Property company Hibernia REIT has announced a pre-tax profit of €73.7m for the six months to the end of September.
The figure is more than double the amount recorded in the same period of 2014, and includes gains from the revaluation of some assets as well as disposals.
Hibernia REIT owns 21 investment properties across Dublin, which it values at almost €740m.
The company today declared at interim dividend declared of 0.7 cent per share, up from 0.3 cent per share the same time last year.
Hibernia REIT also announced today the signing of a €400m revolving credit facility.
The deal is four times the size of a previous arrangement it had, which it said will give it flexible funding to move quickly on any opportunities that emerge.
Kevin Nowlan, the company's chief executive, said Hibernia was pleased with the performance for the first half of the year, adding that it had made significant progress on its development portfolio as well as signing two major pre-lets.
"Hibernia’s strategy and skillset - allowing us to access off-market deals, loan portfolio opportunities and to take on major development and refurbishment projects - is clearly delivering," Mr Nowlan added.
"The Dublin property market is well supported by the economic growth Ireland is enjoying and with new, flexible funding in place allowing us to act quickly as opportunities arise we are optimistic for the future," he stated.
The company said it has invested a total of €600m in acquisitions since its IPO in December 2013, including a deal to buy the apartment development Dundrum View in South Dublin for €28m in June and office blocks in Lime Street and Lower Camden Street.
Hibernia said it expects the Irish economic backdrop and dynamics in Dublin occupational markets to remain favourable, and there to be further rental growth, especially in the Dublin city centre..
In the investment market, it said it expects the volume of deals in Dublin to remain at "elevated levels" in the near term. It said it is tracking a number of potential acquisitions, both large and small.
"These facts, together with the exciting opportunities we are exploiting within our existing portfolio, make us optimistic about the future," the company added.
