International millionaires can buy Irish residency for €400,000 under a Department of Justice scheme.
More than 1,400 people have bought residency for themselves and their immediate families since it was set up in 2012.
Amounts ranging from €400,000 to €2 million have to be invested by the applicants, the majority of which are Chinese.
CEO of iCare Housing David Hall says he's used the scheme to raise millions for social housing.
