The loan to value (LTV) is essentially the size of mortgage a lender is prepared to offer you in relation to the value of the property you are buying or remortgaging.

It is expressed as a percentage. So, for example, if a lender offers a mortgage deal which has a maximum 80% LTV, that means they will lend you up to 80% of the property value.

Mortgage LTVs typically range from 50% up to 95%
