Investors put off Ireland by tax rates and lack of homes
Housing shortages and high personal taxes are among the principal turn-offs for international companies considering investing in the Republic, according to the IDA.
However, Martin Shanahan, chief executive of Ireland's inward investment agency, insisted the multinationals are "overwhelmingly positive" about Ireland and insisted it was "well-placed" to win more financial services jobs in the wake of Brexit.
Mr Shanahan's comments came as the IDA said that new investments attracted in the first six months of 2017 will lead to the creation of 11,000 jobs despite persistent uncertainty about the structure of the UK's divorce from the EU and potential tax changes in the US.
Just under 2,200 direct new jobs in IDA-supported firms were announced in the period, split roughly evenly between Dublin and the rest of Ireland.
Mr Shanahan said the investment figure is at the same level as the first half of 2016.
