How Each Mortgage Works

Feature	Details
Interest rate	Locked at agreed rate
Term	Usually 2, 5, or 10 years

Tracker Mortgage

Interest rate	Base rate + margin
Typical margin	+0.5% to +2% above base rate
When base rate changes	Your rate changes automatically

Current Market Considerations

Rate Environment Analysis

Market Condition	Favours
Rates at historic lows	Fix (lock in low rates)
Rates expected to fall	Track (benefit from cuts)
Rates expected to rise	Fix (protect from rises)
Rates at peak, falling expected	Track (ride them down)
Uncertain outlook	Fix (for certainty)

Decision Framework

Question	If Yes	If No
Can you afford 2% rate rise?	Tracker possible	Fix
Do you value certainty?	Fix	Tracker possible
Planning to relocate <5 years?	Check ERCs	Either
Expect rates to fall soon?	Tracker	Fix

Early Repayment Charges

Typical ERCs

Mortgage Type	Typical ERC
2-year fixed	2-3% of loan
5-year fixed	3-5% in year 1, reducing
10-year fixed	5-7% in year 1, reducing
Tracker (term)	Often 1-2% or none
Lifetime tracker	Usually none

ERC Example: £200,000 Mortgage

Scenario	ERC Cost
2-year fix (2% ERC)	£4,000
5-year fix (3% ERC)	£6,000
Tracker (1% ERC)	£2,000
