Previously Accord lent up to a maximum LTV of 85%.
Its new range includes products for house purchase and remortgage, low fee options with fees from £495, and offset deals.
The lender is launching a two-year fix at 4.89% with a £995 fee, a two-year fix at 4.99% with a £995 fee and £600 cashback, as well as a five-year fix at 5.19% with a £995 fee.
Martin McIntosh, mortgage product manager at Accord, says: “Our range of 85% LTV deals has proved to be attractive to first-time buyers and feedback from brokers has shown an appetite for greater competition in the 90% LTV market.
“Our move into this area represents a measured yet positive step, supporting the intermediary market as we embark on a new year of lending.”
Martyn Smith, head of mortgage products at Legal & General Network, says the move marks a very positive start to 2012.
He says: “Accord has been very competitive in the 85% LTV market and the new 90% LTV offering looks just as good with some eye-catching rates and a range of cashback and free valuation solutions. Mortgage intermediaries need more competition from lenders at 90% – and this gives them just that.”
The products have a minimum loan size of £75,000 and a maximum size of £500,000. They are not available for new build properties or flats.
