The deals are available through directly authorised brokers and will allow up to 95% of the share to be purchased, with the share being between 25% and 75% of the property value.
Both discounted and fixed-rate products are available with no upfront fees and they apply to houses in England and Wales.
Loughborough BS business development manager Ashley Pearson (pictured), said the lender realised through research and discussions with housing associations and intermediaries that there is an increasing demand for this type of mortgage.
“I purchased my first home in 2003 using the shared ownership scheme through a local housing association.
“It allowed me the chance at a young age to step on to the property ladder. I feel that it is important as a mutual that we offered this type of mortgage to allow more people to become homeowners,” he added.
