The building society launched in Hampshire last November and Dorset in 2010 and specialise in mortgages for teachers and education professionals.
Colin Dorman, national account manager at Teachers Building Society, said: “We have seen a dramatic increase in local residents using the society for residential and Buy to Let mortgages in 2013.
“To capitalise on this success, we will now include residents in Wiltshire too. This move takes us closer to our goal of supporting the local Wessex region in attracting non educational business.”
Teachers recently extended availability of its 95% loan to value mortgage product to Newly Qualified Teachers and has lowered the minimum income requirement for residential applicants.
Its mortgages, including Buy to Let, are now available to all teachers, lecturers and teaching assistants in England, Scotland and Wales as well as anyone buying or remortgaging in Dorset, Hampshire and Wiltshire.
