Non-bank lender, Dilosk DAC, the parent of ICS Mortgages, has raised €500m in new funding.
The money was raised through the securitisation of Irish residential mortgages, made up entirely of Irish owned owner-occupier loans.
It is the company's sixth bond issuance.
All tranches were oversubscribed, the company said, with the seniors and mezzanine tranches going to 21 institutional investors.
"We are delighted to have placed our largest bond issuance since inception at €500 million in size which has been structured to comply with the Simple, Transparent and Standardised (STS) criteria for securitisations enabling us to broaden our investor base," said Fergal McGrath, Dilosk Co-Founder and CEO.
"It represents another positive milestone for Dilosk and our ICS Mortgages brand and will enable our ambitions to increase our share of the Irish mortgage market over time."
Mr McGrath added that while capital markets were volatile last year and in particular over the past few weeks, the successful placement is an indicator of investor confidence in Dilosk's mortgage lending and recognition of the high-quality mortgages that it originates.
"Since 2015, we have now raised c.€1.8 billion through six transactions in the international capital markets," he added.
Non-bank lenders have faced challenging conditions in recent times, as they raise their funding from the wholesale money markets, which have been turbulent and more expensive since interest rates began to rise.
Established in 2013, ICS Mortgages has over €1.4 billion of mortgages under management.
