What is the shortest mortgage term?

Typically the shortest mortgage available is ten years

The shortest mortgage term is usually ten years from the date it is granted. If the term you require is shorter than that, say five years, then a bank will tend to suggest you consider a personal loan.

You can, of course, reduce the term of a mortgage by overpaying on it during its term. You will always need to be aware of any redemption penalties and factor them into your decision-making on whether to make additional payments.
