Mortgages for Business and Aldermore Commercial Mortgages have launched Keystone Buy to Let Mortgages, a new buy to let mortgage funding line for professional property investors.

The funding will be provided by Aldermore Commercial Mortgages while the whole application process will be carried out exclusively by Mortgages for Business.

The product range is aimed at both individual and limited company investors who already own at least one residential investment property. The range includes a selection of fixed and discounted rate buy to let mortgages for vanilla, HMO and multi-unit property.

David Whittaker, managing director of Mortgages for Business, said: “Over the last few years it’s been increasingly difficult for professional landlords with decent sized portfolios to secure funds for medium-sized loans. This has not only inhibited their ability to purchase ‘vanilla’ buy to let property but also means they struggle to find finance for more complex deals such as HMOs or multi-unit properties and to make acquisitions in limited company vehicles.
