Many mortgage customers often seem to think that they need to take out a mortgage over 25 years initially. In fact you can choose any term between 5 and 40, depending on your monthly budget and your current age. mortgage2move usually recommend aiming for a target age so, subject to affordability, eg: if you are, say, 26 years old now, you may want to opt for a 24 year term, so it will be paid by age 50!
