Once you have your AIP you can pick your rate and apply for your remortgage.

Great, now tell us a bit about you

You’ll need to tell us who’s applying, your pre-tax annual income, and if you have any dependants.

Next, tell us about your expenses?

We’ll need this information to understand how much you could afford for a mortgage.

Finally, we just need these last few details

Let us know how much deposit you have and how long you'd like to pay the mortgage over.
