Has anybody been able to port an existing mortgage to a new house and been allowed to extend the term of it? I have an amazing mortgage deal at my current property but the new house is a lot more expensive than my current house so I will be borrowing extra and resetting the term back to 25 years. I know that they won't let me borrow more at this rate and I'll need to probably have two mortgages running side by side. My mortgage does have a port facility but I have no idea if they'll allow me to extend the term. Anybody with some positive examples?
