Mortgage Brain has added new dedicated buy-to-let lender, Rely, to its Sourcing Brain and Criteria Brain modules.

Rely, which was officially launched by OSB Group last week, aims to provide brokers with an easier and faster way to transact buy-to-let mortgages on behalf of their landlord clients. The new partnership with Mortgage Brain will enable brokers to access Rely’s full range of buy-to-let mortgage products.

Lender product information across both Sourcing Brain and Criteria Brain is updated twice daily, giving intermediaries the most accurate and up-to-date results for their clients.

“Through Sourcing Brain and Criteria Brain, Rely can offer brokers even greater accessibility to our data-driven lending platform, helping them find solutions faster, manage risk more confidently, and deliver exceptional outcomes for their clients.”
