A modern approach to age old problems

Today, there are literally thousands of mortgage products available from a host of lenders. Despite this, there are very few real differences between the vast majority of them - there has been little or no innovation in the mortgage market during the last decade.

For many of our mortgage customers, the more traditional options available in the marketplace fail to address a fundamental mismatch: customers with high quality assets but with relatively low incomes find it difficult to borrow at reasonable rates and on sensible terms. Until now.

We recognise that there is a large and under-served audience in the experienced buy to let, self employed and high net worth mortgage markets. These customers need tailored solutions that take account of their broader financial position. They need a lender who recognises that cashflow and net worth are not the same thing.

Our customers also want to choose when and how they service their interest. Some prefer to pay their interest each month in full whilst others want more flexibility in managing their cashflow. Our products offer real choice.
