Understanding Core Mortgage Types

What is a Fixed-Rate Mortgage?

Fixed-rate mortgages offer interest rate stability:

• Rate remains constant for a set period (typically 2-5 years)
• Payments stay identical throughout the fixed term
• Protection against interest rate rises
• Early repayment charges usually apply

Best for: Budget - conscious borrowers who value payment certainty

What is a Tracker Mortgage?

Tracker mortgages follow an external rate (usually the Bank of England base rate):

• Rate = Base Rate + fixed margin (e.g., 1.5%)
• Payments fluctuate with base rate changes
• Often no early repayment charges
• Some have a collar (minimum rate) and cap (maximum rate)

Best for: Those comfortable with payment variability who believe rates may fall

What is a Variable Rate Mortgage?

Standard variable rate (SVR) mortgages:

• Lender sets rate at their discretion
• Typically the highest ongoing rate
• No early repayment charges
• Payments can change at any time

Best for: Short-term borrowing or those planning to remortgage soon

What is an Offset Mortgage?

Offset mortgages link your savings to your mortgage:

• Savings balance "offsets" mortgage debt for interest calculations
• Pay interest only on the net difference
• Maintain access to your savings
• Potentially significant interest savings

Best for: Higher-rate taxpayers or individuals with substantial savings

What is a Discount Mortgage?

Discount rate mortgages offer:

• Reduction from the lender's SVR (e.g., 2% below SVR)
• Discount period typically lasts 2-3 years
• Payments vary if SVR changes
• Early repayment charges usually apply

Best for: Those expecting to remortgage before the discount ends

Common Misconceptions

• ✗ "Fixed rates are always safest" - Can be expensive if rates fall
• ✗ "Trackers are too risky" - Capped products limit exposure
• ✗ "Offset only benefits the wealthy" - Useful for anyone with savings
• ✗ "You're stuck with your choice" - Most can remortgage later

Current Market Trends (2024)

• Fixed rates: Average 2-year fix at 4.5%, 5-year at 4.2%
• Trackers: Typically 0.5% above base rate
• Offset mortgages: Growing popularity as savings rates rise
• Product diversity: More hybrid options emerging

Frequently Asked Questions

Should I fix for 2 or 5 years?

Depends on rate outlook and plans - 5-year gives longer certainty but may have higher early exit fees.

Can I switch mortgage types later?

Yes - most remortgage to different products when their deal ends.

Are tracker mortgages cheaper?

Currently often more expensive than fixes but may be better positioned if rates fall.

How much can offset mortgages save?

A £50,000 savings offset could save £1,500+ annually at 3% interest. Illustrative only. Actual savings will depend on your rate, balance, and lender terms.

What happens when my fixed rate ends?

You'll move to lender's SVR unless you remortgage - usually much higher.

Conclusion

Choosing between fixed-rate, tracker, and offset mortgages depends on your personal circumstances, attitude to risk, and future plans. Fixed rates can offer predictable payments, trackers may suit those expecting rates to fall, and offset mortgages could reduce interest costs for those with savings.
