fixed rates offer stability, which many first-time buyers prefer, but trackers can be cheaper if rates fall.
Can I switch from a tracker to a fixed mortgage?
Yes, you can remortgage to a fixed rate, but check for early repayment charges on your current deal.
What happens after my fixed term ends?
You'll usually move to the lender's standard variable rate, which can be higher. You can remortgage to a new deal at that point.
Before committing, explore your options thoroughly. Many first-time buyers find it helpful to understand the broader financial landscape. For instance, learning about smart, standard or fixed energy tariffs can give you a sense of how fixed versus variable pricing works in other areas, which might inform your mortgage choice.
Government schemes can also ease the burden. The Help to Buy scheme has helped many first-time buyers get on the property ladder. Understanding these options can complement your mortgage strategy.
If saving a deposit is a challenge, consider that 100% mortgages have returned, offering no-deposit home loans for first-time buyers. These can be an alternative if you're struggling to save.
Finally, make the most of tax-efficient savings accounts. Comparing a First-Time Buyer ISA vs Lifetime ISA can help you grow your deposit faster while you decide on your mortgage.
