The lender announced 2017 had been its busiest year so far and holds a current loan book worth more than £800m, with £7bn in assets under management.
Octopus said the past 18 months had seen it transacting record volumes on a monthly basis.
Deals included its largest ever investment facility, £31.3m for a West London Permitted Development scheme, and its largest development loan, of more than £20m for a Brighton residential scheme.
It was originally focused on residential bridging but branched into residential development in 2011 and commercial lending in 2013.
Last year it added a mainstream commercial term product, as well as seven additional products, including buy-to-let and development exit.
Market evolved beyond recognition
Octopus Property CEO Mario Berti (pictured) noted that £3bn of lending was a fantastic achievement by the business.
He added that the real estate debt market “has evolved almost beyond recognition since 2009, with the sector seeing many new entrants and departures”.
CEO and co-founder Octopus Group, Simon Rogerson added: “Over the last year or so the business has grown rapidly by creating new products to meet an increasingly diverse range of borrowing requirements.
“It has also raised more institutional funds to support its lending activity as it looks to deliver compelling returns to investors who want exposure to the UK real estate market.”
