IRISH HOUSE PRICES ARE ESTIMATED TO BE 17% OVERVALUED IN 2026
Irish residential property prices were approximately 17% above the level suggested by underlying economic fundamentals in the third quarter of 2025, according to new research published by the Economic and Social Research Institute (ESRI) on 4 September 2026.
That is a significant level of overvaluation, but there is an important distinction: the ESRI is not saying Irish house prices are guaranteed to fall by 17%. Nor does its research conclude that Ireland is experiencing a repeat of the credit-fuelled property bubble that preceded the financial crisis. Instead, the researchers argue that the current problem is more closely associated with housing shortages, affordability pressures and house prices rising faster than incomes.
At a Glance
• 17% — ESRI composite estimate of Irish house-price overvaluation in Q3 2025. 🏠
• 10%–24% — Range produced by the different valuation approaches examined. 📊
• Over 40% — Composite overvaluation reached before the financial crisis. 📈
• +5.6% — Annual increase in national residential property prices to June 2026. 💶
• €396,000 — Median dwelling purchase price in the 12 months to June 2026. 🏡
• +26.5% — National property-price index compared with its April 2007 nominal peak. 🔺
• Middle-income households — Identified by the ESRI as facing particularly acute valuation pressures. 👨👩👧👦
The 17% figure relates to Q3 2025 because of the availability of the data required for the ESRI's modelling. More recent CSO price data show that property prices continued rising during 2026.
What does it mean when Irish house prices are 17% overvalued?
"Overvalued" has a more specific meaning here than simply saying houses are expensive.
The ESRI describes overvaluation broadly as a situation where actual house prices exceed the level consistent with economic fundamentals such as household incomes, interest rates, demographics and the supply of housing.
Researchers therefore try to answer a hypothetical question:
Given Irish incomes, mortgage rates, demographics and housing supply, what level of house prices would we normally expect?
They then compare this with actual prices.
The ESRI did not rely on one model. Researchers Paul Egan and Dónal O'Shea combined four different approaches to produce a composite estimate.
Their headline result was approximately 17% overvaluation in Q3 2025. The estimate has also been tested using alternative weightings, which produced composite readings ranging from 15.8% to 18.8%.
That makes the 17% figure more useful as an indicator of the scale of the imbalance than as a precise valuation of every house in Ireland.

How did the ESRI arrive at 17%?
The ESRI used four different approaches to estimate how overvalued Irish residential property was in Q3 2025:
• 24% overvalued — Benchmark economic model. 📊
• 13% overvalued — Vector Error Correction Model (VECM). 📉
• 20% overvalued — Long-term HP trend filter. 📈
• 10% overvalued — Price-to-income measure. 💶
• Around 17% overvalued — Composite measure combining the four approaches. 🏠
The range of results shows why the 17% figure should be viewed as an estimate rather than a precise valuation of every property in Ireland.
This variation is important. There is no single objectively "correct" price for Irish housing that can be calculated with certainty. The ESRI itself stresses that estimating how far property prices deviate from fundamental values is inherently uncertain.
Irish property prices have continued to rise
The ESRI's underlying analysis extends to Q3 2025, but Irish property prices have continued increasing since then.
According to the CSO Residential Property Price Index for June 2026, national residential property prices increased 5.6% in the 12 months to June 2026.
There was a substantial geographical difference:
Ireland overall: +5.6%
Dublin: +4.6%
Outside Dublin: +6.4%
Border region house prices: +10.5%
Midlands house prices: +10.0%
South-West house prices, covering Cork and Kerry: +3.7%
Apartment prices were particularly strong, increasing 8.0% nationally over the same period, including 10.2% outside Dublin.
The median price paid for a residential property in the 12 months to June 2026 was €396,000, according to the CSO. The median ranged from €198,000 in Longford to €682,334 in Dún Laoghaire-Rathdown.
Are Irish houses now more expensive than during the Celtic Tiger?
In nominal euro terms, yes.
The CSO's national Residential Property Price Index stood 26.5% above its April 2007 property-boom peak in June 2026. Dublin prices were 10.9% above their previous peak, while prices across the rest of Ireland were 29.6% higher than their previous peak.
But this comparison needs context.
Nominal prices do not account for inflation. The ESRI calculated that, depending on which inflation measure is used, real house prices remained approximately 3% to 5% below their 2007 peak as of June 2026.
So both of these statements can simultaneously be true:
Irish houses cost considerably more euros than they did at the peak of the Celtic Tiger, but their inflation-adjusted value has not quite returned to the same level.
17% today versus more than 40% before the crash
The ESRI's research shows just how different current levels of overvaluation are from the Celtic Tiger property boom:
• Around 41% overvalued — Q4 2006: The composite measure reached its pre-financial-crisis peak. 🚨
• Around 15%–20% undervalued — 2012: Property prices had fallen substantially following the crash. 📉
• Around 2020: House prices broadly returned to levels supported by economic fundamentals. ⚖️
• Around 17% overvalued — Q3 2025: Overvaluation had increased again, but remained well below the pre-crisis peak. 🏠
• Since 2021: The ESRI found a consistent increase in the level of house-price overvaluation. 📈
The key difference is that today's overvaluation does not appear to be driven by the same excessive lending and household leverage seen before the financial crisis
The direction is nevertheless noteworthy.
The ESRI found that overvaluation has been consistently increasing since 2021.
But the size of the overvaluation is only part of the story. The underlying causes are very different.
Is Ireland experiencing another property bubble?
The ESRI's analysis does not characterise current conditions as another systemic, credit-driven housing bubble.
That distinction matters.
During the Celtic Tiger property boom, soaring house prices were accompanied by rapid credit expansion, loose lending conditions and substantially greater financial vulnerability.
The ESRI's latest analysis finds that household leverage is lower, credit growth is more contained and measures of credit vulnerability remain well below their pre-financial-crisis levels.
The researchers conclude that current conditions are better characterised by structural imbalances in housing supplythan by the emergence of another systemic credit-driven bubble.
In plain English: Irish houses can be overvalued without Ireland necessarily being in a 2007-style property bubble.
What's driving Irish house prices instead?
The ESRI points towards a different combination of pressures.
House prices have been growing faster than incomes, housing supply remains constrained and higher mortgage rates have damaged affordability.
Demographics also matter. Demand for housing is influenced by the size and composition of the population seeking homes, while the supply of properties available to meet that demand affects the equilibrium price.
The ESRI concludes that persistent supply shortages are an important part of the current imbalance.
That makes the current housing problem structurally different from the pre-crash boom.
Middle-income households appear to be getting squeezed hardest
One particularly interesting element of the ESRI research goes beyond national averages.
Researchers examined price-to-income ratios at different points of the income and property-price distribution.
In Q3 2025, overvaluation was positive across the 50th, 75th and 90th percentiles, meaning valuation pressures were not confined to one section of the market.
However, the largest deviation from historical norms occurred around the 50th percentile.
Higher-income households at the 90th percentile experienced materially lower overvaluation relative to their own historical position because their incomes had kept closer pace with house-price appreciation.
This supports an important conclusion: Ireland's housing affordability problem is particularly acute for households around the middle of the distribution.
Why lending rules make 2026 different from 2007
Another major difference is how mortgages are regulated.
Ireland's macroprudential mortgage rules were introduced by the Central Bank in 2015 with the aim of maintaining sustainable lending standards and limiting the relationship between excessive borrowing and house prices.
As of September 2026, the standard loan-to-income limit is four times gross income for first-time buyers and 3.5 times gross income for second and subsequent buyers.
First-time and second/subsequent buyers generally require a minimum 10% deposit.
Lenders have limited allowances to issue mortgages above the standard limits, so the rules are not an absolute ceiling for every individual borrower.
Central Bank of Ireland mortgage measures
The ESRI identifies mortgage rules and stronger banking-sector requirements as factors contributing to the substantially lower level of financial vulnerability compared with 2008.
Worked example: what does 17% overvaluation actually look like?
Suppose we use the CSO's €396,000 national median dwelling price for the 12 months to June 2026 purely as an illustrative example.
If a €396,000 property were exactly 17% above its fundamental value, the calculation would be:
Estimated fundamental value = €396,000 ÷ 1.17
= approximately €338,462
The difference would therefore be:
€396,000 − €338,462 = approximately €57,538
There is an important warning here.
It would be incorrect to conclude from this example that the average €396,000 Irish property "should" cost €338,462 or that its price will fall by €57,538.
The ESRI's 17% is an aggregate economic estimate for the overall residential property market in Q3 2025, not a valuation tool for individual properties.
A house in Cork, an apartment in Dublin and a home in Longford can have completely different local supply, demand and affordability conditions.
Does 17% overvaluation mean house prices will fall 17%?
No.
This is probably the most important misconception to avoid.
Overvaluation is a comparison between observed prices and an estimated level based on economic fundamentals. It is not a house-price forecast.
The gap could theoretically narrow in several ways.
House prices could fall. Prices could remain broadly flat while household incomes increase. Housing supply could improve. Interest rates could change. Or the economic fundamentals supporting prices could strengthen while nominal property prices continue rising.
A market can therefore become less overvalued without experiencing a 17% price crash.
Equally, overvaluation could increase further if property prices continue rising substantially faster than the factors supporting them.
What does this mean for first-time buyers?
For someone trying to buy a first home, the research reinforces the scale of Ireland's affordability challenge rather than providing a signal about the "right" time to buy.
Consider a couple earning a combined €80,000 gross per year.
Under the standard Central Bank first-time-buyer loan-to-income limit, four times income would equal:
€80,000 × 4 = €320,000 maximum mortgage
Assuming a €320,000 mortgage represented 90% of the purchase price, a corresponding property price would be approximately:
€320,000 ÷ 90% = €355,556
The required 10% deposit would be approximately:
€35,556
Yet the national median dwelling purchase price was €396,000 in the 12 months to June 2026.
That creates an illustrative gap of roughly €40,444 between the €355,556 property price supported by the standard mortgage limit in this example and the national median transaction price.
In reality, buyers' circumstances differ considerably. Mortgage approval depends on individual affordability assessments, lenders have limited allowances to exceed standard LTI limits, and eligible purchasers may potentially use housing supports.
But the calculation helps demonstrate why households on otherwise substantial incomes can still struggle to compete in parts of the Irish housing market.
Advantages and limitations of the ESRI analysis
The research provides a much more sophisticated assessment than simply comparing current prices with their 2007 peak.
Its major strength is that it combines several approaches. The benchmark model considers affordability, housing stock and demographics; another model considers variables including output, credit, interest rates and construction costs; while additional measures examine long-term price trends and price-to-income ratios.
The fact that all four approaches indicated some level of overvaluation in Q3 2025 strengthens the overall conclusion.
There are limitations, however.
The different methods produced estimates ranging from approximately 10% to 24%, illustrating the uncertainty involved in estimating a property's theoretical fundamental value. The distributional analysis also requires some historical data to be estimated because complete transaction and income-distribution datasets are not available across the entire period.
The analysis is also national. It should not be interpreted as saying that every county, town, neighbourhood or individual property is exactly 17% overvalued.
Could Irish house prices keep rising despite being overvalued?
Yes.
Overvaluation does not automatically trigger falling prices.
If demand remains stronger than housing supply, purchasers may continue bidding up property prices even when affordability measures indicate that prices are stretched relative to historical fundamentals.
Indeed, the CSO recorded another 5.6% annual increase in national residential property prices in June 2026, after the period covered by the ESRI's Q3 2025 valuation estimate.
That does not tell us what will happen next.
It does demonstrate why "overvalued" and "about to crash" should not be treated as interchangeable terms.
Ireland's Housing Market: 2007 versus Q3 2025
The ESRI finds significant housing-market pressures, but the underlying financial risks look very different from the period before the crash:
• House-price overvaluation: Extremely elevated before the financial crisis, compared with elevated but materially lower levels in Q3 2025. 🏠
• Composite overvaluation: More than 40% at the pre-crisis peak, compared with around 17% in Q3 2025. 📊
• Household leverage: Much higher before the crash; considerably lower by Q3 2025. 💳
• Credit growth: Rapid during the property boom; considerably more contained in the current market. 🏦
• Lending standards: Much looser before the financial crisis; more conservative under today's mortgage lending framework. 📋
• Banking-sector vulnerability: Significantly greater before the crash than in Q3 2025. 🛡️
• Main pre-crisis concern: Rapid house-price growth combined with excessive credit and leverage. 🚨
• Main current concern: High property valuations, affordability pressures and persistent housing-supply constraints. 🏗️
• ESRI conclusion: Current conditions are better characterised by structural housing-supply imbalances rather than another systemic credit-driven housing bubble. 🔍
What should homebuyers take from the research?
The 17% figure should be treated as an economic warning indicator, rather than a prediction of an imminent crash.
For buyers, affordability remains more important than trying to perfectly time the housing market.
Someone considering a purchase should assess what their repayments would look like at their offered mortgage rate, whether they could cope with unexpected expenses or income changes, how long they expect to remain in the property and whether they are stretching their finances simply to compete with other bidders.
The property's own valuation and local market conditions also matter much more to an individual buyer than a national 17% estimate.
For policymakers, the research points towards a different problem: maintaining safeguards around mortgage lending while tackling the shortage of housing that is contributing to affordability pressures.
That is also the direction of the ESRI's conclusion, which argues that policy should remain focused on alleviating supply constraints while maintaining macroprudential safeguards.
Frequently Asked Questions
Are Irish house prices overvalued?
According to ESRI research published on 4 September 2026, its composite measure estimated Irish residential property prices were approximately 17% overvalued in Q3 2025.
Does that mean Irish house prices will fall by 17%?
No. The figure measures the estimated difference between prices and levels supported by economic fundamentals. It is not a forecast of a 17% house-price decline.
How much are Irish houses overvalued compared with 2006?
The ESRI composite measure reached over 40% around the pre-crisis peak, compared with approximately 17% in Q3 2025.
Are Irish property prices higher than in 2007?
In nominal terms, yes. The CSO national property-price index was 26.5% above its April 2007 peak in June 2026. However, ESRI analysis indicates real, inflation-adjusted prices remained around 3%–5% below the 2007 peak, depending on the inflation measure used.
What is the average house price in Ireland?
The more useful CSO measure here is the median transaction price rather than an average. The median price of a dwelling purchased in the 12 months to June 2026 was €396,000.
Is Ireland in another housing bubble?
The ESRI identifies significant valuation pressure but concludes that current conditions are better characterised by structural housing-supply imbalances than a systemic credit-driven housing bubble. Household leverage and credit vulnerabilities are considerably lower than before the financial crisis.
Who is being affected most by high property prices?
The ESRI's distributional price-to-income analysis suggests middle-income households are experiencing particularly acute pressures relative to their historical position.
Will Irish house prices continue to rise?
Nobody can know with certainty. The CSO recorded annual national price growth of 5.6% to June 2026, but historical price movements and valuation estimates cannot reliably predict future property prices.
The Bottom Line
The headline figure is striking: Irish residential property prices were estimated to be approximately 17% overvalued in Q3 2025.
But the context matters just as much.
Ireland's housing market does not currently display the same combination of excessive credit, household leverage and loose lending that characterised the pre-financial-crisis property boom. Instead, the ESRI's analysis points towards a housing market where supply shortages, rising prices, mortgage costs and affordability are creating significant valuation pressure.
For prospective buyers, the research should not be interpreted as evidence that prices are about to fall 17%.
The more practical question remains whether the property you are considering is affordable for you at its current price and mortgage cost, even if market conditions change.
