What actually goes wrong for Irish landlords in 2026

7,062. That is how many Notices of Termination Irish landlords sent the Residential Tenancies Board in the first three months of 2026, up 50.5% on the same quarter a year earlier and the highest quarterly figure the RTB has published since the series began. The previous peak was 5,735.

The interesting part is the reason column. Only 764 of those notices, 10.82%, were served because a tenant breached their obligations. 4,259, just over 60%, were served because the landlord intended to sell. Whatever is pushing landlords out of the Irish rental market, it is overwhelmingly not the tenants.

This is not another piece about landlords leaving, which is covered in why small landlords are leaving the Irish market, nor about spreadsheets, covered in spreadsheets versus property software. This is about what actually breaks week to week: the notice served a day late, the arrears nobody flagged in week 3, the repair with no timestamp, and the tax return rebuilt from a shoebox every October.

The exit is not about bad tenants

Set the Q1 2026 reasons side by side and the picture is hard to misread. Intention to sell, 4,259 notices. Landlord or a family member moving in, 1,338. Tenant breach, 764. Property no longer suitable for the tenant, 75.

A year earlier, in Q1 2025, the RTB received 4,693 notices in total and 2,518 of them cited sale. So the total rose 50.5% while sale notices rose by roughly 69%. The share citing sale went from 53.65% to 60.31%.

The monthly split is the part worth pausing on. January produced 1,998 notices, March 1,926, and February 3,138, which was 97.4% up on February 2025. The new regime commenced on 1 March 2026. A large number of landlords moved before the rules changed, which tells you the change itself was read as a reason to get out.

This is happening while the register grows, not shrinks. There were 246,477 registered private and cost rental tenancies at the end of Q1 2026, up 2.4% on the year, and 105,847 private landlords, up 1.3%. Approved Housing Body tenancies rose 11.9% to 57,330 and cost rental rose 87.4% to 5,226. Demand is absorbing everything that comes free, which is why a record quarter of exits and a growing register are not a contradiction.

Disputes are climbing with it. The RTB took 2,807 applications for dispute resolution in Q1 2026, up 17.6% year on year, and the top three reasons were rent arrears, overholding, and breach of landlord obligations.

Geographically it concentrates where the stock is. Dublin accounted for 2,518 notices, 35.7% of the national total, followed by Cork on 739, Galway on 446 and Limerick on 354.

None of that is a tenant problem. It is a margin and workload problem, and workload is the half a landlord can control. All of the figures above come from the RTB Director’s Quarterly Update, May 2026 and its Q1 2026 Notices of Termination release.

The compliance calendar that never stops

A small landlord is running several statutory clocks at once, and none of them pause for a day job. Registration is due within 30 days of the tenancy starting. A Notice of Rent Setting is compulsory at the start of every new tenancy and has to reach the tenant and the RTB, not just one of them. Notice periods scale with tenancy length, from 90 days under 6 months up to 224 days past 8 years.

Individually none of these are difficult. The difficulty is volume and memory. Three properties means 3 registration cycles, 3 rent review dates and however many arrears and repair threads are open, tracked across email, a diary and a phone reminder. Miss one and the consequence is not a warning: an unregistered landlord cannot serve a valid notice of termination for rent arrears. The RTB issued 151 compliance notices for failure to register in Q1 2026, along with 21 court summonses, and completed court enforcement in 6 cases. It has published 19 sanctions in 2026 with a combined value of EUR 78,849. See RTB registration and the 2026 rental rules.

Rent setting under the 2026 rules

Since 1 March 2026 rent can go up once every 12 months by 2% or inflation measured on the Consumer Price Index, whichever is lower. Apartments where construction commenced after 10 June 2025 follow inflation with no 2% ceiling. Rent Pressure Zones are gone, because the whole country is now covered.

The RTB and ESRI Rent Index put the standardised average rent for a new tenancy at EUR 1,755 in Q4 2025, against EUR 1,503 for an existing tenancy. New tenancy rents rose 5% over the year and existing tenancy rents 4.4%. In Dublin the same comparison is EUR 2,232 against EUR 1,939. That national gap of EUR 252 a month is the number quietly sitting behind a lot of decisions about whether to re-let or hold, and it is also why the rules on when you may reset to market rent matter so much.

You may only set market rent if the previous tenancy ended because the tenant left by choice, breached their obligations, or the property no longer suited them, and you must evidence it with 3 comparable dwellings from the RTB Rent Register. After a no-fault ending such as a sale that falls through, you are on the capped route. Work the figure out with the rent increase calculator and check the paperwork with the RTB rent review notice checker before anything goes out.

Ending a tenancy without invalidating the notice

Since 1 March 2026 your own size decides which grounds you have. A small landlord is not a company and holds 3 or fewer tenancies, and keeps sale, family occupation, refurbishment and change of use, at defined points in a rolling 6 year Tenancy of Minimum Duration. A large landlord is a company or holds 4 or more, gives an unlimited duration tenancy after 6 months, and may only end it for tenant breach or unsuitability.

Then the notice itself has to be right. Periods run 90 days under 6 months, 152 days from 6 months to a year, 180 days from 1 to 7 years, 196 days from 7 to 8, and 224 days beyond. Breach is 28 days after a warning notice, and serious anti-social behaviour is 7 days. A copy must reach the RTB the same day it is served on the tenant, or the notice is invalid. Given that 4,259 landlords served a sale notice in one quarter, the cost of getting this wrong is not theoretical. See notice of termination periods and Part 4 tenancy rights.

Arrears, and whoever has the clearer record

Arrears rarely arrive as a crisis. They arrive as a payment that is 6 days late, then 3 weeks, then a quarter. The landlord who notices in week 1 is having a conversation. The landlord who notices in week 10 is opening a dispute file.

An RTB adjudicator works from evidence: payment dates, what was sent, when a warning issued, whether the rent was lawfully set in the first place. A landlord working from bank statements and memory is at a structural disadvantage against a tenant with a rent book, even when the landlord is factually right. The full process is in chasing rent arrears in Ireland.

Maintenance, and the timestamps that protect you

A boiler failure is not a compliance event. It becomes one the moment a tenant says the property fell below the standards in the Housing (Standards for Rented Houses) Regulations 2019, which cover heating, sanitary facilities, structural repair, ventilation and fire safety.

What protects a landlord then is timing: when the request came in, when it was acknowledged, when a contractor was booked, when the work finished. A text thread on a personal phone is weak evidence next to a logged record tied to the property and the tenancy. This is a quiet reason landlords lose disputes they should win.

The October reconstruction project

Irish rental income is taxed under Case V, and every deduction has to be tied to a specific property and date. For 1 property a folder is fine. For 3, across tenancies with different review dates, rebuilding a full year from bank statements and paper receipts each October is the most dreaded job in the calendar.

It also costs money, because the expenses that go missing are the small ones, and they are the ones that reduce the bill. Estimate the liability before the return is due with the Irish rental income tax calculator.

How Rentalize helps

Rentalize is built around that list rather than a generic property database. Registration dates, rent setting deadlines and the first lawful review date are held per tenancy and raised before they fall due. A rent increase is calculated against the correct ceiling from the live CPI figure instead of by hand, and notice periods are matched to how long the tenant has been there, so the right notice goes out rather than a guess.

Arrears surface in the week they start, with a dated record you can hand an adjudicator. Repairs are timestamped from the moment a tenant raises them. Rent and expenses are tied to the property they belong to, so October is a report rather than a reconstruction. Rentalize for landlords covers the single owner case and letting agent software the managed portfolio, with plan detail on Rentalize Core and collection on Rentalize Pay.

If you only ever use one thing, make it the free tenancy agreement generator. It produces the agreement, the Notice of Rent Setting, an inventory and a dated compliance checklist, and it blocks a rent or deposit above the lawful maximum before you sign anything.

If the list above reads like an ordinary Tuesday, the pricing page shows what each plan covers, whether that is 1 property or 30.

Frequently asked questions

Why are so many Irish landlords issuing Notices of Termination?

The RTB received 7,062 Notices of Termination in Q1 2026, the highest quarterly total in its published series and 50.5% above Q1 2025. 4,259 of them, 60.31%, were served because the landlord intended to sell the property. Only 764, 10.82%, cited a tenant breach, so the exit is being driven by owner economics rather than tenant behaviour.

How much can a landlord raise rent in Ireland in 2026?

Since 1 March 2026 rent can be increased once every 12 months by 2% or the rate of inflation measured on the Consumer Price Index, whichever is lower. Apartments in developments where construction commenced after 10 June 2025 follow inflation with no 2% cap. A Notice of Rent Setting must also go to the tenant and the RTB at the start of every new tenancy.

What is the difference between a small and a large landlord?

A small landlord is not a company and holds 1 to 3 tenancies. A large landlord is a company, or holds 4 or more. Small landlord tenancies run in rolling 6 year Tenancies of Minimum Duration and keep grounds such as sale and family occupation at defined points. Large landlord tenancies become unlimited duration after 6 months and can only be ended for tenant breach or property unsuitability.

What is the gap between new and existing tenancy rents in Ireland?

The RTB and ESRI Rent Index recorded a standardised average rent of EUR 1,755 for new tenancies in Q4 2025 against EUR 1,503 for existing tenancies, a national gap of EUR 252 per month. In Dublin the figures were EUR 2,232 and EUR 1,939. Resetting to market rent is only permitted in specific circumstances, so the gap cannot simply be claimed at will.

How long is the notice period to end a tenancy in Ireland?

It depends on how long the tenancy has run on the day the notice is served: 90 days for under 6 months, 152 days from 6 months to 1 year, 180 days from 1 to 7 years, 196 days from 7 to 8 years, and 224 days beyond that. Tenant breach is 28 days after a warning notice and serious anti-social behaviour is 7 days. A copy must reach the RTB the same day, or the notice is invalid.

What happens if a landlord does not register a tenancy with the RTB?

Registration is due within 30 days of the tenancy start date. An unregistered landlord cannot serve a valid notice of termination for rent arrears, and the RTB can impose sanctions of up to EUR 15,000 for improper conduct plus up to EUR 15,000 in investigation costs. In Q1 2026 the RTB issued 151 compliance notices for failure to register and 21 court summonses, and it has published 19 sanctions in 2026 worth EUR 78,849.
