LendInvest

LendInvest is a London-based fintech property finance platform and mortgage lender, founded in 2013 after spinning out of Montello Bridging Finance, and listed on the London Stock Exchange AIM market under the ticker LINV since July 2021. It originates and services short-term bridging finance, property development finance, buy-to-let and residential mortgages for UK intermediaries, brokers, property developers, landlords and investors, and runs a parallel capital business that lets individual, corporate and institutional investors put money into secured UK property loans. The company distributes almost entirely through mortgage intermediaries via its Mortgages Portal, and was the first UK fintech to securitise its own buy-to-let loan book. LendInvest publishes no public developer API, developer portal or SDKs; its broker and borrower integrations run through hosted portals rather than a documented public API surface.

LendInvest is profiled on the APIs.io network. Tagged areas include Company, Fintech, Lending, Mortgages, and Property Finance.

LendInvest’s developer surface includes engineering blog, support, signup flow, authentication, and 12 more developer resources.
