I've been lucky enough to secure a promotion at work and would like to overpay on my mortgage with the additional income.
I've just checked the mortgage calculator on Halifax's website and it says if I pay the amount I want to, it will take 4 years off my mortgage.
Stupid question time - will this be 4 years off my entire remaining term of 20 years if I pay this extra money for that long or will this be 4 years off the remaining 4 years I have with them before my fixed rate expires? So in 4 years I'd have 12 years left instead of 16?
