The relaunch offers 90% LTV products for first-time buyers, remortgagers and homeowners with smaller deposits.
Notable products include a 2-year fix at 3.29%, and a 5-year fix at 3.69%.
The former deal includes ERCs and a £999 fee, while the latter offers no ERCs, a £499 fee, and is within the lender’s Flexx range.
Both products are available for purchase, remortgage, product transfer and further advances.
Jonathan Stinton, head of intermediary relationships at Coventry Building Society, said: “There’s plenty of demand for 90% LTV products and we’re in a position to support the market by bolstering the supply of these higher LTV deals.
“This provides more choice and certainty for brokers and their clients – particularly first time buyers but also movers and remortgagers.
“By offering a number of 90% deals over controlled periods in 2020, we managed to maintain excellent service levels while offering some respite to those looking for high LTV products.
“Our short-term launches were both popular and effective in the circumstances, but the market for 90% LTVs is now beginning to strengthen.
“We can now continue to support the market this year by offering competitive, high LTV products along with some certainty for brokers that those types of products will be available for some time.”
