The products will be available on the online and desktop sourcing systems – MortgageBrain Anywhere and MortgageBrain Classic.
The move will extend the lender’s reach to 22,000 intermediaries.
LendInvest sales director Ian Boden (pictured) said: “Partnering with a market leader in optimising the loan sourcing process like Mortgage Brain, marries directly with our goals as a lender.
“Internally, our team work continuously to alleviate pain-points in the application process, and we strongly believe this should start at the point of search.
“As we ramp up the distribution of our buy-to-let product one year on, Mortgage Brain’s extensive and diverse member-base will be a true asset.”
