The Chesham Building Society has built up a reputation for security and stability (over 160 years of business should be testament to that!) and offer you flexible tracker and flexible buy to let mortgages.
The Chesham Building Society is a mutual institution which means the Chesham is owned by its members. This means they are fully accountable to them, and don't have shareholders to satisfy and some would argue this gets a much better deal for its members. As an example instead of paying dividends they can return profits to their members in the form of better savings and mortgage rates.
