Buy a property: find your first mortgage, or an additional mortgage for another property.

Remortgage: see if you can get a better rate, or borrow more, on a mortgage you already have.

Residential: this mortgage is for a property you'll be living in.

Buy-to-let: this mortgage is for a property you'll be letting out to someone else (if you'll be a live-in landlord, choose 'Residential').

Capital + interest: you pay off part of your mortgage each month, and interest on top. By the end of your mortgage term, your loan will be paid off in full.

Interest only: you only pay interest on your mortgage each month, but none of the mortgage debt itself. At the end of your term, you'll have to pay it off in full.

The total price of the property, including the deposit amount. If you're not sure, an estimate is fine - you can always check back here again when you've found a place

The total loan amount - this is the money you borrow from lenders and pay back over the term of your mortgage. You'll also pay interest on top of this amount.

Fixed rate: your interest rate (ie what you pay each month) is guaranteed over a fixed period of time, and won't change.

Variable rate: your interest rate could go up or down, so what you pay each month could change. During the initial period, you get a discount on your variable rate.

For the first few years of your mortgage, you'll get a lower than standard interest rate. Think of it like an introductory offer from your lender. You can set how long this lasts here.

The total length of your loan - how many years you'll take to pay back your mortgage.
