Deals and financing in Ireland’s reenergised build-to-rent market have broken through the €1B barrier this summer, with more than €360M in new deals alone since 1 July, as international investors have been drawn back into a previously stagnant market.

Hopes that reforms to rent cap regulations would encourage global players to look at Dublin again appear to have been validated, as capital from Germany, the U.S., the Netherlands and Ireland has circled the residential sector once more.

Now the question is whether deals for existing stock can encourage investors and developers to start the construction of much-needed new homes in the Irish capital and beyond.

“There are reasons for greater confidence. Recent changes to rent regulation, apartment standards and zoning should help improve development viability and investor sentiment,” Savills Investment Director Kevin McMahon told Bisnow.

“Financing costs remain a challenge, but if investors continue to see liquidity and pricing certainty returning to the Dublin market, we expect that to support renewed appetite for development and ultimately help bring more schemes forward.”

That is particularly important in Dublin, where rental supply remains extremely tight and underlying demand continues to grow, he added.

In the most recent deal of the summer splurge, German investment manager Quantum Immobilien completed its acquisition of the 268-unit Quayside Quarter in Dublin’s North Docks from Greystar for about €180M.

Previously, Munich Re asset manager MEAG acquired the 140-unit Seafield Strand scheme in Sutton for around €67M, while Irish Residential Properties REIT is closing in on a €115M-plus purchase of the 282-unit Two Three North development in Clongriffin.

That puts the value of those three residential transactions alone at more than €360M. On top of that, M&G Real Estate and Marlet Property Group secured a €732M financing package in August against a portfolio of six Dublin BTR communities containing 1,812 apartments. The package comprises a €550M senior mortgage from Standard Chartered and €182M of preferred equity from Affinius Capital and Macquarie Capital Principal Finance.

Amsterdam-based Redevco also provided a €57.3M green loan to finance a Bain Capital-sponsored 156-unit residential scheme in Dublin 14. Taken together, since 1 July, that amounts to more than €1.1B of BTR-related capital activity.

Knight Frank estimates Ireland's living sector could attract €800M to €1B of investment during 2026, driven largely by international capital. Multifamily dominated activity in the first half and is expected to remain the leading living sector investment category.

CBRE has also identified residential as one of the key sectors in a new investment cycle. Residential accounted for 31% of Irish investment volumes in the first half, while a broader group of international buyers has begun entering the market.

Ireland's regulatory changes have clearly helped. The March rental reforms have provided investors with greater clarity around rent-setting and the ability to reset rents to market levels once units are vacated.

Savills' McMahon said the return of international capital and greater evidence of liquidity are important for the wider market, particularly given how constrained new housing delivery remains.

Quantum’s Quayside Quarter acquisition marked the German manager’s market entry into Ireland. The property comprises 268 privately financed apartments across eight buildings.

Completed in 2021, it is in Dublin Landings on the north bank of the Liffey. Greystar, which acquired the property in 2019, will remain in place as manager.

And Quantum may not be finished yet, establishing a local presence in Dublin and signalling that it is looking at other opportunities.

Likewise, MEAG's €67M acquisition of Seafield Strand in Sutton was its fourth Dublin investment in little more than six months, with the 140-apartment scheme completed in 2023 and previously owned by Union Investment. MEAG had already bought the 162-unit 18 Newmarket Square residential scheme for €75M and One Molesworth Street for €110M and acquired the two Dublin Landings offices late last year.

The potential Two Three North acquisition by IRES REIT is another indication that the revival is reaching Ireland's listed residential sector. IRES has been selected as preferred bidder for the 282-unit Clongriffin development. That transaction is expected to exceed €115M.

The scheme contains 236 private rented apartments and 46 homes leased to Dublin City Council under a 25-year agreement. If completed, the purchase would add roughly 8% to the IRES portfolio, which stood at 3,611 homes at the end of June with a value of about €1.3B.

It also represents a significant change of pace for a company that has spent several years concentrating on its existing portfolio, selling assets, strengthening its balance sheet and dealing with Ireland's regulatory environment.

“One of the things we wanted to see is more international money attracted to Ireland, and there is early evidence that that’s the case,” IRES CEO Eddie Byrne told Bisnow in an interview earlier this year, adding that the company was also looking at potential joint ventures with international partners.

And transactions could have been even higher had DWS Group not shelved plans to sell a €200M-plus BTR scheme in Dublin, which had attracted interest from Norges and GIC.

Perhaps the biggest indication of where the market could go is Kennedy Wilson's partnership with Dutch giant APG. The two launched a €2B residential development and asset management platform covering more than 3,400 private rented homes.

It includes APG's existing 1,100-plus-unit Cherrywood portfolio and around 2,300 homes planned across Player Wills, Bailey Gibson and Clonliffe in Dublin. More than 700 homes at Player Wills are already moving into construction, with work on the remaining 1,500-plus units expected to begin in 2027.

The next test will be whether investment capital can translate into significant new supply. If it can, Ireland's BTR market may be entering not just a recovery and reset phase but also a second institutional cycle involving larger platforms, deeper pools of international capital, and investors increasingly willing to treat rental housing as a core European real estate sector rather than an opportunistic bet.
