Irish Rental Property in 2026: What the Numbers Actually Show

The income case for a leveraged Irish rental has largely gone. What remains is a leveraged bet on house prices — which is a legitimate position, but a different one from the passive income most landlords think they are buying.

Irish property prices are now well past their Celtic Tiger peak. The CSO index stands roughly 26% above its April 2007 high, with a median price of €395,000 in the twelve months to May 2026 and annual growth of 6.2% — the slowest rate since early 2024, but still growth.

The fundamentals behind that are unlikely to reverse quickly. Ireland needs somewhere in the region of 50,000 homes a year and has been delivering closer to 30,000. Population is rising, migration is substantial, and most new arrivals rent before they buy. Rental listings nationwide sit in the low thousands at any moment.

None of which answers the question a prospective landlord should be asking, which is not whether prices will rise but whether the return on their own capital justifies the risk, the tax and the work.

What changed in March 2026

The rental reforms are usually reported as uniformly bad for landlords. They are not, and getting this right matters because the negative half is widely repeated while the compensating half is not.

On the restrictive side: rent increases are capped nationally at the lower of CPI or 2% a year. New tenancies from 1 March 2026 run as six-year Tenancies of Minimum Duration. Landlords with four or more tenancies can no longer terminate for sale, renovation or change of use — only for tenant breach or where the property genuinely no longer suits the household. Smaller landlords retain limited additional grounds, including family occupation and financial hardship.

On the other side, and less often mentioned: at the end of each six-year tenancy, landlords may reset the rent to market — so the 2% cap compresses income within a tenancy rather than permanently. That reset is forfeited where a no-fault eviction has occurred in the preceding period. Newly built apartments with a commencement notice on or after 10 June 2025 sit outside the 2% cap entirely and are limited only by CPI. And all landlords can sell with a tenant in situ at any time.

Two further points. The inflation measure switches from the eurozone HICP to Irish CPI, which will sometimes allow slightly more. And the new regime applies only to tenancies created from 1 March 2026 — existing tenancies continue under the previous rules, so many portfolios now run two parallel regimes at once.

A worked example

Take a one-bedroom apartment in Dublin 4 at €275,000, achieving €1,900 a month. Assume a 30% deposit, €6,000 in stamp duty and legal fees, and €8,000 of refurbishment. Total cash in: €96,500. The mortgage of €192,500 at 5.5% over 25 years costs €14,186 a year.

Metric Result Interpretation

Gross yield 8.3% Rent ÷ price. Strong on the face of it

Net yield 7.2% After €3,000 running costs

Cash-on-cash, pre-tax 5.8% €5,614 net cash flow ÷ €96,500

On those numbers the deal looks defensible. This is where most analysis stops, and where it goes wrong.

The tax step almost everyone gets wrong

It is tempting to take the €5,614 of net cash flow and apply a marginal rate of up to 52% to it, arriving at something near 2.8%. That is not how Irish rental income is taxed, and the real answer is considerably worse.

Tax is charged on rental profit, not on cash flow. Mortgage interest is deductible. Mortgage capital repayment is not. In year one, roughly €10,500 of that €14,186 is interest and €3,686 is capital.

So taxable profit is €22,800 less €3,000 of allowable costs less €10,500 of interest — around €9,300. At 52% that is a tax bill of about €4,836, set against net cash flow of €5,614.

After-tax cash return: roughly €780 on €96,500 invested. That is 0.8%, not 2.8%.

You are taxed on more than you receive in cash, because the portion of your mortgage payment that repays capital is not an expense in Revenue’s eyes. Any leveraged rental analysis that skips this step overstates the income return substantially.

What is actually holding the return up

That 0.8% is not the whole picture either — and the same analysis that corrects the tax has to be honest about what it leaves out.

The €3,686 of capital repaid is not lost. It is equity, and on €96,500 of invested cash it is worth 3.8% a year. Add it to the after-tax cash and you have roughly 4.6% before any movement in the property’s value.

Then there is capital growth, and this is where leverage does its work. A 3% rise on a €275,000 asset is €8,250, which on €96,500 of equity is 8.5%. Put the three together and the total return approaches 13%.

This is the step routinely missed in comparisons between property and funds. Setting a property’s rental yield against a diversified portfolio’s total return is not a like-for-like comparison, because one figure includes capital appreciation and the other does not.

But run it the other way and the same leverage is unforgiving. At zero capital growth the return is that 4.6%. At minus 3% it is roughly negative 4%. A 10% fall in the property’s value wipes out more than a quarter of the equity. Leverage does not create return; it magnifies whatever the asset does.

Which reframes the decision honestly. On these numbers the income return is close to nothing after tax. Almost the entire case rests on capital appreciation, amplified three-to-one by borrowing. That is a coherent investment thesis. It is simply not the passive income proposition most people believe they are buying.

One further point that cuts against the property side and is rarely modelled. The 2% cap applies within a tenancy, and the reset to market comes only at the end of a six-year term. If your costs rise faster than 2% — and insurance, management fees, maintenance and waste charges have all been doing so — real income compresses for up to six years at a stretch before it can be corrected. The reset repairs the position; it does not compensate for the intervening years.

The comparison worth making

Against a pension, the contrast is stark and largely about the wrapper. Contributions attract relief at your marginal rate, growth is untaxed, and there is no exit tax or deemed disposal. Rental profit is taxed annually at up to 52% with no shelter at all.

Against a personally held fund portfolio the gap narrows considerably. Irish and EU-domiciled funds attract exit tax at 38% following Budget 2026, with a deemed disposal every eight years, so quoting a confident after-tax figure for an ETF is doing exactly what the property analysis above was criticised for. Whatever return assumption you use, apply it consistently to both sides.

The defensible statement is narrower: property is the only one of the three that lets an ordinary investor use significant leverage, and the only one that requires ongoing work and carries regulatory risk. Whether that trade is worth making depends entirely on your view of Irish house prices over your holding period, and on whether you want the job.

Two costs are also missing from every yield calculation above. Vacancy — even a month between tenancies removes roughly €1,900, which is more than twice the entire after-tax cash return in this example. And your own time, which for a self-managing landlord is real and unpaid. Neither appears in a gross yield, and both fall directly on the thinnest part of the return.

Who it still suits

• The low-leverage holder. Cash buyers or those with small mortgages, seeking a modest inflation-linked yield and a long-term store of value rather than a high return, and willing to pay for management so the holding is genuinely passive.

• The operator. Someone running a property business rather than owning a rental — systems, likely a corporate structure, and an edge that comes from refurbishment, scale, or finding mispriced stock. The return comes from the work, not the asset.

Between those two positions sits the accidental landlord with one leveraged apartment, no particular edge, and a full-time job elsewhere. That is the position the last few years have been hardest on, and it is worth reviewing rather than continuing by default.

The question is not whether the property is cash-flow positive. It is what your capital is earning after tax, after the work, and after honest assumptions about growth — and whether you would buy it again today at its current value.

Frequently asked questions

Is buy-to-let still worth it in Ireland in 2026?

On a leveraged purchase at current prices and rates, the after-tax income return is close to zero. The case rests on capital appreciation magnified by borrowing, and on the value of the equity built through capital repayment. Whether that is worth it depends on your view of house prices and your willingness to take on the regulatory and management burden.

How is rental income taxed in Ireland?

Rental profit is taxed at your marginal rate, potentially up to 52% including USC and PRSI. Mortgage interest is deductible against rental income; mortgage capital repayments are not. This means you are frequently taxed on more than you receive in cash.

What are the rent rules from March 2026?

Rent increases are capped nationally at the lower of Irish CPI or 2% a year. New tenancies from 1 March 2026 run as six-year Tenancies of Minimum Duration, with rent reset to market permitted at the end of each six-year period unless a no-fault eviction occurred. Newly built apartments commenced on or after 10 June 2025 are outside the 2% cap.

Can landlords still evict tenants in Ireland?

Landlords with four or more tenancies cannot terminate a post-March 2026 tenancy for sale, renovation or change of use — only for tenant breach or where the property no longer suits the household. Smaller landlords retain limited additional grounds. All landlords can sell with a tenant in situ at any time.
