Does anyone know of any really good repayment mortgages out there at the moment

They are all the same.

You pay more principle, you lower your balance. The bi-weekly one works well, UNLESS you are paid monthly.

Just pay an extra 100 every month works well too.

All depends what mortgage you've got know, whether it is fixed or not and how long you got a decent rate for. Interest rates are as high as they've been for a while and another rate rise of .25% is expected this month. You could try moneysupermarket.com, that site looks at lots of mortgages for you

In which state are u located? contact parsecloans.com for total consulting

the last one tells you an approximate figure of how much you will paying off of your balance per month - I find it quite useful.
