The deals included in the LTV increase include a 3-year discounted variable rate at 2.44% (home purchase) and a 3-year discounted variable rate (remortgage) at 2.66%.
James Bawa, chief executive of Teachers Building Society, said: “Teachers Building Society is committed to helping as many people as possible to move onto the property ladder.
“We are implementing a range of changes to our products, increasing the LTV from 75% to 80% which will make the products available to a wider audience.
“We are committed to offering a range of good value products to teachers across the UK and local residents, and these changes are all part of that process.”
Colin Dorman, national account manager, added: “These mortgages, available through the intermediary channel are now available to buyers at an increased LTV of 80%.
“This along with our new specialist products and our approach to manual underwriting without credit scoring make our proposition stand out to intermediaries.”
